ABSTRACT
ABSTRACT BACKGROUND: Embolization is a promising treatment strategy for cerebral arteriovenous malformations (AVMs). However, consensus regarding the main complications or long-term outcomes of embolization in AVMs remains lacking. OBJECTIVE: To characterize the most prevalent complications and long-term outcomes in patients with AVM undergoing therapeutic embolization. DESIGN AND SETTING: This systematic review was conducted at the Federal University of Alagoas, Arapiraca, Brazil. METHODS: This systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses criteria. Data were obtained from MEDLINE, PubMed, LILACS, and SciELO databases, which included the epidemiological profile of the population, characteristics of the proposed therapy, complications (hemorrhagic events and neurological deficits), and long-term outcomes (modified Rankin scale pre- and post-treatment, AVM recanalization, complete obliteration, and deaths). RESULTS: Overall, the analysis included 34 articles (2,799 patients). Grade III Spetzler-Martin AVMs were observed in 34.2% of cases. Notably, 39.3% of patients underwent embolization combined with radiosurgery. The most frequently reported long-term complication was hemorrhage, which occurred in 8.7% of patients at a mean follow-up period of 58.6 months. Further, 6.3% of patients exhibited neurological deficits after an average of 34.7 months. Complete obliteration was achieved in 51.4% of the cases after a mean period of 36 months. Recanalization of AVMs was observed in 3.5% of patients. Long-term death occurred in 4.0% of patients. CONCLUSION: Embolization of AVMs is an increasingly safe strategy with low long-term complications and satisfactory outcomes, especially in patients who have undergone combination therapies.

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 observe the value of the ratio of cerebral hyperdensities(PCHD)/venous sinus maximum density for predicting hemorrhagic transformation(HT)after endovascular treatment(EVT)in patients with acute ischemic stroke(AIS).Methods Data of 79 AIS patients with PCHD immediately after EVT were retrospectively analyzed.The patients were divided into HT group(n=41)or non-HT group(n=38)based on the presence of HT or not.Clinical data and CT parameters were compared between groups.The value of the ratio of PCHD/venous sinus maximum density for predicting HT was evaluated.Results The maximum density of PCHD and the ratio of PCHD/venous sinus maximum density in HT group were both higher than those in non-HT group(both P<0.001).Taken 87 HU as the best cut-off value of the maximum density of PCHD,the sensitivity,specificity and area under the curve(AUC)for predicting HT after EVT in AIS patients was 90.24%,71.05%and 0.79,respectively.Taken 0.94 as the best cut-off value of the ratio of PCHD/venous sinus maximum density,the sensitivity,specificity and AUC was 97.56%,71.05%and 0.81,respectively.No significant difference of AUC was found between the former and the latter(P>0.05).Conclusion The ratio of PCHD/venous sinus maximum density immediately after EVT could be used to predict HT in AIS patients.
ABSTRACT
Objective Observing the feasibility of acute endovascular treatment for patients with symptomatic anterior intracranial atherosclerotic severe stenosis.Method From Jun 2019 to Jun 2023,30 symptomatic anterior intracranial atherosclerotic severe stenosis cases were retrospectively collected in the Guangdong Hospital of Traditional Chinese Medicine to evaluate the risk stratification score and explore the safety and effectiveness of acute(≤72.0h)endovascular treatment.Endovascular treatment includes balloon dilation+self-expanding stent placement,balloon-mounted stent placement,and balloon dilation.From the clinical experience,the risk stratification score was based on the ABCD3-I score for transient ischemic attacks(TIA)and additional evaluation of cerebral watershed infarction to identify the risk of stroke progression or recurrence in acute stage of symptomatic intracranial artery stenosis.The score of 0-3 was defined as low-risk,4-7 as medium risk,and 8-13 as high-risk.The successful revascularization of blood flow is determined based on the residual stenosis≤50%and the extended thrombolysis in cerebral infarction(eTICI)>2c.The information of patient receiving endovascular treatment was recorded,including age,sex,risk factors of cerebrovascular disease(hypertension,diabetes,hyperlipidemia,hyperhomocysteinemia,drinking history,smoking history),onset data(time from onset to endovascular treatment,symptoms,progression),diseased vessels,risk stratification score,National Institutes of Health Stroke Scale(NIHSS)score before and 90 days after surgery,modified Rankin scale(mRS)score 90 days after surgery,intraoperative cerebrovascular events(intracranial hemorrhage,occlusion of responsible vessels),and postoperative cerebrovascular events 90 days after surgery(intracranial hemorrhage,cerebral infarction,TIA and in-stent restenosis)and deaths.Results Among 30 patients with symptomatic anterior intracranial atherosclerotic severe stenosis,3 patients were excluded from the time interval between onset and endovascular treatment>72.0 hours,1 patient needed long-term anticoagulant drugs due to other diseases,1 patient lost follow-up,3 patients coexisted with other cardiogenic cerebral embolism diseases,4 patients with non-atherosclerotic arterial stenosis,and 7 patients refused emergency endovascular treatment.11 patients were finally included.