Microsurgical management of a ruptured intracranial mycotic aneurysm in infancy.

INTRODUCTION: During infancy, infectious aneurysms are uncommon and potentially fatal lesions with an imminent risk of intracranial hemorrhage development. CASE PRESENTATION: A 1-month-old infant presented with loss of consciousness and clonic movements of the right superior limb after a work-up for Hirschsprung's disease. His physical exam revealed stupor, miosis, anterior fontanelle swelling, and hyperreflexia of the right superior limb. Blood cultures were positive for Candida albicans. In addition, brain imaging revealed an intraparenchymal hematoma in the left temporal lobe and a saccular aneurysm at the M3 segment of the left middle cerebral artery. Upon careful discussion with the patient's family, he underwent evacuation of the hematoma and aneurysm repair. His postoperative clinical course was uneventful. At the 5-month follow-up, a brain MRI showed encephalomalacia in the area of prior hemorrhage. Furthermore, he had preserved motor function and adequate psychomotor development on subsequent pediatric evaluations. CONCLUSION: Microsurgical management of ruptured mycotic aneurysms demands a systematic work-up and nuanced appraisal of clinical and aneurysmal factors. Operating in a confined space and considering the fragile nature of aneurysms are of utmost relevance for effectively treating these lesions.

Andexanet Alfa versus Four-Factor Prothrombin Complex Concentrate for the Reversal of Factor Xa (FXa) Inhibitor-Associated Intracranial Hemorrhage: A Systematic Review of Retrospective Studies.

Background/Objectives: There are limited data on the risks and benefits of using Andexanet alfa (AA) compared with four-factor prothrombin complex concentrate (4F-PCC) for the reversal of factor Xa inhibitor-associated intracranial hemorrhage (ICH). Our aim was to describe a compilation of the information available in the literature to date. Methods: PubMed, Embase, Web of Science (Clarivate Analytics) and the Cochrane Central Register of Controlled Trials were searched until December 2023. Following the "Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)" guidelines, our systematic literature review included studies that were retrospective in design and evaluated both drugs to control bleeding and complications (death and thromboembolic events). Two researchers re-examined the studies for relevance, extracted the data and assessed the risk of bias. No meta-analyses were performed for the results. Results: In this limited patient sample, we found no differences between published articles in terms of neuroimaging stability or thrombotic events. However, some studies show significant differences in mortality, suggesting that one of the AAs may be superior to 4F-PCC. Conclusions: Our qualitative analysis shows that AA has a better efficacy profile compared with 4F-PCC. However, further studies monitoring these patients and a multicenter collaborative network dedicated to this topic are needed.

Giant cerebral cavernous malformation in a newborn: a rare case report and review of literature.

BACKGROUND: Cavernous malformations (CMs), also known as cavernomas or cavernous angiomas, are vascular malformations characterized by sinusoidal spaces lined by endothelial cells. Giant CMs (GCMs) are extremely rare, with limited understanding of their presentation and management. We present a case of symptomatic GCM in a newborn and review the literature on this rare entity. CASE DESCRIPTION: A 1-month-old newborn presented with focal seizures and signs of increased intracranial pressure. Imaging revealed a massive right frontal-parietal GCM, prompting surgical resection. Histopathological examination confirmed the diagnosis of cerebral cavernous malformation. The patient recovered well postoperatively with no neurological deficits. CONCLUSIONS: GCMs are exceedingly rare in children and have not been reported in newborns until now. Symptoms typically include seizures and mass effects. Gross total resection is the standard treatment, offering favorable outcomes. Further research is needed to understand the natural history and optimal management of GCMs, particularly in newborns, emphasizing the importance of heightened clinical awareness for timely diagnosis and appropriate management.

Infratentorial Cerebral Cavernous Malformation May be a Risk Factor for Symptomatic Bleeding and Precocity of Symptoms: A Multicenter, Propensity Score Matched, Case-Control Study.

