ABSTRACT
Spontaneous rupture of brain aneurysmal subarachnoid hemorrhage (aSAH) is a debilitating disease, half of which occurs in individuals under 50 years old. Challenges in its management arise from the decision-making process regarding the preferred method of definitive aneurysm obliteration, whether through surgical intervention or endovascular approach. This study described the role of flow diverter stent as an effective endovascular approach to obliterate aSAH in the acute phase. A 70-yearold female presented with thunderclap headache, slight right hemiparesis, and pupillary-sparing left oculomotor palsy corresponding with ruptured brain aSAH. Endovascular management of flow diverter stent was preferred and inserted within the third day onset. Double antiplatelet was administered prior to and following the procedure. Three-day follow-up showed resolution of brain aSAH with no neurological sequelae. Flow diverter stent offers several advantages over coiling when treating wide-neck, giant, saccular, or fusiform aneurysm. It is also safer for elderly, especially with multiple comorbids, compared with clipping. However, it has risks of either parent/ distal artery occlusion due to its thrombogenic properties or the potential for rebleeding following dual antiplatelet administration. Effective management and thorough evaluation are essential to maximize the likelihood of favorable outcomes when employing this approach. Flow diverter stent is a promising endovascular management for ruptured brain aSAH, particularly in elderly with many comorbids and wide neck/ giant aneurysm at anterior circulation which is not candidate for coiling or clipping. It is also crucial to monitor, evaluate, and manage risk of rebleeding and thrombosis to ensure long-term success of this management approach.

ABSTRACT
Objective To analyze the influence of drainage volume on prognosis of acute hydrocephalus(AHC)after aneurysmal subarachnoid hemorrhage(aSAH)by continuous lumbar drainage.Methods A retrospective trial was conducted on 82 AHC patients after aSAH admitted to the First Affiliated Hospital of Chongqing Medical University between January 2017 and January 2022.In 6 months after discharge,modified Rankin Scale(mRS)score was used to evaluate the prognostic outcomes.Univariate and multivariate logistic regression analyses were performed on demographic factors,severity of subarachnoid hemorrhage(SAH)at admission,medical history,cerebral vasospasm,and lumbar drainage data.Then a nomogram prediction model was constructed.Results Univariate analysis found that World Federation of Neurosurgical Societies(WFNS)score,Hunt-Hess grade,modified Fisher grade,time for continuous lumbar drainage,shunt dependence,cerebral vasospasm,and drainage volume were factors affecting the prognosis of the patients.Then logistic regression analysis revealed that high WFNS score(OR:3.25,95%CI:1.11~9.48),high modified Fisher grade(OR:3.66,95%CI:1.08~12.35),shunt dependence(OR:15.56,95%CI:1.22~198.57),and cerebral vasospasm(OR:22.24,95%CI:3.08~160.68)were independent predictors for mRS score,while volume of continuous lumbar drainage(OR:0.57,95%CI:0.40~0.82)was an independent protective factor.ROC curve analysis indicated a good predictive performance of the model(AUC=0.898,95%CI:0.935~0.861).Internal validation through Bootstrap method demonstrated excellent discriminatory ability of the model(C-index=0.950,95%CI:0.904~0.996;adjusted C-index:0.934).Conclusion Increased volume of lumbar drainage is an independent protective factor for poor prognosis following aSAH and can improve the prognosis of SAH patients.
ABSTRACT
Objective To investigate the relationship between serum mannan binding lectin(MBL),histi-dine rich glycoprotein(HRG),interleukin(IL)-23/IL-17 inflammatory axis and cerebral vasospasm(CVS)and prognosis in patients with aneurysmal subarachnoid hemorrhage(aSAH)after interventional emboliza-tion.Methods A total of 195 patients with aSAH who underwent interventional embolization treatment in the hospital from March 2019 to February 2022 were selected and were divided into no CVS group(126 cases),mild CVS group(18 cases),moderate CVS group(39 cases),and severe CVS group(12 cases)according to the occurrence and severity of CVS detected by digital subtraction angiography at the 4th postoperative day.The levels of serum MBL,HRG,IL-23 and IL-17 among the four groups before and 3 d after surgery were compared.The patients were followed up for 6 months and divided into good prognosis group(137 cases)and poor prognosis group(58 cases)according to their prognosis.Factors influencing poor prognosis in aSAH pa-tients were analyzed by multivariate Logistic regression model.The predictive value of serum MBL,HRG,IL-23,IL-17 levels and their combined application models for poor prognosis in patients with aSAH was analyzed by receiver operating characteristic(ROC)curve.Results The incidence rate of CVS after interventional em-bolization was 35.38%in 195 patients with aSAH.3 d after surgery,the serum levels of MBL,IL-23 and IL-17 in the mild,moderate,and severe CVS groups were higher than those in the no CVS group,those in the severe CVS group were higher than those in the moderate CVS group,those in the moderate CVS group were higher than those in the mild CVS group(P<0.05).The serum HRG levels in the mild,moderate,and severe CVS groups were lower than those in the non CVS group,those in the severe CVS group were lower than those in the moderate CVS group,those in the moderate CVS group were lower than those in the mild CVS group(P<0.05).3 d after surgery,the levels of serum MBL,IL-23 and IL-17 in the four groups were higher than that before surgery,while the levels of serum HRG were lower than that before surgery(P<0.05).The pro-portions of patients with aneurysm diameter≥6 mm,number of aneurysms>1,surgery time>24 h,Hunt-Hess grade Ⅲ/Ⅳ and postoperative CVS,and serum levels of MBL,IL-23,and IL-17 on the 3rd day after sur-gery in the good prognosis group were lower than those in the poor prognosis group,and serum HRG levels at 3 d after surgery in the good prognosis group were higher than that in the poor prognosis group(P<0.05).Multivariate Logistic regression analysis showed that aneurysm diameter≥6 mm,Hunt-Hess grade Ⅲ/Ⅳ and postoperative CVS,elevated serum levels of MBL,IL-23,and IL-17 and decreased HRG level at 3 d after sur-gery were independent risk factors for poor prognosis in aSAH patients(P<0.05).ROC results showed that serum levels of MBL,HRG,IL-23,and IL-17 at 3 d after surgery had certain predictive power for poor progno-sis in patients with aSAH.The predictive model with the combined application of four indicators had relatively high efficiency(the area under the curve was 0.853).Conclusion Elevated levels of MBL,IL-23,IL-17,and decreased HRG levels in aSAH patients after interventional embolization could increase the risk of CVS and are associated with poor prognosis in aSAH patients after interventional embolization.The above indicators have a certain predictive power for poor prognosis in aSAH patients.