(1)All 11 patients were successfully treated with endovascular treatment,and 7 were males;age ranged from 52 to 76 years old,with a median age of 64 years old;there were 9 cases with hypertension,3 cases diabetes,7 cases hyperlipidemia,2 cases hyperhomocysteinemia(only 9cases performed the examination),2cases smoking history,1 case drinking history;time from onset to endovascular treatment is 4.0-72.0 h,with a median time of 12.0 h;there were 3 and 8 cases of infarction in the left and right hemispheres,respectively,with 4,3,and 2 cases accompanied with anterior-posterior watershed,medial watershed,and anlerior-medial-posterior watershed infarctions,and 1 case accompanied by posterior-medial,anterior-medial watershed infarctions.(2)Among the 1 1 patients,the risk stratification score was 10-13 points,with a median score of 11 points;preoperative NIHSS score ranged 0-11 points,with a median score of 7 points.(3)Among the 1 1 patients,10 lesions located in the middle cerebral artery and 1 in the C7 segment of the internal carotid artery;the preoperative stenosis rate was 70%to 99%,with a median stenosis rate of 86%;preoperative eTICI grading was 2a in 7 cases and 2b50 in 4 cases(with slow distal blood flow);9 cases received balloon dilation and self-expanding stent placement,1 case received balloon-mounted stent placement,and 1 case received balloon dilation treatment;the postoperative stenosis rate is 10%to 20%,with a median stenosis rate of 15%;there were 3 cases with postoperative eTICI grade 2c and 8 cases with grade 3.(4)Among the 11 patients,one experienced intracranial hemorrhage on the first day after surgery and one had a new cerebral infarction on the third day after surgery.Eight patients were followed up by imaging 90days after surgery,demonstrating 2 cases of in-stent restenosis;90 days post-surgery,NIHSS score was 0-20 points,with a median score of 2 points;after 90 days of surgery,the mRS score was 0-4 points,with a median score of 1 point.There were 8 patients with mRS score ≤ 2 and no death events occurred.Conclusions Preliminary analysis shows that acute endovascular treatment for symptomatic anterior intracranial atherosclerotic severe stenosis has certain effectiveness,but the safety needs to be further validated.The screening of high-risk patients using risk stratification scores still requires further exploration through large sample and multicenter studies.
ABSTRACT
Objective To investigate the relationship between omentin-1,aquaporin 4(AQP4),and visinin-like protein 1(VILIP-1)levels and vascular recanalization after emergency endovascular treatment in patients with acute large vessel occlusion stroke(ALVOS)and their combined predictive efficacy.Methods In total,110 patients with ALVOS undergoing emergency endovascular treatment were categorized into a non-reopening group(23 patients)and a reopening group(87 patients)based on whether the blood vessels were re-opened after surgery.Clinical data and omentin-1,AQP4,and VILIP-1 levels were compared between the two groups.Factors influencing postoperative blood vessel reopening were analyzed,and nomograms were drawn to evaluate their predictive performance and calibration.Results Significant differences were observed in the proportion of patients with hypertension;preoperative NIHSS scores;emergency blood glucose;AQP4,VILIP-1,omentin-1,and platelet levels;time from onset to endovascular treatment;preoperative ASPECTS;and proportion of patients undergoing intravenous thrombolysis between the two groups(P<0.05).Preoperative ASPECTS and omentin-1 levels were independent protective factors associated with postoperative vascular recanalization,whereas the time from onset to endovas-cular treatment,preoperative NIHSS scores,and AQP4 and VILIP-1 levels were independent risk factors associated with postoperative vascular recanalization(P<0.05).The C-index of the nomogram for predicting postoperative vascular recanalization was 0.994,and the AUC of the nomogram for predicting postoperative vascular recanalization was 0.994,with a calibration degree of 0.975.Conclusion Omentin-1,AQP4,and VILIP-1 levels are important factors affecting vascular recanalization in patients with ALVOS after emergency endovascular treatment.Clinically,monitoring these levels may help to predict and evaluate early vascular recanalization fol-lowing treatment.