BACKGROUND: Cerebral Cavernous Malformation (CCM) is one of the most common types of vascular malformation of the central nervous system. Intracerebral hemorrhage, seizures, and lesional growth are the main clinical manifestations. Natural history studies have tried to identify many risk factors; however, the clinical course remains highly unpredictable. OBJECTIVE: Here, we have analyzed a multicenter CCM cohort looking for the differential clinical data regarding the patients harboring supra and/or infratentorial cavernous malformations in order to better understand risk factors involved in the anatomical location of the unique neurosurgical disease. METHODS: We have presented a multicenter, Propensity Score Matched (PSM), case-control study including 149 consecutive CCM cases clinically evaluated from May 2017 to December 2022 from three different neurosurgical centers. Epidemiological data were defined at each clinical assessment. Logistic regression was used to identify the independent contribution of each possible risk factor to the bleeding risk. To balance baseline covariates between patients with and without symptoms, and specifically between those with and without symptomatic bleeding, we used a PSM strategy. The Kaplan-Meier curve was drawn to evaluate if patients with infratentorial lesions had a greater chance of bleeding earlier in their life. RESULTS: The presence of infratentorial lesions was a risk factor in the multivariate analysis comparing the bleeding risk with pure asymptomatic individuals (OR: 3.23, 95% CI 1.43 - 7.26, P = 0.005). Also, having an infratentorial CCM was a risk factor after PSM (OR: 4.56, 95% CI 1.47 - 14.10, P = 0.008). The presence of an infratentorial lesion was related to precocity of symptoms when the time to first bleed was compared to all other clinical presentations in the overall cohort (P = 0.0328) and in the PSM group (P = 0.03). CONCLUSION: Here, we have provided some evidence that infratentorial cerebral cavernous malformation may have a more aggressive clinical course, being a risk factor for symptomatic haemorrhage and precocity of bleeding.

Is near-infrared spectroscopy a promising predictor for early intracranial hemorrhage diagnosis in the Emergency Department?

Intracranial hemorrhage (ICH) is a serious medical condition that can lead to significant morbidity and mortality if not diagnosed and treated promptly. Early detection and treatment are essential for improving the outcome in patients with ICH. Near-infrared spectroscopy (NIRS) is a non-invasive imaging technique that has been used to detect changes in brain tissue oxygenation and blood flow in various conditions. The aim of this study was to investigate the predictive potential of NIRS for early diagnosis of ICH in patients presenting to the Emergency Department (ED) triage with headache. A total of 378 patients were included in the study. According to the final diagnosis of the patients, 4 groups were formed: migraine, tension-cluster headache, intracranial hemorrhage and intracranial mass, and control group. Cerebral NIRS values "rSO2" were measured at the first professional medical contact with the patient. The right and left rSO2 (RrSO2, LrSO2) were significantly lower and the rSO2 difference was significantly higher in the intracranial hemorrhage group compared to all other patient groups (P<0.001). The cut-off values determined in the receiver operating characteristics (ROC) analysis were RrSO2 ≤67, LrSO2 ≤67, and ΔrSO2 ≥9. This study found that a difference of more than 9 in cerebral right-left NIRS values can be a non-invasive, easy-to-administer, rapid, and reliable diagnostic test for early detection of intracranial bleeding. NIRS holds promise as an objective method in ED triage for patients with intracranial hemorrhage. However, further research is needed to fully understand the potential benefits and limitations of this method.

[Systolic blood pressure reduction in patients with intracranial hemorrhage and functional prognosis]. / Reducción de la presión arterial sistólica en pacientes con hemorragia intracraneal y pronóstico funcional.