ABSTRACT
Objective To investigate the efficacy and safety of Tubridge flow diverter(TFD)in the treatment of ruptured intracranial aneurysms.Methods The clinical data of 13 patients with aneurysmal subarachnoid hemorrhage,who received TFD treatment at the First Affiliated Hospital of Zhengzhou University between March 2019 and Jul 2022,were retrospectively collected.The perioperative materials and follow-up results were summarized and analyzed.Results Successful operation was accomplished in all the 13 patients(13 aneurysms in total).TFD and coil embolization were simultaneously performed in 10 patients(simultaneous treatment),spring coil filling followed by selective staged TFD placement was adopted in 2 patients(staged treatment),and pure TFD placement was employed in one patient.The incidence of perioperative complications was 15.4%(2/13),including asymptomatic ischemic event in one patient and extra-ventricular drainage-related postoperative bleeding in another patient,which caused death of the patient.The median follow-up time was 6.5 months,and 83.3%of patients(10/12)completed cerebral angiography reexamination with DSA.OKM grade D(complete occlusion of the aneurysm)was obtained in 8 patients(80%),and OKM grade C(residual aneurysm neck)in 2 patients.Conclusion For ruptured intracranial aneurysms,TFD implantation is a clinically feasible treatment with favorable safety and efficacy.
ABSTRACT
Objective To investigate the relationship between factors related to the transforming growth factor β(TGF-β)/Aerine-threonine kinase receptors(Smads)signaling pathway and cognitive dysfunction in peripheral blood of patients with aneurysmal subarachnoid hemorrhage(aSAH).Methods The clinical data of 100 patients with aSAH admitted to Chongzuo City People's Hospital from October 2018 to March 2022 were retrospectively selected and grouped according to the patients'Montreal Cognitive Assessment Scale(MoCA)scores,including 54 cases with cognitive dysfunction and 46 cases without cognitive dysfunction.The clinical data,peripheral blood TGF-β,Smad1,Smad3,and Smad7 mRNA expression levels of the two groups were compared.The relationship between pathway-related factors and cognitive dysfunction in patients with aSAH was analyzed in a multifactorial manner.The predictive value of pathway-related factors for cognitive dysfunction in aSAH patients was assessed using the receiver operating characteristic(ROC)curve.Results Peripheral blood TGF-β,Smad1,Smad3,and Smad7 mRNA expression levels were higher in the cognitively impaired group than in the group without cognitive impairment(P<0.05).Multifactorial showed that pathway-related factors were significantly associated with cognitive impairment in patients with aSAH(P<0.05).The ROC showed that the area under the curve(AUC)of pathway-related factors jointly predicted cognitive dysfunction in patients with aSAH was superior to that predicted alone(P<0.05).Conclusion The high expression of factors related to the TGF-β/Smads signaling pathway in the peripheral blood of aSAH patients suggests that this pathway may be associated with cognitive dysfunction in patients.
ABSTRACT
Objective:To study the role of DDX3X/NF-κB pathway in early neuronal apoptosis in subarachnoid hemorrhage(SAH)mice.Methods:The mouse model of SAH was established by internal carotid artery puncture,and the neurological function score of the mice was evaluated.The DDX3X expression was knocked down using recombinant lentivirus expressing DDX3X targeted shRNA(Lv-shDDX3X),or the NF-κB pathway was inhibited by NF-κB-IN-1(IN-1).Western Blot was used to detect the expression of DDX3X and NF-κB(p65)in mouse cortex.TUNEL/NeuN staining was used to detect the apoptosis of cerebral cortex neurons.Results:Twenty-four hours after SAH operation,the neurological function of mice was significantly impaired(P<0.05).While the expression of DDX3X was signifi-cantly increased and the expression of NF-κB(p65)was significantly decreased in the cortex(P<0.05).When the DDX3X expression is knocked down firstly,then SAH surgery is performed.The neurological function of mice was sig-nificantly recovered,and the expression of NF-κB(p65)protein was significantly higher than that in SAH group(P<0.05);If the NF-κB activity was inhibited by IN-1 while DDX3X knockdown,there is no significant recovery of neuro-logical function in SAH mice.TUNEL/NeuN staining showed that the number of TUNEL-positive neurons in the brain tissue after DDX3X knockdown was less than that in the SAH group(P<0.05),while the number of TUNEL-positive neurons was not significantly reduced when IN-1 was used to inhibit NF-κB activity at the same time of DDX3X knock-down.Conclusion:DDX3X/NF-κB mediated cell death in mice with early brain injury after SAH.