ABSTRACT
Objective:To investigate the safety and efficacy of intravascular intervention in ruptured intracranial vertebral artery dissecting aneurysm (IVADA).Methods:A retrospective analysis was performed; 25 patients with ruptured IVADA (25 aneurysms) admitted to Department of Neurosurgery, First Affiliated Hospital of University of Science and Technology of China from January 2020 to June 2023, were chosen. Aneurysm and parent artery occlusion or stent-assisted spring coil embolization were performed according to location of the aneurysms, degrees of aneurysm immediate embolization were evaluated by Raymond grading, and perioperative adverse events were recorded. The patients were followed up for 6-48 months, and aneurysm recurrence was determined according to DSA results; prognoses were assessed by modified Rankin Scale (mRS), with scores of 0-2 as good prognosis and scores of 3-6 as poor prognosis.Results:All 25 patients had unilateral ruptured IVADA, 10 (40%) received aneurysm and parent artery occlusion (occlusion of dissection segment) and 15 (60%) received stent-assisted embolization. Immediately after surgery, 19 patients (76%) had grading I embolization, 4 (16%) grading II embolization, and 2 (8%) grading III embolization. No aneurysm rupture or stent related thrombosis was observed during procedure; 3 patients (12%) died after procedure, with postoperative rebleeding in 1, postoperative cerebellar infarction with respiratory failure in 1, and severe pneumonia in 1. In the 22 survivals, 18 had good prognosis and 4 had poor prognosis. In the 5 relapsed patients (all accepted stent-assisted embolization), 4 underwent re-intervention, and one with visualization at aneurysm neck was relatively stable on re-examination and accepted regular follow up.Conclusion:Aneurysm and parent artery occlusion can be used for non-dominant vertebral artery aneurysms not involving posterior inferior cerebellar artery, whose recurrence rate is lower than that of stent-assisted coil embolization.
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.

Introducción. Las fístulas durales arteriovenosas del canal del hipogloso (FDCH) son infrecuentes y suelen ser diagnosticadas tardíamente. Habitualmente se presentan con compromiso del par XII aunque pueden presentarse con síntomas diversos. Objetivos. Presentar un caso de FDCH que se presentó con proptosis y ojo rojo tratado por vía endovascular y describir la anatomía asociada. Descripción del caso. Un hombre de 51 años consultó por quemosis, exoftalmo y dolor ocular leve persistente durante un año. Las pruebas de imagen revelaron una lesión en la base del cráneo, sugestiva de malformación arteriovenosa, con drenaje hacia el bulbo yugular derecho y la vena oftálmica superior derecha. Se descartaron otras causas como tumores metastásicos. Intervención. Se realizó tratamiento por vía endovascular. Se utilizó un abordaje combinado arterial y venoso. La embolización arterial se hizo con un agente embolizante líquido de etilen vinil alcohol -logrando una oclusión parcial- y luego se completó la misma por vía venosa con hélices de platino (coils), logrando la oclusión total de la fístula. El paciente se recuperó favorablemente, con mejoría progresiva de los síntomas oculares. Experimentó una leve paresia del nervio XII derecha en el período postoperatorio inmediato, que se trató con corticoides. Fue dado de alta al quinto día. En el seguimiento a los 6 meses, la lesión no mostraba persistencia en las imágenes de resonancia magnética. Conclusión. Se presenta un caso de fístula dural arteriovenosa del canal del hipogloso tratada por vía endovascular con oclusión completa de la misma
Background. Dural arteriovenous fistulas of the hypoglossal canal are infrequent and are usually diagnosed late. They usually present with involvement of the XII cranial nerve, although they can present with various symptoms. Objectives. To present a case of dural arteriovenous fistulas of the hypoglossal canal that presented with proptosis and red eye treated endovascularly and describe the associated anatomy. Description of the case. A 51-year-old man presented with chemosis, exophthalmos, and mild eye pain that had persisted for one year. Imaging tests revealed a lesion at the skull base, suggestive of arteriovenous malformation, with drainage towards the right jugular bulb and the right superior ophthalmic vein. Other causes such as metastatic tumors were ruled out. Surgery. Endovascular embolization was performed to treat the dural arteriovenous fistula. A combined approach using arterial