Background: Acute intracerebral hemorrhage affects annually more than 1 million people worldwide. Chronic systemic arterial hypertension is the most important modifiable risk factor for spontaneous intracerebral hemorrhage. Objective: To determine the relationship between the decrease in systolic blood pressure (SBP) in patients with intracranial hemorrhage and their short-term functional prognosis. Material and methods: Observational, longitudinal, prospective study in patients with intraparenchymal hemorrhage secondary to hypertensive dyscontrol, older than 18 years, of both sexes. Blood pressure was recorded at admission, every hour during the first 6 hours and every two hours from 8 to 24 hours after admission. Functionality was assessed using the modified Rankin scale at admission, at 6 and 24 hours after admission. Results: 58 patients were included, in whom the reduction of systolic blood pressure at admission was 17.04% and at 24 hours was 31.3 mm Hg; the mean systolic blood pressure was 183.62 mm Hg as opposed to 152.3 mm Hg at discharge (p < 0.001). Conclusions: In the first 6 hours, reduction in ASR is significantly associated with hospital outcome in patients with intracranial hemorrhage. A linear association was observed with improvement and favorable functional prognosis as measured by the modified Rankin scale.

Introducción: la hemorragia intracerebral aguda afecta anualmente a más de un millón de personas en todo el mundo. La hipertensión arterial sistémica crónica es el factor de riesgo modificable más importante para la hemorragia intracerebral espontánea. Objetivo: determinar la relación entre la disminución de la presión arterial sistólica (TAS) en pacientes con hemorragia intracraneal y su pronóstico funcional a corto plazo. Métodos: estudio observacional, longitudinal, prospectivo, en pacientes con hemorragia intraparenquimatosa secundaria a descontrol hipertensivo, mayores de 18 años, de ambos sexos. Se realizaron registros de presión arterial al ingreso, cada hora durante las primeras seis horas y cada dos horas desde las ocho a las 24 horas posterior al ingreso. Se evaluó funcionalidad mediante escala de Rankin modificada al ingreso, a las seis y a las 24 horas después del ingreso. Resultados: se incluyeron 58 pacientes, en quienes la reducción de la TAS al ingreso fue de 17.04% y a las 24 horas fue de 31.3 mm Hg de la presión arterial sistólica; la media de la TAS fue de 183.62 mm Hg a diferencia de la registrada al egreso, que fue de 152.3 mm Hg (p < 0.001). Conclusiones: en las primeras seis horas, la reducción de la TAS está significativamente asociada con el resultado hospitalario en pacientes con hemorragia intracraneal. Se observó una asociación lineal con la mejoría y un pronóstico funcional favorable, medido por la escala de Rankin modificada.

Complicaciones neurológicas de la prematuridad / Neurological consequences of prematurity

Resumen Los nacimientos prematuros representan un in dicador importante de salud de un país. Estos niños tienen un mayor riesgo de mortalidad y morbilidad. Las principales lesiones encefálicas en los prematuros incluyen lesiones de la sustancia blanca, hemorragias intracraneanas y lesiones cerebelosas, que pueden ser detectadas mediante ecografía encefálica y resonancia magnética, siendo esta última la técnica más sensible. Estas lesiones pueden tener repercusión a largo plazo en el neurodesarrollo de los prematuros, con un mayor riesgo de parálisis cerebral, trastornos cognitivos, con ductuales, sensoriales y del aprendizaje, entre otros. Es fundamental aplicar estrategias de prevención y aten ción temprana para reducir las consecuencias negativas de las lesiones encefálicas asociadas a la prematuridad.

Abstract Premature births are an important health indicator for a country. These children have a higher risk of mor tality and morbidity. The main brain injuries in preterm infants include white matter injuries, intracranial hem orrhages, and cerebellar injuries. These injuries can be detected through brain ultrasound and magnetic reso nance imaging (MRI), with MRI being the most sensitive technique. Perinatal brain injuries may have long-term consequences on the neurodevelopment of preterm infants, with an increased risk of cerebral palsy, cogni tive, behavioral, sensory, and learning disorders, among others. It is key to implement prevention strategies and early intervention to reduce the negative consequences of brain injuries associated with prematurity.