ABSTRACT
Objective To explore the neuroprotective effect of asiatic acid(AA)on brain damage after experimental subarachnoid hemorrhage(SAH)in rats.Methods A total of 108 adult SD rats were divided into the sham1 group,the SAH+vehicle group and the SAH+AA group,with 36 rats in each group.The 42 rats were divided into the sham2 group,3,6,12,24,48 and 72 h after SAH groups,with 6 rats in each group.Except the sham group,SAH model was established by unilateral external carotid artery puncture method in other groups.After modeling,the SAH+AA group was given AA solution(30 mg/kg)by gavage.Neurobehavioral changes were assessed by foot fault test and modified Garcia score.Western blot assay was used to detect the protein level of glutathione peroxidase 4(GPX4)in brain tissue.ELISA was used to detect the concentrations of glutathione(GSH)and malondialdehyde(MDA).Fluoro Jade B(FJB)staining was used to detect the neuronal death.Results Compared with the sham1 group,the SAH+vehicle group showed a significant increase in the proportion of empty steps and a significant decrease in the modified Garcia score,a significant decrease in GPX4 protein levels,a significant increase in MDA concentration(P<0.05),a decrease in GSH concentration(P<0.01)and a significant increase in the number of dead neurons(P<0.05).Compared with the SAH+vehicle group,a significant decrease in the proportion of empty steps,a significant increase in the modified Garcia score,a significant increase in GPX4 protein level,a significant decrease in MDA concentration,a significant increase in GSH concentration(P<0.05)and a significant decrease in the number of dead neurons in the SAH+AA group(P<0.05).Conclusion AA may reduce brain injury after SAH in rats by inhibiting lipid peroxidation.
ABSTRACT
Objective To explore the feasibility of quantitative EEG parameters for prognostic prediction of patients with severe aneurysmal subarachnoid hemorrhage(SaSAH)90 d after the onset of the disease.Methods Patients with SaSAH admitted to the Neurosurgical Intensive Care Unit(NSICU)of Henan Provincial People's Hospital from September 2022 to September 2023 were prospectively consecutively enrolled,and baseline data were collected,including age,gender,medical history(hypertension,diabetes mellitus,coronary artery disease,and stroke),history of smoking,history of drinking,location of aneurysm(anterior circulation,posterior circulation),surgical modality(craniotomy,interventional surgery,hybrid surgery),Hunt-Hess classification,Glasgow coma scale(GCS)score,acute physiology and chronic health status scoring system Ⅱ(APACHE Ⅱ)score,subarachnoid hemorrhage early brain edema score(SEBES),first randomized blood glucose level after admission to NSICU,lactate level,and duration of NSICU stay.Quantitative EEG monitoring was performed in all patients within 48 h after admission to the NSICU,and amplitude-integrated electroencephalogram(aEEG)upper and lower boundaries,95%spectral edge frequency(SEF95),α change,(δ+θ)to(α+β)power ratio(DTABR),brain symmetry index(BSI),and spectral entropy were collected.Based on modified Rankin scale(mRS)scores 90 d after onset,patients were categorized into good prognosis(mRS score 2 points)and poor prognosis(mRS score 3-6 points)groups.Spearman rank correlation was used to analyze the correlation between quantitative EEG parameters and mRS scores in SaSAH patients.Multifactorial Logistic regression analysis was used to screen for correlates of poor prognosis,and receiver operating characteristic(ROC)curves were plotted to evaluate the efficacy of each index in predicting patients'poor prognosis.Results(1)A total of 72 patients with SaSAH were included,with 47 in the poor prognosis group and 25 in the good prognosis group,and the poor prognosis rate at 90 d after the onset was 65.3%.There was no statistically significant difference between the two groups in terms of gender,age,hypertension,diabetes mellitus,coronary artery disease,history of stroke,history of smoking,history of drinking,location of aneurysm,surgical modality,lactate level,and length of hospitalization in the NSICU(all P>0.05);the differences between the Hunt-Hess grading,SEBES,and random blood glucose were statistically significant upon comparison(all P<0.05).Compared with the good prognosis group,the changes of aEEG upper and lower boundary,SEF95,α change and spectral entropy were lower in the poor prognosis group,but DTABR and BSI were higher(all P<0.05).(2)Spearman rank correlation analysis showed that the upper border of aEEG(r=-0.41,P<0.01),lower border of aEEG(r=-0.54,P<0.01),SEF95(r=-0.46,P<0.01),α change(r=-0.53,P<0.01)and spectral entropy(r=-0.39,P<0.01)were negatively correlated with the mRS scores of SaSAH patients,and DTABR(r=0.52,P<0.01)and BSI(r=0.33,P<0.01)were positively correlated with poor prognosis of SaSAH patients.(3)The results of multifactorial Logistic regression analysis showed that Hunt-Hess grading(level Ⅳ vs.Ⅲ:OR,1.203,95%CI 1.005-1.441,P=0.044;level V vs.Ⅲ:OR,1.661,95%CI 1.109-2.487,P=0.014),SEBES(OR,1.647,95%CI 1.050-2.586;P=0.030),aEEG lower border(OR,0.687,95%CI 0.496-0.953l;P=0.024),SEF95(OR,0.436,95%CI0.202-0.937;P=0.034),α change(OR,0.368,95%CI0.189-0.717;P=0.003),DTABR(OR,1.324,95%CI 1.064-1.649;P=0.012),and BSI(OR,1.513,95%CI 1.026-2.231;P=0.036)were influencing factors of poor prognosis in SaSAH patients.ROC curve analysis showed that all of the above seven indicators had a certain predictive value for poor prognosis in SaSAH patients,among which the area under the curve of DTABR was the highest as 0.862(95%CI 0.761-0.932),with sensitivity 85.11%and specificity 80.00%.Conclusion Quantitative EEG parameters aEEG lower border,SEF95,α change,DTABR,and BSI may have certain predictive value for the short-term prognosis of SaSAH patients,which needs to be further confirmed in future multi-center large-sample studies.
