Cerebromeningeal hemorrhage: analysis of autopsies performed over a 10-year period

Abstract

SUMMARY -A study was conducted on the medical records of 353 patients who died of a subarachnoid hemorrhage (SAH) and who were submitted to autopsy over the last 10 years. SAH was associated with arterial hypertension in 180 (51%) cases, with ruptured aneurysms in 102 (28.9%), and with other pathologies in 71 (20.1%). The patients with hemorrhage associated with arterial hypertension were mostly males, and those with hemorrhage due to aneurysms were mostly females. Of the patients with aneurysms, 36 (35.3%) had aneurysms in the anterior communicating artery, 30 (29.4%) in the internal carotid artery, and 23 (22.6%) in the middle cerebral artery. Among the patients with aneurysms who suffered rebleeding and vasospasm, 59.1% and 61.5%, respectively, were classified as grade I and II upon admission, and all evolved toward grade IV after these complications, Vasospasm predominated from the 3rd to the 10th day after hemorrhage, and rebleedine from the 9 to 16th day and both were most frequent among patients with aneurysms of the anterior communicant artery. Sixty eight percent of the patients with aneurysms died during the first 9 days after hemorrhage. Because of our conduct was to operate systematically late, a considerable number of patients lost the oportunity to be treated surgically with possible favorable evolution due to vasospasm or rebleeding.Hemorragia cerebromeníngea: análise de autópsias em período de 10 anos.RESUMO -Foram analisados 353 pacientes que faleceram por hemorragia subaracnóidea autopsiados nos últimos 10 anos no Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto. A hemorragia subaracnóidea estava associada a hipertensão arterial em 180 casos, a ruptura de aneurismas em 102 e a outras patologias em 71 casos. O sexo masculino predominou nos pacientes com hemorragia associada a hipertensão arterial e o feminino nas hemorragias por ruptura de aneurismas. As hemorragias associadas a hipertensão arterial predominaram em faixas etárias mais altas em relação às hemorragias por aneurismas. Dos pacientes com aneurismas, 36 (35,3%) apresentaram aneurismas no complexo cerebral anterior/comunicante anterior, 30 (29,4%) na carótida interna e 23 (22,5%) na cerebral média. Nos casos de aneurismas, o vasoespasmo predominou no período do 3 o ao 10 o dia e o ressan-¬ gramento predominou no período do 9 o ao 16 o e respectivamente 59,1% e. 61,5% desses pacientes apresentaram-se nos graus I e II na admissão e evoluíram para o grau IV após estas intercorrências. Ambas as intercorrências foram mais freqüentes entre os pacientes com aneurismas do complexo cerebral anterior/comunicante anterior.Sessenta e oito por cento dos óbitos por aneurismas ocorreram nos 9 primeiros dias após a hemorragia. Os pacientes admitidos em grau I e II e que sofreram vasoespasmo ou ressangramento e que poderiam beneficiar-se do tratamento cirúrgico precoce não tiveram esta oportunidade porque a nossa conduta naquela época era de operar sistematicamente no final da segunda ou no início da terceira semana após a hemorragia su...

Cerebral Venous Thrombosis with Subarachnoid Hemorrhage: a Case Report

“…1 However, CVT presenting with an associated subarachnoid hemorrhage (SAH) on computed tomography (CT) and magnetic resonance imaging (MRI) is infrequent. 2,3 SAH is becoming more frequently recognized as a potential complication of CVT.…”

Subarachnoid Hemorrhage: A Rare Presentation of Cerebral Venous Thrombosis

“…Ohta et al 4 described a patient with aplastic anemia presenting a subarachnoid hemorrhage with thrombosis of the superior sagital sinus, and Zakharov and colleagues 5 observed a spontaneous subarachnoid hemorrhage in a woman with an acute thrombus of the lateral sinus. Furthermore, a review of autopsy results of 353 patients who died of a subarachnoid hemorrhage did not demonstrate any case of CVT, suggesting that such an association is rather exceptional 6 …”