Deficiencia congénita de factor VII / Congenital factor VII deficiency

Resumen La deficiencia congénita de factor VII es uno de los desórdenes congénitos de la coagulación más comunes, con una prevalencia a nivel mundial de 1:300,000- 1:500,000. Se presenta el caso de un paciente masculino de 37 semanas y 5 días, nacido por cesárea intraparto y con el antecedente heredofamiliar de muerte de hermano a los 4 días de nacido por hemorragia intracraneal, quien a los 14 días de nacido es llevado a emergencias por sangrado umbilical que persistía después del desprendimiento del cordón. Su abordaje inicial incluyó la toma de tiempos de coagulación, lo que mostró alteración del tiempo de protrombina con tiempo de tromboplastina parcial y fibrinógeno normales. El sangrado, así como el tiempo de protrombina prolongado, persistió a pesar de que se administrara vitamina K en tres ocasiones y de transfundir plasma fresco congelado. Se sospechó defecto congénito de factor VII, que se confirmó con la cuantificación del factor. A los 2 meses y 10 días de edad, se le realizaron estudios moleculares basados en secuenciación masiva de nueva generación (NGS por sus siglas en inglés). El análisis determinó dos variantes heterocigotas: F7, intrón 5, c.430+1G>A y F7, intrón 8, c.805+1G>A. Actualmente, el paciente se maneja con profilaxis 5 días de la semana con factor VII recombinante 200 µg/día intravenoso (280 µg/kg) sin recurrencia de sangrados.

Abstract Factor VII congenital deficiency is one of the most common congenital deficiencies of the blood system, with a worldwide prevalence of 1:300,000- 1:500,000. Here we describe a male patient, born by C section, with the family history of death at 4 days old of a sibling caused by intracranial hemorrhage, who presented bleeding at the umbilical cord site at 14 days old, even after falling of the cord. The initial assessment included laboratory tests with coagulation times revealing prolonged prothrombin time, with normal partial thromboplastin time as well as fibrinogen. The bleeding and the prolonged prothrombin time persisted despite the administration of vitamin K in three doses as well as fresh frozen plasma. Congenital defect of factor VII was suspected and later confirmed by measuring the factor. At the age of 2 months and 10 days, molecular studies based on next-generation massive sequencing (NGS) were performed. The analysis exhibited two heterozygous variants: F7, intron 5, c.430+1G>A y F7, intron 8, c.805+1G>A. Currently the patient is receiving prophylaxis 5 days per week with recombinant factor VII 200 µg/ day intravenous (280 µg/kg) with no recurrent bleeding.

ST­segment elevation associated with intraparenchymal hemorrhage: A case report.

The electrocardiogram (ECG) changes in patients with intraparenchymal hemorrhage (IPH) have remained largely elusive and no case reports are currently available in the scientific literature. The medical management of a patient with ST-segment elevation associated with IPH was described in the present study. The case report describes a 78-year-old male patient who presented with ST-segment elevation in V1, V2, V3 and V4 on ECG. Initially, the case was managed therapeutically as an acute myocardial infarction. Later, the patient was transferred to a higher-level hospital, where a new ECG confirmed ST-segment elevation. Simple skull tomography was also performed, which revealed a spontaneous right basal ganglion in the context of an acute cerebrovascular accident of hypertensive origin. A transthoracic ECG was ordered, which revealed an ejection fraction of 65% with type I diastolic dysfunction due to relaxation disorders and without any signs of ischemia, intracavitary masses or thrombi. In addition to the presence of nonspecific ECG findings, clinicians should consider immediate brain computed tomography to confirm intracranial hemorrhage.

Children Newly Diagnosed with Fetal and Neonatal Alloimmune Thrombocytopenia: Neurodevelopmental Outcome at School Age.