ABSTRACT
In recent years,there have been active studies on intracranial hemorrhage associated with hematological malignancies,but the understanding of subarachnoid hemorrhage associated with hematological malignancies is still insufficient.We retrieve from PubMed and China National Knowledge Infrastructure(NCKI),and describes the understanding of hematological malignant tumor related subarachnoid hemorrhage.This article summarizes the clinical characteristics and possible pathogenesis of subarachnoid hemorrhage associated with hematological malignancies.At present,there is a lack of effective prevention and treatment measures for hematological malignant tumor-related subarachnoid hemorrhage,which mainly focuses on the active treatment of the primary disease while saving time for the treatment of complications,and the mortality is high.
ABSTRACT
Abstract Background There is very few data regarding homocysteine's influence on the formation and rupture of intracranial aneurysms. Objective To compare homocysteine levels between patients with ruptured and unruptured intracranial aneurysms, and to evaluate possible influences of this molecule on vasospasm and functional outcomes. Methods This is a retrospective, case-control study. We evaluated homocysteinemia differences between patients with ruptured and unruptured aneurysms; and the association of homocysteine levels with vasospasm and functional outcomes. Logistic regressions were performed. Results A total of 348 participants were included: 114 (32.8%) with previous aneurysm rupture and 234 (67.2%) with unruptured aneurysms. Median homocysteine was 10.75μmol/L (IQR = 4.59) in patients with ruptured aneurysms and 11.5μmol/L (IQR = 5.84) in patients with unruptured aneurysms. No significant association was detected between homocysteine levels and rupture status (OR = 0.99, 95% CI = 0.96-1.04). Neither mild (>15μmol/L; OR = 1.25, 95% CI 0.32-4.12) nor moderate (>30μmol/L; OR = 1.0, 95% CI = 0.54-1.81) hyperhomocysteinemia demonstrated significant correlations with ruptured aneurysms. Neither univariate (OR = 0.86; 95% CI 0.71-1.0) nor multivariable age-adjusted (OR = 0.91; 95% CI = 0.75-1.05) models evidenced an association between homocysteine levels and vasospasm. Homocysteinemia did not influence excellent functional outcomes at 6 months (mRS≤1) (OR = 1.04; 95% CI = 0.94-1.16). Conclusion There were no differences regarding homocysteinemia between patients with ruptured and unruptured intracranial aneurysms. In patients with ruptured aneurysms, homocysteinemia was not associated with vasospasm or functional outcomes.
RESUMO Antecedentes Existem poucos dados sobre a influência da homocisteína na formação e rotura de aneurismas intracranianos (AI). Objetivo Comparar os níveis de homocisteína entre pacientes com AI rotos e não rotos e influências no vasoespasmo e resultados funcionais. Métodos Estudo caso-controle, que avaliou as diferenças de homocisteinemia entre pacientes com aneurismas rotos e não rotos, além da associação entre níveis de homocisteína, vasoespasmo e estado funcional. Regressões logísticas foram realizadas. Resultados Um total de 348 participantes foram incluídos: 114 (32,8%) com aneurismas rotos e 234 (67,2%) não rotos. A homocisteína mediana foi de 10,75μmol/L (IQR = 4,59) nos rotos e 11,5μmol/L (IQR = 5,84) nos não rotos. Não houve associação significativa entre os níveis de homocisteína e o status de ruptura (OR = 0,99, 95% CI = 0,96-1,04). Nem a hiperhomocisteinemia leve (>15μmol/L; OR = 1,25, 95% CI = 0,32-4,12) nem a moderada (>30μmol/L; OR = 1,0, 95% CI = 0,54-1,81) mostraram correlações significativas com aneurismas rotos. Modelos univariados (OR = 0,86; 95% CI = 0,71-1,0) e multivariados ajustados por idade (OR = 0,91; 95% CI = 0,75-1,05) não evidenciaram associação entre homocisteína e vasoespasmo. A homocisteinemia não influenciou resultados funcionais excelentes em seis meses (mRS ≤ 1) (OR = 1,04; 95% CI = 0,94-1,16). Conclusão Não houve diferenças em relação à homocisteinemia entre pacientes com aneurismas intracranianos rotos e não rotos. Em pacientes com aneurismas rotos, a homocisteinemia não foi associada ao vasoespasmo ou resultados funcionais.
ABSTRACT
Objective The present study aims to assess and compare the prognostic value of these two scales for predicting mortality. Method We reviewed 172 patients with aneurysmal subarachnoid hemorrhage, who were followed-up for 6 months. The Fisher and modified Fisher scales were evaluated for the prediction of mortality using logistic regressions. Results The Fisher scale was associated with mortality (odds ratio [OR]: 2; 95% confidence interval [CI]: 1.094.05) in the multivariate analysis. The modified Fisher scale was not associated with mortality in the multivariate analysis (OR: 1.39; 95% CI: 0.92.29), nor in the univariate analysis (OR: 1.24; 95%CI: 0.871.86). There was no significant association between Fisher score and unfavorable functional outcomes (mRS > 2) in the univariate analysis (OR: 1.33; 95%CI: 0.921.92), nor in the multivariate analysis (OR: 1.37; 95%CI: 0.922.05). There was no significant association between modified Fisher scores and unfavorable functional outcomes in the univariate analysis (OR: 1.16; 95%CI: 0.881.52). There was also no significant association in the multivariate analysis (OR: 1.18; 95%CI: 0.881.57). Conclusion Only the Fisher scale was associated with mortality. Neither of the two scales was associated with unfavorable functional outcomes (mRS > 2).