and venous was used. The arterial embolization was done with a liquid embolization agent of ethylene vinyl alcohol -achieving partial occlusion- and then was completed through a venous approach with platinum coils, achieving total occlusion of the fistula. The patient recovered favorably, with progressive improvement of ocular symptoms. He experienced mild right XII nerve palsy postoperatively, which was treated with steroids. He was discharged on the fifth day. At 6-month follow-up, the lesion showed no persistence on magnetic resonance images. Conclusion. A case of arteriovenous dural fistula of the hypoglossal canal treated endovascularly with complete occlusion is presented

The femoral artery is the most used percutaneous access site for different endovascular therapeutic options, this being an excellent anatomical site to achieve adequate compression after its puncture, which frequently makes it the site with the highest incidence of complications associated with posterior to arterial puncture. The most frequent complications related to arterial puncture are: hematoma, pseudoaneurysm, retroperitoneal hematoma, and arterial occlusion. The pseudoaneurysm is defined as the interruption in the wall of the artery, product of the lesion of the wall, which causes blood leakage towards the surrounding tissues, remaining contained in a fibrin sac, therefore, the importance of an adequate diagnosis and treatment lies above all in the high risk of rupture or thromboembolism.
ABSTRACT
RESUMEN Antecedentes : los aneurismas de arterias viscerales (AAV) tienen una frecuencia baja (0,1 a 2%). Hasta un 25% puede presentarse como rotura, con una alta mortalidad (hasta 70%). La terapia endovascular ha ganado terreno y se recomienda como primera opción según las últimas guías. Hoy en día, es posible adaptarse a casi cualquier anatomía utilizando tecnología cerebral. Objetivo : describir la experiencia y enfoque en el manejo endovascular de AAV, con resultados a corto, mediano y largo plazo. Material y métodos : llevamos a cabo una evaluación retrospectiva de pacientes tratados por AAV verdaderos por vía endovascular en un solo centro entre 2010 y 2020, con un seguimiento mínimo de 6 meses. Resultados : analizamos 19 procedimientos en 18 pacientes (9 hombres y 9 mujeres). La edad promedio fue 61,9 años; el promedio de tiempo de internación fue 1,94 días y el promedio de seguimiento de 40 meses. La arteria más involucrada fue la esplénica (n = 9, 50%). El tamaño aneurismático promedio fue 30,1 mm. La estrategia terapéutica más utilizada fue colocación de diversor de flujo (n = 8, 42,1%). Dos pacientes fueron reintervenidos (11,1%). Las tasas de exclusión completa fueron del 47,4%, 68,4% y 94,7% a los 3, 6 y 12 meses, respectivamente. No hubo casos de mortalidad a 30 días ni mortalidad relacionada con el aneurisma durante el seguimiento. Conclusión : el tratamiento endovascular de los AAV es seguro y eficaz. Sin embargo, se debe contar con la tecnología adecuada, para la planificación preoperatoria y el tratamiento.
ABSTRACT Background : the prevalence of visceral artery aneurysms (VAAs) is low (0.1 to 2%). Up to 25% may present as rupture which is associated with high mortality (up to 70%). Endovascular treatment has gained ground and is even considered the first option according to the most recent recommendations. Nowadays, almost any anatomy can be approached with endovascular techniques used to treat intracranial aneurysms. Objective : the aim of our study was to describe the experience and approach for the endovascular management of VAAs with short-, mid-, and long-term results. Material and methods : we conducted a retrospective evaluation of patients with true VAAs undergoing endovascular treatment in a single center between 2010 and 2020 who were followed up for a minimum of 6 months. Results : we analyzed 19 procedures in 18 patients (9 men and 9 women). Mean age was 61.9 years; mean length of hospital stay was 1.94 days and mean follow-up was 40 months. The splenic artery was the vessel most affected (n = 9, 50%). Mean aneurysm size was 30.1 mm. Flow diversion was the strategy most used (n = 8, 42.1%). Two patients required reintervention (11%). Complete exclusion rate was 38.4%, 47.4%, 68.4% and 94.7% at 3, 6 and 12 months, respectively. There were no cases of mortality within the first 30 days and no aneurysm-related mortality during the follow-up period. Conclusion : endovascular treatment of VAAs is a safe and efficient strategy but requires adequate technology for preoperative planning and treatment.