OBJECTIVE: To evaluate the neurodevelopmental outcome at school age in children newly diagnosed with fetal and neonatal alloimmune thrombocytopenia (FNAIT). STUDY DESIGN: This observational cohort study included children diagnosed with FNAIT between 2002 and 2014. Children were invited for cognitive and neurological testing. Behavioral questionnaires and school performance results were obtained. A composite outcome of neurodevelopmental impairment (NDI) was used, defined, and subdivided into mild-to-moderate and severe NDI. Primary outcome was severe NDI, defined as IQ <70, cerebral palsy with Gross Motor Functioning Classification System level ≥ III, or severe visual/hearing impairment. Mild-to-moderate NDI was defined as IQ 70-85, minor neurological dysfunction or cerebral palsy with Gross Motor Functioning Classification System level ≤ II, or mild visual/hearing impairment. RESULTS: In total, 44 children were included at a median age of 12 years (range: 6-17 years). Neuroimaging at diagnosis was available in 82% (36/44) of children. High-grade intracranial hemorrhage (ICH) was detected in 14% (5/36). Severe NDI was detected in 7% (3/44); two children had high-grade ICH, and one had low-grade ICH and perinatal asphyxia. Mild-to-moderate NDI was detected in 25% (11/44); one child had high-grade ICH, and eight children were without ICH, yet for two children, neuroimaging was not performed. Adverse outcome (perinatal death or NDI) was 39% (19/49). Four children (9%) attended special needs education, three of whom had severe NDI and one had mild-to-moderate NDI. Total behavioral problems within the clinical range were reported in 12%, which is comparable with 10% in the general Dutch population. CONCLUSION: Children who are newly diagnosed with FNAIT are at increased risk for long-term neurodevelopmental problems, even those without ICH. TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov (Identifier: NCT04529382).

Saccular intracranial neonatal aneurysm.

INTRODUCTION: Neonatal cerebral aneurysms are very rare condition and distinct from those of the adults. CASE REPORT: We reported a 14-day-old male neonate who presented subarachnoid hemorrhage due to a ruptured anterior cerebral artery saccular aneurysm. In addition, we present a review of the relevant literature. CONCLUSION: Intracranial hemorrhage due to cerebral aneurysm rupture in a newborn is an uncommon diagnosis, but it must be unequivocally excluded.

Introduction: Strokes are a health problem and systemic thrombolysis constitutes a reperfusion strategy backed up by significant evidence on its positive therapeutic impact. National reports on its use are scarce. Objectives: To report and analyze results obtained with this therapeutic approach at the Clinicas Hospital. To establish predictive factors for a good evolution, intracranial hemorrhage and mortality. Method: Observational, analytical study of thrombolysed patients at Clinicas Hospital (2010-2021). Results: Systemic thrombolysis was performed in 268 patients. Average NIHSS score was 12 points when admitted to hospital.42 % of cases were total anterior circulation infarct (TACI). Cardioembolic ischaemmic stroke was the most frequent etiopahogenesis. 59.3% of patients were discharged with functional independence and 55.2% had minimal neurologic deficit. Symptomatic intracranial hemorrhage and mortality rates were 7.1% and 18.7% respectively. 57% of patients were assisted within ≤60 minutes they showed up at the ER. Thrombolysis percentage in total number of strokes was 18.9%. Age, NIHSS score upon arrival to hospital and admission to the stroke unit were significant variables to predict a good evolution, intracranial hemorrhage and death. Discussion and conclusions: The large number of cases in the country was reported. Effectiveness and safety parameters for this treatment were comparable to those reported internationally. The good door-to-needle time and thrombolysis rate versus total number of strokes stood out as satisfactory indicators of healthcare quality. Admission to the stroke unit behaved as a predictive factor of functional independence and it protected patients from hospital mortality.

The reverse question mark and L.G. Kempe incisions for decompressive craniectomy: A case series and narrative review of the literature.