Objetivo O presente estudo tem como objetivo avaliar e comparar o valor prognós tico dessas duas escalas para predizer mortalidade. Método Revisamos 172 pacientes com hemorragia subaracnóidea aneurismática, acompanhados por 6 meses. As escalas de Fisher e modificada de Fisher foram avaliadas para a previsão de mortalidade usando regressões logísticas. Resultados A escala de Fisher foi associada à mortalidade (odds ratio [OR]: 2; intervalo de confiança [IC] 95%: 1.094.05) na análise multivariada. A escala Fisher modificada não foi associada à mortalidade na análise multivariada (OR: 1.39; IC95%: 0.92.29), nem na análise univariada (OR: 1.24; IC95%: 0.871.86). Não houve associação significativa entre o escore de Fisher e resultados funcionais desfavoráveis (mRS > 2) na análise univariada (OR: 1.33; IC95%: 0.921.92), nem na análise multivariada (OR: 1.37; IC95%: 0.922.05). Não houve associação significativa entre os escores modificados de Fisher e resultados funcionais desfavoráveis na análise univariada (OR: 1.16; IC95%: 0.881.52). Também não houve associação significativa na análise multivariada (OR: 1.18; IC95%: 0.881.57). Conclusão Apenas a escala de Fisher foi associada à mortalidade. Nenhuma das duas escalas foi associada a resultados funcionais desfavoráveis (mRS > 2).
ABSTRACT
Introducción: si bien varios estudios han abordado la comparación entre el tratamiento endovascular y el clipado quirúrgico de aneurismas rotos, no existe aún evidencia firme respecto a la utilización de una u otra técnica en términos de seguridad y mejor pronóstico. El objetivo de este trabajo es analizar las distintas modalidades de tratamiento de la hemorragia subaracnoidea (HSA) implementadas en Uruguay y su impacto sobre la curación del aneurisma y el pronóstico de los pacientes. Material y método: estudio prospectivo y multicéntrico que incluyó a todos los pacientes mayores de 18 años que fueron asistidos por HSA espontánea aneurismática en Uruguay entre el 1 de noviembre de 2019 y el 31 de octubre de 2020. Fueron relevadas las características clínico-epidemiológicas y comorbilidades al momento del diagnóstico, el tipo de tratamiento recibido y variables de evolución clínica durante los siguientes seis meses. Los datos fueron procesados a través del software estadístico Statistical Package for Social Sciences (SPSS) y el nivel de significación utilizado en los test fue de 5%. Debido al carácter multicéntrico y nacional del estudio, debió ser sometido a evaluación por todos los comités de ética de las instituciones de salud participantes. Resultados: se observó un total de 211 casos en el período evaluado. La media de edad fue de 57 años con predominancia del sexo femenino (75%). En el 74% de los casos fue indicado algún tipo de tratamiento específico (43% cirugía abierta y 31% terapia endovascular), mientras al resto de los pacientes no se les pudo tratar el aneurisma por su grave situación neurológica; 52 pacientes tuvieron complicaciones vinculadas al tratamiento recibido, observándose una mayor proporción de estas en el caso de la cirugía abierta respecto a la terapia endovascular (42% vs 21,5%; p=0,008). Conclusiones: se observó una mayor tasa de complicaciones en el tratamiento quirúrgico, sin impacto en la morbimortalidad. De los factores predictores independientes de mala evolución clínica encontrados, el único vinculado al tipo de tratamiento fue la presencia de isquemia extensa.
Introduction: While several studies have addressed the comparison between endovascular treatment and surgical clipping of ruptured aneurysms, there is still no definitive evidence regarding the use of one or the other in terms of safety and improved prognosis. The objective of this study is to analyze the various modalities of subarachnoid hemorrhage (SAH) treatment implemented in Uruguay and their impact on aneurysm resolution and patient prognosis. Method: This is a prospective, multicenter study that includes all patients over 18 years of age who were treated for spontaneous aneurysmal subarachnoid hemorrhage in Uruguay between November 1, 2019, and October 31, 2020. We collected and examined clinical-epidemiological characteristics and comorbidities at the time of diagnosis, the type of treatment received, and clinical outcome variables over the following 6 months. The data were analysed using the Statistical Package for Social Sciences (SPSS) software, and a significance level of 5% was applied in the tests. Due to the multicenter and national nature of the study, it had to be submitted for evaluation to all the Ethics Committees of the participating healthcare institutions. Results: A total of 211 cases were observed during the evaluated period. The mean age was 57 years with a predominance of females (75%). In 74% of the cases, some form of specific treatment was recommended (43% open surgery and 31% endovascular therapy), while the remaining patients could not undergo aneurysm treatment due to their severe neurological condition. 52 patients experienced complications related to the treatment received, with a higher proportion of these in the case of open surgery compared to endovascular therapy (42% vs. 21,5%; p=0,008). Conclusions: A higher rate of complications was observed in the surgical treatment, with no impact on morbidity and mortality. Among the independent predictors of poor clinical outcomes identified, the only one related to the type of treatment was the presence of extensive ischemia.
As campanhas de prevenção e promoção da saúde, bem como os avanços na medidas terapêuticas voltadas para pacientes neurocríticos conseguiram reduzir a incidência de pacientes com lesão cerebral aguda que evoluem para morte encefálica (ME). No entanto, na maioria dos países latino-americanos, os órgãos que podem ser perfundidos adequados para transplante (TX) vêm de doadores falecidos em ME. A doação em assistolia e em particular a doação em assistolia controlada (DAC), é uma opção aceita e válida para a obtenção de órgãos, o que contribuiria para a redução das listas de espera para transplantes. Durante o processo DAC, são aplicados conceitos com forte cunho bioético, que são fundamentais na o momento da tomada de decisão. Este artigo tem como objetivo analisar esses conceitos, com o objetivo de oferecer ferramentas válidas à equipe de saúde, para os processos em que há deliberação moral como ocorre na doação de órgãos em assistolia controlada considerada parte integrante dos cuidados de fim de vida.