ABSTRACT
This study aimed to investigate the relationship between prescription drugs and the slow-flow phenomenon after drug-coated balloon angioplasty. Of 30 patients, five (17%) presented with the slow-flow phenomenon. Patients with the slow-flow phenomenon were significantly less commonly prescribed calcium channel blockers than those without the slow-flow phenomenon (P ¼ 0.03). There was no intergroup difference in the prescription of angiotensin II receptor blockers and b-blockers. The clinical outcomes, including restenosis, thrombosis, target lesion revascularization, and death, did not differ between groups during the 10-month observation period.
ABSTRACT
Abstract Objectives: This study explored the association between insomnia and the clinical outcome of large vessel occlusion Acute Ischemic Stroke (AIS) and attempted to explore its potential mechanisms from the perspectives of inflammation and oxidative stress. Methods: AIS patients who underwent endovascular treatment for large vessel occlusion at Binzhou Central Hospital from 2018 to 2022 (n = 508) were included. Patients were divided into an insomnia group and a non-insomnia group. Insomnia was judged by self-reported Athens Insomnia Scale score. Regression analysis was used to compare the differences in the 24-hour and 7-day National Institutes of Health Stroke Scale (NIHSS) score, Early Neurological Deterioration (END), early adverse event incidence, 90-day prognosis and mortality, and serum bio-markers levels. Results: The incidence of insomnia in the study population was 39.6% (n = 144, insomnia group; n = 364, non-insomnia group). Compared with the non-insomnia group, a worse prognosis outcome (63% vs. 49%, adjusted rate ratio: 1.8, 95% Confidence Interval: 1.2-3.7; p = 0.016), higher 24-h and 7-day NIHSS score (17 [9-36] vs. 13 [5-20]; p = 0.024, and 11 [4‒24) vs. 8 [2‒14]; p = 0.031, respectively), higher END (24% vs. 15%, p = 0.022), and higher incidence of adverse events were observed in the insomnia group (79% vs. 59%, p = 0.010). The 90-day mortality was higher in the insomnia group than that in the non-insomnia group (22% vs. 17%), however, such a difference was not statistically significant. Conclusion: Insomnia is closely related to the clinical outcome of AIS with large vessel occlusion, and inflammation and oxidative stress mechanisms may be involved.
ABSTRACT
Objective:To investigate the association between door-in-door-out time (DIDO) and clinical outcome of patients with acute large vessel occlusion stroke (AIS-LVO) of anterior circulation after early endovascular therapy (EVT).Methods:The patients with AIS-LVO of anterior circulation who received EVT in the advanced stroke center of the Yijishan Hospital of Wannan Medical College from February 2019 to December 2021 were retrospectively analyzed. The baseline characteristics, time metrics and clinical outcomes were collected. DIDO was defined as the duration of time from arrival to referral at the primary stroke center, and the primary outcome was favorable clinical outcome, as evaluated by a modified Rankin Scale score of 0 to 2 at 3 months after EVT. Univariate and multivariate regression analysis was used to explore the relationship between DIDO and early endovascular treatment clinical outcomes in patients with AIS-LVO.Results:A total of 320 patients [aged (69.6±10.2) years] were enrolled. The baseline National Institutes of Health Stroke Scale score and Alberta Stroke Program early CT score were 14 (11, 18) and 8 (7, 9). The DIDO time was 76 (50, 120) minutes. DIDO was not an independent correlation factor for clinical outcomes in patients with EVT in the overall population. However, in patients receiving early EVT (onset-to-reperfusion≤300 minutes), DIDO ( OR=1.030, 95% CI 1.001-1.059, P=0.041) was an independent correlating factor of clinical outcome in patients with EVT. According to the receiver operating characteristic curve, the DIDO cutoff of 74.5 minutes can be used as an important indicator of prehospital delay in referral to EVT for large vascular occlusion stroke. Door to computed tomography time ( OR=1.393, 95% CI 1.212-1.601, P<0.001) and computed tomography to transfer time ( OR=1.386, 95% CI 1.220-1.575, P<0.001) were factors associated with DIDO≤74.5 minutes in a multivariate analysis in this time frame. Conclusions:In transferred patients undergoing EVT early, DIDO has a signifificant impact on clinical outcome. DIDO can be used as an important quality control indicator to evaluate the referral process for patients with AIS-LVO.