Background: Decompressive craniectomy (DC) is a lifesaving procedure, relieving intracranial hypertension. Conventionally, DCs are performed by a reverse question mark (RQM) incision. However, the use of the L. G. Kempe's (LGK) incision has increased in the last decade. We aim to describe the surgical nuances of the LGK and the standard RQM incisions to treat patients with severe traumatic brain injury (TBI), intracranial hemorrhage (ICH), empyema, and malignant ischemic stroke. Furthermore, to describe, surgical limitations, wound healing, and neurological outcomes related to each technique. Methods: To describe a prospective acquired, case series including patients who underwent a DC using either an RQM or an LGK incision in our institution between 2019 and 2020. Results: A total of 27 patients underwent DC. Of those, ten patients were enrolled. The mean age was 42.1 years (26-71), and 60% were male. Five patients underwent DC using a large RQM incision; three had severe TBI, one ICH, and one ischemic stroke. The other five patients underwent DC using an LGK incision (one ICH, one subdural empyema, and one ischemic stroke). About 50% of patients presented severe headaches associated with vomiting, and six presented altered mental status (drowsy or stuporous). Motor deficits were present in four cases. In patients with ischemic or hemorrhagic stroke, symptoms were directly related to the stroke location. Hospital stays varied between 13 and 22 days. No readmissions were recorded, and no fatal outcome was documented during the follow-up. Conclusion: The utility of the LGK incision is comparable with the classic RQM incision to treat acute brain injuries, where an urgent decompression must be performed. Some of these cases include malignant ischemic strokes, ICH, and empyema. No differences were observed between both techniques in terms of prevention of scalp necrosis and general cosmetic outcomes.

Hypertensive primary intraventricular hemorrhage: a systematic review.

Primary intraventricular hemorrhage (PIVH) is a special subtype of intraventricular hemorrhage (IVH) without a hemorrhagic parenchymal component. Different conditions may cause this uncommon hemorrhage including trauma, vascular anomalies, coagulation disorders, and others. Frequently, PIVH is associated with structural vascular anomalies such as aneurysms, arteriovenous malformations, and dural fistulas. Traditionally, hypertension has been considered a predisposing factor for PIVH. A wide variety of studies have been published describing patients with PIVH; however, studies describing exclusively patients with hypertensive PIVH are lacking in the literature. For this reason, the features of PIVH secondary to hypertension are not well described. The purpose of this study is to analyze and describe the characteristics of hypertensive PIVH. A PubMed and Scopus search adhering to Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines was performed to include studies reporting patients with hypertensive PIVH. The search yielded 19 articles reporting retrospective case series. The diagnosis of hypertensive PIVH should be established in patients meeting the following criteria: (a) elevation of blood pressure is observed at admission, (b) a cerebral angiography is negative for vascular anomalies, and (c) other causes of intracranial hemorrhage are ruled out. The prognosis is poorer in patients who present with low Glasgow Coma Score (GCS), old age, hydrocephalus, or more extensive intraventricular bleeding. The results of this study show that hypertension is the most common cause of PIVH, followed by hemorrhage caused by vascular anomalies. Hypertension may be a direct cause of PIVH, but also it may be a predisposing factor for bleeding in cases of an associated vascular anomaly.

Seizure Severity and Treatment Response in Newborn Infants with Seizures Attributed to Intracranial Hemorrhage.

OBJECTIVE: We sought to characterize intracranial hemorrhage (ICH) as a seizure etiology in infants born term and preterm. For infants born term, we sought to compare seizure severity and treatment response for multisite vs single-site ICH and hypoxic-ischemic encephalopathy (HIE) with vs without ICH. STUDY DESIGN: We studied 112 newborn infants with seizures attributed to ICH and 201 infants born at term with seizures attributed to HIE, using a cohort of consecutive infants with clinically diagnosed and/or electrographic seizures prospectively enrolled in the multicenter Neonatal Seizure Registry. We compared seizure severity and treatment response among infants with complicated ICH, defined as multisite vs single-site ICH and HIE with vs without ICH. RESULTS: ICH was a more common seizure etiology in infants born preterm vs term (27% vs 10%, P < .001). Most infants had subclinical seizures (74%) and an incomplete response to initial antiseizure medication (ASM) (68%). In infants born term, multisite ICH was associated with more subclinical seizures than single-site ICH (93% vs 66%, P = .05) and an incomplete response to the initial ASM (100% vs 66%, P = .02). Status epilepticus was more common in HIE with ICH vs HIE alone (38% vs 17%, P = .05). CONCLUSIONS: Seizure severity was greater and treatment response was lower among infants born term with complicated ICH. These data support the use of continuous video electroencephalogram monitoring to accurately detect seizures and a multistep treatment plan that considers early use of multiple ASMs, particularly with parenchymal and high-grade intraventricular hemorrhage and complicated ICH.