To describe the topographic and morpho-structural features of aneurysms in our country. Methods. All patients over 18 years old with a diagnosis of SAH, who consulted to a healthcare center in the country between 11/01/2019 and 10/31/2020, were included in the study. The clinical-epidemiological characteristics and comorbidities at the time of diagnosis, the type of treatment received and clinical evolution variables during the following 6 months were collected. The significance level of evidence used in the tests was 5%. Due to the multicenter and national nature of the study, it had to be subjected to an evaluation by all the Ethics Committees of the participating health institutions, and by the National Research Ethics Commission. Results. A total of 211 cases were observed in the evaluated period. The average age was 57 years with a predominance of the female sex (75%). In 82% of cases, the vascular study used was CT angiography. The most common aneurysmal topography was anterior communicating artery (27.5%), middle cerebral artery (27%), and posterior communicating artery (23%). 27% suffered multiple aneurysms. In 74% of cases, some type of specific treatment was indicated (43% open surgery and 31% endovascular therapy). Conclusions. This work provides the first figures on the topography of ruptured aneurysms in Uruguay, being this comparable to what is described in the international literature
ABSTRACT
El estudio tuvo como objetivo determinar los factores predictivos de muerte (en los primeros 21 días) en pacientes con hemorragia subaracnoidea espontánea; para esto se realizó un estudio observacional, descriptivo-correlacional, que incluyó a 79 pacientes con hemorragia subaracnoidea espontánea entre 2016 y 2021. Se determinó la letalidad por la enfermedad y su relación con diversas variables, para lo cual se realizó análisis bivariado y multivariado (regresión logística); se utilizó como estadígrafo el Odds Ratio y su intervalo de confianza. Entre los principales resultados se encuentran los siguientes: fallecieron 29 pacientes (36,7%). La letalidad fue superior en adultos mayores (40% vs 33%, no significativo), en el sexo femenino (43% vs 29%, no significativo) y en los pacientes que ingresaron en las primeras 48 horas del diagnóstico (43% vs 7%, OR 9,8[1,2;79,7]); también en quienes no pudo ser identificada la causa del sangramiento (64%), y en la presentación clínica con predominio de alteraciones del estado de conciencia (OR 3,3[1,03;10,5]). En las escalas clínica e imagenológicas utilizadas se constató un incremento progresivo de la letalidad de los grados bajos a los altos (Hunt y Hess: OR 13,6[4,3;43,2]; Fisher: OR 14,4[1,8;115,3]). Como conclusiones de la investigación, la letalidad a los 21 días en la serie estudiada se considera elevada, y estuvo asociada a la presentación clínica con predominio de alteraciones en el estado de conciencia, la mayor intensidad del sangramiento inicial (Fisher III-IV), la ocurrencia de complicaciones neurológicas y la infección respiratoria sobreañadida. Se comprueba la importancia del resangrado en la ocurrencia de muerte, así como la condición de predictor de fallecimiento de la escala de Hunt y Hess.
The study aimed to determine the predictors of death (in the first 21 days) in patients with spontaneous subarachnoid hemorrhage; for this, an observational, descriptive-correlational study was carried out, which included 79 patients with spontaneous subarachnoid hemorrhage between 2016 and 2021. Fatality due to the disease and its relationship with various variables were determined, for which bivariate and multivariate analysis (logistic regression) was performed; The Odds Ratio and its confidence interval were used as statisticians. Among the main results are the following: 29 patients (36.7%) died. Mortality was higher in older adults (40% vs 33%, not significant), in females (43% vs 29%, not significant) and in patients admitted within the first 48 hours of diagnosis (43% vs 7%, OR 9.8[1.2;79.7]); also in whom the cause of the bleeding could not be identified (64%), and in the clinical presentation with a predominance of alterations in the state of consciousness (OR 3.3[1.03;10.5]). In the clinical and imaging scales used, a progressive increase in lethality from low to high grades was found (Hunt and Hess: OR 13.6[4.3;43.2]; Fisher: OR 14.4[1.8;115.3]). As conclusions of the investigation, the lethality at 21 days in the series studied is considered high, and was associated with the clinical presentation with a predominance of alterations in the state of consciousness, the greater intensity of the initial bleeding (Fisher III-IV), the occurrence of neurological complications and the superimposed respiratory infection. The importance of rebleeding in the occurrence of death is verified, as well as the condition of death predictor of the Hunt and Hess scale.

ABSTRACT Objective: To determine the prevalence of sonographic vasospasm and delayed ischemic deficit in patients with aneurysmal subarachnoid hemorrhage, to evaluate the correlation between different tomographic scales and these complications, and to study prognostic factors in this group of patients. Methods: This was a prospective study of patients admitted to the intensive care unit with a diagnosis of aneurysmal subarachnoid hemorrhage. The prevalence of sonographic vasospasm and radiological delayed cerebral ischemia was analyzed, as was the correlation between different tomographic scales and these complications. Results: A total of 57 patients were studied. Sixty percent of the patients developed sonographic vasospasm, which was significantly associated with delayed cerebral ischemia and mortality. The Claassen and Hijdra scales were better correlated with the development of cerebral vasospasm (areas under the curve of 0.78 and 0.68) than was Fisher's scale (0.62). Thirty-two patients (56.1%) developed cerebral infarction on CT; the significantly associated factors were poor clinical grade at admission (p = 0.04), sonographic vasospasm (p = 0.008) and severity of vasospasm (p = 0.015). Only the semiquantitative Hijdra scale was significantly correlated with the development of radiological delayed cerebral ischemia (p = 0.009). The patients who presented cerebral infarction had worse neurological evolution and higher mortality. Conclusion: This is the first study in our environment on the subject. The Claassen and Hijdra tomographic scales showed better prognostic performance than the Fisher scale for the development of cerebral vasospasm. The finding of sonographic vasospasm could be a noninvasive criterion for the early detection of delayed cerebral ischemia and neurological deterioration in patients with aneurysmal subarachnoid hemorrhage.