ABSTRACT
@#Objective To investigate the effect of in vitro fenestration on reconstruction of left subclavian artery in endovascular treatment of aortic dissection. Methods A total of 89 patients with aortic dissection involving left subclavian artery were treated by endovascular treatment in the Second Affiliated Hospital of Fujian Medical University from February 2017 to January 2020. There were 44 patients in the test group, including 36 males and 8 females, with an average age of 58.02±13.58 years. There were 45 patients in the control group, including 35 males and 10 females, with an average age of 54.10±12.32 years. The left subclavian artery was reconstructed by in vitro fenestration in the test group and by chimney technique in the control group. The clinical data were compared between the two groups. Results The operation time of the test group was longer than that of the control group (126.16±7.53 min vs. 96.49±6.52 min, P<0.01). The median follow-up time was 31 (13-48) months. The incidence of endoleak in the test group (4.7%) was lower than that in the control group (18.6%, P=0.04) during the follow-up. There was no statistical difference in the incidence of stroke, myocardial infarction, false lumen thrombosis, retrograde aortic dissection or left subclavian artery occlusion between the two groups (P>0.05). Conclusion In vitro fenestration for reconstructing left subclavian artery in thoracic endovascular aortic repair of aortic dissection is safe and feasible, which is worthy of further clinical promotion.
ABSTRACT
Lower extremity atherosclerotic occlusive disease is a common vascular disease, mainly peripheral arterial disease caused by atherosclerotic plaque formation of lower extremity arterial stenosis, occlusion, resulting in chronic ischemia of the limbs. In recent years, endovascular therapy has made remarkable progress and has become the treatment of choice for atherosclerotic occlusive disease of the lower extremities. With the continuous improvement of surgical methods, the success rate of endovascular treatment has increased dramatically, but there are some differences between different interventional modalities, and the adaptive population may be different, this paper provides a review of the current progress of endovascular treatment and combines the relevant literature at domestic and international.

Objective To explore the safety and efficacy of endovascular treatment(EVT)in patients with acute posterior circulation ischemic stroke over 24 hours from onset.Methods This retrospective study retrospectively analyzed patients with acute posterior circulation ischemic stroke who received EVT in the Department of Neurology,First Hospital of Jilin University from June 2018 to June 2023.The patient's gender,age and other related demographic information were collected.The related examination results of patients were collected,including admission rapid blood glucose,admission systolic blood pressure,admission diastolic blood pressure.The related risk factors of stroke of patients were collected,including previous transient ischemic attack,hypertension,diabetes,atrial fibrillation,and history of drinking,smoking history,etc.;other related indicators were collected,including intravenous thrombolysis,tandem lesions,awakening stroke,baseline National Institutes of Health stroke scale(NIHSS)score,and baseline posterior circulation Alberta stroke program early CT score(pc-ASPECTS),collateral circulation grade of American Society of Interventional and Therapeutic Neuroradiology/Society of Interventional Radiology(ASITN/SIR),onset to EVT puncture time,the trial of org 10172 in acute stroke treatment(TOAST)classification and outcome indicators(efficacy indicators included 90 days Modified Rankin scale[mRS]score≤3 after EVT,successful recanalization[extended cerebral infarction thrombolytic recanalization class 2b-3];security indexes included symptomatic intracranial hemorrhage[sICH]within 24 h after EVT and 90 d mortality after EVT).According to the symptom onset to EVT puncture time,the patients were divided into two groups:≤24h group and>24h group.The patients with onset time>24 h and those with onset time≤24 h were matched at a ratio of 1:1 by propensity score matching(PSM).All patients were divided into poor prognosis group(mRS score>3)and good prognosis group(mRS score ≤ 3)according to mRS score at 90 days after EVT.Using univariate and multivariate Logistic regression was used to analyze the effect of onset time on clinical outcomes at 90 days after EVT.Results A total of 366 patients were enrolled in this study,including 284 males and 82 females.The median age was 61(55,68)years old,ranging from 25 to 91 years old.Before PSM,the>24h group had lower