Fetal epidural hematoma secondary to a mild blunt prenatal trauma: case report and review of the literature.

Fetal intracranial hemorrhage affects 1 in every 10,000 pregnancies. In most cases, the etiology of the bleeding is multifactorial, and they can be either related to the mother or the fetus. Blunt prenatal trauma was occasionally associated with these hemorrhages, nevertheless, reports of hematomas secondary to mild traumas are rare. Within the prenatal intracranial bleedings, the most frequent are the subarachnoid hematoma and intraparenchymal, scarcely ever the epidural hematoma. Treating these bleedings is challenging due to the ongoing pregnancy. Thus, the prognosis is often reserved, with a mortality rate of 43% and 25% of neurological sequelae. Here, we report a singular case of a fetal epidural hematoma secondary to a mild blunt trauma at the third trimester with a good outcome.

Estratégias de Revascularização em Doentes com Infarto Agudo do Miocárdio em Choque Cardiogênico - Resultados do Registo Português de Síndromes Coronárias Agudas / Revascularization Strategies in Patients with Acute Myocardial Infarction and Cardiogenic Shock: Results from the Portuguese Registry on Acute Coronary Syndromes

Resumo Fundamento: Em doentes com infarto agudo do miocárdio (IAM), choque cardiogênico (CC) e doença multivaso (DMV) persistem dúvidas sobre a intervenção nas artérias não responsáveis. Objetivos: 1) caracterizar a amostra de doentes com IAM, CC e DMV incluídos no Registo Nacional Português de Síndromes Coronárias Agudas (RNSCA); 2) comparar os eventos associados a diferentes estratégias de revascularização; e 3) identificar preditores de mortalidade intra-hospitalar nesta amostra. Métodos: Estudo observacional retrospetivo de doentes com IAM, CC e DMV incluídos no RNSCA entre 2010 e 2018. Compararam-se duas estratégias de revascularização: completa durante o procedimento índice (grupo 1); e completa diferida ou incompleta durante o internamento (grupo 2-3). O endpoint primário foi a ocorrência de reinfarto ou morte intra-hospitalar. A significância estatística foi definida por um valor p < 0,05. Resultados: Identificaram-se 127 doentes com IAM, CC e DMV (18,1% no grupo 1 e 81,9% no grupo 2-3), com idade média de 70 ± 12 anos e 92,9% com IAM com supradesnivelamento do segmento ST. O endpoint primário ocorreu em 47,8% dos doentes do grupo 1 e em 37,5% do grupo 2-3 (p = 0,359). As taxas de mortalidade intra-hospitalar, reinfarto, acidente vascular cerebral e hemorragia major foram também semelhantes nos dois grupos. Os preditores de mortalidade intra-hospitalar nesta amostra foram a presença na admissão de disfunção ventricular esquerda (OR 16,8), bloqueio completo de ramo direito (OR 7,6) e anemia (OR 5,2), (p ≤ 0,02). Conclusões: Entre os doentes com IAM, CC e DMV, incluídos no RNSCA, não se verificou diferença significativa entre revascularização completa no evento índex e completa diferida ou incompleta durante o internamento, relativamente à ocorrência de morte intra-hospitalar ou reinfarto.