RESUMO Objetivo: Determinar la prevalencia de vasoespasmo sonográfico y déficit isquémico diferido en pacientes con hemorragia subaracnoidea aneurismática, evaluar la correlación entre las diferentes escalas tomográficas con dichas complicaciones, así como estudiar los factores pronósticos en este grupo de pacientes. Métodos: Estudio prospectivo de pacientes ingresados a la unidad de cuidados intensivos con diagnóstico de hemorragia subaracnoidea aneurismática. Se analizó la prevalencia de vasoespasmo sonográfico e isquemia cerebral diferida radiológica, así como la correlación entre diferentes escalas tomográficas con dichas complicaciones. Resultados: Se estudiaron 57 pacientes. El 60% de los pacientes desarrollaron vasoespasmo sonográfico, el cual se asoció significativamente con isquemia cerebral diferida y mortalidad. Las escalas de Claassen y de Hijdra tuvieron una mejor correlación con el desarrollo de vasoespasmo cerebral (área bajo la curva de 0,78 y 0,68) que la de Fisher (0,62). Treinta y dos pacientes (56,1%) desarrollaron infarto cerebral en la TC, siendo los factores que se asociaron en forma estadísticamente significativa al mismo: pobre grado clínico al ingreso (p = 0,04), vasoespasmo sonográfico (p = 0,008) y severidad del vasoespasmo (p = 0,015). Solamente la escala semicuantitativa de Hijdra se correlacionó significativamente con el desarrollo de isquemia cerebral diferida radiológica (p = 0,009). Los pacientes que presentaron infarto cerebral tuvieron peor evolución neurológica y mayor mortalidad. Conclusion: Se presenta el primer estudio en nuestro medio sobre el tema. Las escalas tomográficas de Claassen y Hijdra presentaron un mejor rendimiento pronóstico que la de Fisher para desarrollo de vasoespasmo cerebral. El hallazgo de vasoespasmo sonográfico podría ser un criterio no invasivo de detección temprana de isquemia cerebral diferida y peoría neurológica en los pacientes con hemorragia subaracnoidea aneurismática.
ABSTRACT
Abstract Background Subarachnoid hemorrhage (SAH) prognosis remains poor. Vasospasm mechanism might be associated with inflammation. Neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been studied as inflammation markers and prognostic predictors. Objective We aimed to investigate NLR and PLR in admission as predictors of angiographic vasospasm and functional outcome at 6 months. Methods This cohort study included consecutive aneurysmal SAH patients admitted to a tertiary center. Complete blood count was recorded at admission before treatment. White blood cell count, neutrophil count, lymphocyte count, platelet count, NLR, and PLR were collected as independent variables. Vasospasm occurrence-modified Rankin scale (mRS), Glasgow outcome scale (GOS), and Hunt-Hess score at admission and at 6 months were recorded as dependent variables. Multivariable logistic regression models were used to adjust for potential confounding and to assess the independent prognostic value of NLR and PLR at admission. Results A total of 74.1% of the patients were female, with mean age of 55.6 ± 12.4 years. At admission, the median Hunt-Hess score was 2 (interquartile range [IQR] 1), and the median mFisher was 3 (IQR 1). Microsurgical clipping was the treatment for 66.2% of the patients. Angiographic vasospasm incidence was 16.5%. At 6 months, the median GOS was 4 (IQR 0.75), and the median mRS was 3 (IQR 1.5). Twenty-one patients (15.1%) died. Neutrophil-to-lymphocyte ratio and PLR levels did not differ between favorable and unfavorable (mRS > 2 or GOS < 4) functional outcomes. No variables were significantly associated with angiographic vasospasm. Conclusion Admission NLR and PLR presented no value for prediction of functional outcome or angiographic vasospasm risk. Further research is needed in this field.
Resumo Antecedentes O prognóstico da hemorragia subaracnoidea (HSA) permanece ruim. Vasoespasmo pode estar associado à inflamação. Razões neutrófilo-linfócito (NLR) e plaqueta-linfócito (PLR) têm sido estudadas como marcadores de inflamação e prognóstico. Objetivo Investigar NLR e PLR na admissão como preditores de vasoespasmo angiográfico e desfecho aos 6 meses. Métodos Este estudo de coorte incluiu pacientes consecutivos com HSA aneurismática de um centro terciário. Contagem de leucócitos, neutrófilos, linfócitos e plaquetas, proporção de neutrófilos para linfócitos e de plaquetas para linfócitos foram coletados como variáveis independentes. Ocorrência de vasoespasmo, escala de Rankin modificada, escala de desfecho de Glasgow e o escore de Hunt-Hess na admissão e 6 meses após a mesma foram registradas como variáveis dependentes. Modelos de regressão logística multivariável foram usados para ajustar potenciais fatores de confusão e avaliar valor prognóstico independente de NLR e PLR. Resultados Um total de 74,1% pacientes eram do sexo feminino, com idade média de 55,6 ± 12,4 anos. Na admissão, a pontuação média de Hunt-Hess foi de 2 (IQR 1) e a mediana de mFisher foi de 3 (IQR 1). Clipagem microcirúrgica foi o tratamento escolhido para 66,2% dos pacientes. A incidência de vasoespasmo angiográfico foi de 16,5%. Aos 6 meses, a escala de desfecho de Glasgow mediana era 4 (IQR 0,75) e a escala de Rankin modificada mediana era 3 (IQR 1,5). Vinte e um pacientes (15,1%) morreram. Os níveis de NLR e PLR não diferiram entre resultados funcionais favoráveis e desfavoráveis (mRS > 2 ou GOS < 4). Nenhuma variável foi significativamente associada ao vasoespasmo angiográfico. Conclusão Razão neutrófilo-linfócito e a PLR não apresentaram valor preditivo de desfecho funcional ou risco de vasoespasmo angiográfico. Mais pesquisas são necessárias neste campo.