prevalence of atrial fibrillation(2.02%[2/99]vs.9.74%[26/267],P=0.025)and lower baseline NIHSS score(10.0[5.0,19.0]vs.14.0[10.0,35.0],P<0.01)and higher ASTIN/SIR collateral grade(P=0.018).After PSM,we did not find statistical difference between the two groups in baseline characteristics except for the onset to EVT puncture time.Before and after PSM,there was no significant difference in efficacy and safety between the onset time>24 h group and the onset time ≤24h group.Univariate binary Logistic regression analysis showed that hypertension(OR,0.613,95%CI 0.391-0.942,P=0.025),intravenous thrombolysis(OR,3.235,95%CI 1.316-9.237,P=0.010),baseline NIHSS score(OR,0.975,95%CI 0.957-0.988,P<0.01),baseline pc-ASPECTS(OR,1.281,95%CI 1.101-1.482,P=0.001)and sICH within 24 h after EVT(OR,0.070,95%CI 0.000-0.330,P<0.01)were significantly correlated with prognosis.Gender,age,hypertension,baseline NIHSS score,intravenous thrombolysis,baseline pc-ASPECTS,ASTIN/SIR collateral grade,onset time>24 h and sICH within 24 h after EVT were included in the multivariate binary Logistic regression analysis.The multivariate binary Logistic regression analysis showed that the onset time>24 h was not associated with poor prognosis 90 d after EVT(aOR,1.635,95%CI 0.936-2.893,P=0.087).Conclusion EVT for acute posterior circulation ischemic stroke more than 24 hours after onset is feasible under strict imaging screening,and its safety and efficacy are similar to those in patients with onset under 24 hours.
ABSTRACT
@#Objective To investigate the relationship between NLR and symptomatic intracranial hemorrhage (sICH) in patients with acute anterior circulation stroke undergoing endovascular treatment. Methods A total of 437 consecutive patients with acute stroke treated with endovascular treatment (EVT) were included. The patients were divided into two groups according to whether symptomatic intracranial hemorrhage was present. Univariate and multivariate analyses were performed. Results Compared with the non-symptomatic intracranial hemorrhage group. Multivariate Logistic regression analysis showed that the history of stroke and neutrophil/lymphocyte ratio were independent risk factors for postoperative symptomatic intracranial hemorrhage. The Area Under The Curve(AUC) value of NLR showed moderate accuracy,with an AUC value of 0.589 (95%CI 0.509-0.688,P=0.029). The NSE cut-off value was set at 5.89.When the NLR≥ 5.89,the sensitivity was 65.00%,and the specificity was 51.65% (P=0.029). Conclusion Elevated NLR is an independent predictor for patients with acute anterior circulation stroke who are undergoing endovascular treatment.
ABSTRACT
Objective:To analyze the safety and efficacy of endovascular treatment in fusiform aneurysms at V4 segment of vertebral artery.Methods:Twenty-five patients with fusiform aneurysms at V4 segment of vertebral artery, accepted endovascular treatment in Department of Cerebrovascular Diseases, Second Affiliated Hospital of Kunming Medical University from May 2016 to January 2022 were chosen; their clinical data were retrospectively analyzed. The short-term (within one month of surgery) and long-term (>8 months of surgery) complications were evaluated, including aneurysm re-bleeding and ischemic stroke. All patients were followed up for 3-21 months; aneurysm recurrence and parent arteries were evaluated by DSA. The prognosis of patients was evaluated by modified Rankin scale (mRS) at the last follow-up (mRS scores of 0-2 as good prognosis).Results:Twenty-six aneurysms involved in 25 patients, including 13 ruptured aneurysms and 13 un-ruptured aneurysms; 7 aneurysms were located at the dominant vertebral artery and 7 aneurysms involved in the origin of posterior inferior cerebellar artery (PICA). In these 13 ruptured aneurysms, 6 (46.15%) were treated with parent artery sacrifice and 7 (53.85%) were with stent-assisted coil embolization; in 13 un-ruptured aneurysms, 9 (69.23%) were treated with stent-assisted coil embolization and 4 (30.77%) were with flow diversion devices (Tubridge). Seven aneurysms (43.75%) used multi-stent in these 16 aneurysms accepted stent-assisted coil embolization. No short-term and long-term re-bleeding or ischemic stroke were noted in all patients. Twenty patients completed DSA follow-up, with a median follow-up time of 8 months; 3 patients had recurrent aneurysms and one had asymptomatic stent occlusion. All 25 patients completed the last follow-up (telephone or outpatient follow-up) in May 2022, and 24 had good prognosis.Conclusion:According to characteristics of dominant vertebral artery and relations between aneurysms and PICA, individualized endovascular treatment can be safe and effective in fusiform aneurysms at V4 segment of vertebral artery.