Abstract Background: In patients with acute myocardial infarction (MI), cardiogenic shock (CS), and multivessel disease (MVD) questions remain unanswered when it comes to intervention on non-culprit arteries. Objective: This article aims to 1) characterize patients with MI, CS and MVD included in the Portuguese Registry on Acute Coronary Syndromes (ProACS); 2) compare different revascularization strategies in the sample; 3) identify predictors of in-hospital mortality among these patients. Methods: Observational retrospective study of patients with MI, CS and MVD included in the ProACS between 2010 and 2018. Two revascularization strategies were compared: complete during the index procedure (group 1); and complete or incomplete during the index hospitalization (groups 2-3). The primary endpoint was a composite of in-hospital death or MI. Statistical significance was defined by a p-value <0.05. Results: We identified 127 patients with MI, CS, and MVD (18.1% in group 1, and 81.9% in groups 2-3), with a mean age of 7012 years, and 92.9% of the sample being diagnosed with ST-segment elevation MI (STEMI). The primary endpoint occurred in 47.8% of the patients in group 1 and 37.5% in group 2-3 (p = 0.359). The rates of in-hospital death, recurrent MI, stroke, and major bleeding were also similar. The predictors of in-hospital death in this sample were the presence of left ventricle systolic dysfunction on admission (OR 16.8), right bundle branch block (OR 7.6), and anemia (OR 5.2) (p ≤ 0.02 for both). Conclusions: Among patients with MI, CS, and MVD included in the ProACS, there was no significant difference between complete and incomplete revascularization during the index hospitalization regarding the occurrence of in-hospital death or MI.

Factores neurológicos asociados a la mortalidad en pacientes con accidente cerebrovascular y ventilación mecánica artificial / Neurological factors associated to mortality in patients with cerebrovascular accident and artificial mechanical ventilation

Introducción: El accidente cerebrovascular es una de las causas más comunes de mortalidad a nivel mundial. Objetivo: Determinar la asociación existente entre el desarrollo de afecciones neurológicas y la necesidad de ventilación mecánica con el aumento de la incidencia de mortalidad en la unidad de cuidados intensivos. Métodos: Estudio observacional, prospectivo de corte transversal, realizado en la unidad de cuidados intensivos de un hospital de atención secundaria. La población de estudio estuvo constituida por 52 pacientes con accidente cerebrovascular los cuales recibieron soporte respiratorio artificial entre los años 2018 y 2020. La variable de interés final fue la mortalidad. Los factores neurológicos estudiados fueron el tipo de accidente cerebrovascular, puntuación de la escala de coma de Glasgow, ausencia de reflejos de tallo encefálico, anisocoria y complicaciones neurológicas. El nivel de significación se halló según p valor ≤ 0,05 a través de Chi cuadrado de independencia. Resultados: La mortalidad proporcional predominó en el accidente cerebrovascular hemorrágico tipo hemorragia intracraneal no traumática (p= 0,118), ausencia de reflejos del tallo encefálico (p=0,000), anisocoria (p=0,000), escala de coma de Glasgow <8 puntos (p=0,000) y complicaciones neurológicas como la hipertensión endocraneana (p=0,010). Conclusiones: Los factores neurológicos asociados a la mortalidad fueron la ausencia de reflejos del tallo encefálico, anisocoria, escala de coma de Glasgow <8 puntos y complicaciones neurológicas como la hipertensión endocraneana(AU)

Introduction: Cerebrovascular accident is one of the commonest causes of mortality in the world. Objective: To determine the association between development of neurological disorders and the need for mechanical ventilation with an increased incidence of mortality in the intensive care unit. Methods: An observational, prospective and cross-sectional study was carried out in the intensive care unit of a secondary care hospital. The study population consisted of 52 patients with cerebrovascular accident who received artificial respiratory support between 2018 and 2020. The final variable of interest was mortality. The neurological factors studied were type of cerebrovascular accident, score according to the Glasgow coma scale, absence of brainstem reflexes, anisocoria, and neurological complications. The level of significance was determined according to P ≤ 0.05, through chi-square of independence. Results: Proportional mortality prevailed in hemorrhagic cerebrovascular accident of nontraumatic intracranial hemorrhage type (P=0.118), absence of brainstem reflexes (P=0.000), anisocoria (P=0.000), score of less than eight points according to the Glasgow coma scale (P=0.000), and neurological complications such as endocranial hypertension (P=0.010). Conclusions: The neurological factors associated with mortality were absence of brainstem reflexes, anisocoria, score of less than eight points according to the Glasgow coma scale, and neurological complications such as endocranial hypertension(AU)