ABSTRACT
Fundamento: la importancia sanitaria de la hemorragia subaracnoidea espontánea, como problema de salud, es un hecho reconocido. Objetivo determinar el comportamiento de algunos indicadores relacionados con la asistencia médica a pacientes con hemorragia subaracnoidea espontánea, en el contexto provincial. Métodos estudio observacional, descriptivo-correlacional y retrospectivo, de 96 pacientes con hemorragia subaracnoidea espontánea entre 2016 y 2021. Se analizó el comportamiento de indicadores seleccionados, en su relación con diversas variables. En el análisis estadístico se utilizó como estadígrafo el Odds Ratio y su intervalo de confianza. Resultados el 22 % de los pacientes fue diagnosticado pasadas las primeras 48 horas del inicio de los síntomas, mientras que 13 enfermos (14 %) requirieron más de una asistencia para el diagnóstico. La ocurrencia de diagnóstico tardío cuando no se identificó el sangramiento en la primera consulta fue significativa (OR 21,8[5,1;91,8]). Doce pacientes fueron admitidos fuera de unidades especializadas; esta situación se observó más en pacientes menores de 60 años (21% vs 4 %; OR 5,7[1,1;27,9]), y en quienes el diagnóstico se realizó después de las 48 horas del inicio de las manifestaciones (29 % vs 8 %; OR 4,6[1,3;16,2]). De los 35 pacientes trasladados a otra institución para tratamiento neuroquirúrgico solo cuatro (12 %) fueron evacuados en las primeras 72 horas. Conclusiones se identifican brechas en la atención al paciente con hemorragia subaracnoidea en el contexto provincial; se destacan el ingreso de enfermos fuera de unidades especializadas y el traslado tardío a instituciones con servicio de cirugía neurovascular.
Background: the spontaneous subarachnoid hemorrhage's health importance, it's recognized as a health problem. Objective: to determine the behavior of some indicators related to medical care for patients with spontaneous subarachnoid hemorrhage, in the provincial context. Methods: Observational, descriptive-correlational and retrospective study of 96 patients with spontaneous subarachnoid hemorrhage between 2016 and 2021. The behavior of selected indicators was analyzed in relation to various variables. In the statistical analysis, the Odds Ratio and its confidence interval were used as statisticians. Results: 22% of the patients were diagnosed after the first 48 hours after the onset of symptoms, while 13 patients (14%) required more than one assistance for diagnosis. The occurrence of late diagnosis when bleeding was not identified at the first visit was significant (OR 21.8[5.1;91.8]). Twelve patients were admitted outside of specialized units; this situation was observed more in patients under 60 years of age (21% vs 4%; OR 5.7[1.1;27.9]), and in whom the diagnosis was made 48 hours after the onset of manifestations (29% vs 8%; OR 4.6[1.3;16.2]). Of the 35 patients transferred to another institution for neurosurgical treatment, only four (12%) were evacuated in the first 72 hours. Conclusions: gaps are identified in the patients' care with subarachnoid hemorrhage in the provincial context; The admission of patients outside specialized units and the late transfer to institutions with neurovascular surgery service stand out.
ABSTRACT
Objetivo: Determinar los resultados clínicos y angiográficos en pacientes con aneurismas intracraneales múltiples tratados endovascularmente en una única sesión. Materiales y Métodos: Se incluyó a todos los pacientes mayores de 18 años con aneurismas múltiples (≥2), rotos o no rotos, tratados con terapia endovascular en una única sesión entre 2019 y 2021. Se recolectaron los datos clínicos y angiográficos. Se determinó la tasa de oclusión inmediata y del seguimiento. La escala de Rankin modificado se usó para valorar el resultado clínico. Resultados: Se trataron 25 pacientes, de los cuales 14 se presentaron con hemorragia subaracnoidea. Se diagnosticaron un total de 78 aneurismas, de los cuales 59 aneurismas fueron tratados. La localización más frecuente fue el segmento oftálmico. La altura máxima promedio fue de 5.2mm, lo cual tuvo diferencia estadística significativa con el estado de ruptura (p ≤ 0.02). El principal tipo de tratamiento endovascular fue la técnica de remodeling en el 39 % de casos. El Raymond Roy inmediato fue I en el 60 % y IIIa en el 35 % de casos. La tasa de complicaciones fue del 24 % y de mortalidad fue del 8 %. Conclusiones: El tratamiento endovascular en una única sesión es una opción efectiva y segura en casos de aneurismas intracraneales múltiples en nuestra institución con tasa de oclusión y complicaciones aceptable.
Objective: To determine clinical and angiographical outcomes in patients with multiple intracranial aneurysms who underwent endovascular therapy in a single session. Materials and Methods: Patients older than 18 years with multiple (≥2) ruptured or non-ruptured aneurysms were included, and all of them underwent endovascular therapy in a single session between 2019 and 2021. Clinical and angiographic data was collected. Immediate occlusion and follow-up data were collected. Rankin modified scale was used for assessing clinical outcomes. Results: Twenty-five patients were treated, and fourteen had subarachnoid hemorrhage. Seventy-eight aneurysms were diagnosed, and 59 of them were treated. The most frequent location was at the ophthalmic segment. Maximum average height was 5.2- mm, which showed significant statistical difference with a ruptured condition (p≤0.02). The main modality for endovascular therapy was the remodeling technique, which was used in 39% of all cases. Immediate Raymond Roy staging was I in 60% of all cases, and IIIa in 35% of all cases. Complication rate was 24%, and mortality rate was 8%. Conclusions: Single session endovascular therapy is an effective and safe option for cases of multiple intracranial aneurysms in our institution. Occlusion and complication rates were acceptable.