ABSTRACT
Objective:To investigate the therapeutic value of interventional embolization on feeding artery in intracranial hypervascular tumors.Methods:Forty-five patients with intracranial hypervascular tumors, admitted to and accepted interventional embolization of the feeding artery before craniotomy in Department of Neurosurgery, Huashan Hospital Affiliated to Fudan University from March 2019 to August 2022, were chosen; a retrospective analysis was performed on the clinical data of these patients. The imaging characteristics, pathological types, preoperative embolization indications, embolization effects and embolism-related complications were summarized to evaluate the safety and effecacy of preoperative interventional embolization.Results:Among the 45 patients, 21 patients had hemangioblastomas, 15 had meningiomas, 5 had hemangiopericytomas, and 4 had glomus jugular tumors. The technical success rate of interventional embolization was 97.8% (44/45); in this frustrated case, the middle meningeal artery was too circuitous for microcatheter to pass. Among the successful ones, 41 patients used liquid embolism agent onyx and 3 patients applied liquid embolism agent NBCA. Seven, 26 and the rest 11 patients achieved complete embolization, sub-total embolization and partial embolization, respectively. Four patients had embolism-related complications, including 2 with rupture of middle meningeal arteries, 1 with Marathon catheter failed to be pulled out, and 1 with functional glomus jugular tumor having pheochromocytoma crisis; these 4 patients were treated timely without serious complications.Conclusion:For intracranial hypervascular tumors, preoperative interventional embolization is safe and effective; it is necessary to master embolization indications and select appropriate embolization methods and materials.
ABSTRACT
Objective:To investigate the safety of tirofiban in patients with anterior circulation acute large vessel occlusion cerebral infarction during bridging endovascular treatment (EVT) after intravenous thrombolysis (IVT).Methods:Two hundred and three patients received bridging EVT after IVT in Department of Intervention, First Affiliated Hospital of Soochow University from January 2017 to January 2022 were chosen. Patients were divided into tirofiban group ( n=80) and non-tirofiban group ( n=123) according to whether or not tirofiban was used during EVT, and then patients from tirofiban group were subdivided into stent implantation group ( n=52) and non-stent implantation group ( n=28) according to whether or not emergency stent implantation was performed. The clinical data, safety indexes (intracranial hemorrhage [ICH] rate 24 h, 2-3 d, and 90 d after EVT, new ICH incidence 3-90 d after EVT, fatal ICH rate, and mortality 90 d after EVT), and prognoses 90 d after EVT were compared. Results:(1) Compared with the non-tirofiban group, the tirofiban group had significantly higher proportions of males, and patients with tandem occlusion, balloon dilation or stent implantation, and statistically lower proportion of patients with atrial fibrillation, significantly longer surgical time, and significantly different distribution of stroke types ( P<0.05). No significant differences were noted in ICH incidences 24 h after EVT, 2-3 d after EVT and 90 d after EVT, fatal ICH incidence, mortality incidence 90 d after EVT, or good prognosis rate 90 d after surgery between tirofiban group and non-tirofiban group ( P>0.05). (2) Patients in the stent implantation group had significantly higher percentages of tandem occlusion and balloon dilation compared with those in the non-stent implantation group ( P<0.05). No significant difference was noted in good prognosis rate 90 d after EVT or new ICH incidence 3-90 d after EVT between the stent implantation group and the non-stent implantation group ( P>0.05). Compared with the non-stent implantation group, the stent implantation group had statistically higher ICH incidences 24 h after EVT, 2-3 d after EVT, and 90 d after EVT, significantly higher fatal ICH incidence and mortality 90 d after EVT ( P<0.05). Conclusion:Tirofiban is safe in patients with anterior circulation acute large vessel occlusion cerebral infarction during EVT after IVT; however, if emergency stent implantation is performed, it will lead to increased intracranial hemorrhage and mortality.
