“…The distribution shown by the patients studied in the 40 to 60 year range is similar to that reported by the Comparative Study (50.3%) 7 , but if we consider the distribution below 40 years and above 60 years there was a significant difference (32% for the present patients and 19.2% in the Comparative Study for the less than 40 age group, and 20.4% for the present patients and 30.4% in the Comparative Study for the over 60 age group). This difference may be explained by the shorter mean life expectancy for our population in relation to the North American one.…”

“…In the group of patients with hemorrhage due to other causes there was no significant difference in distribuition by sex, except for female predominance during the third decade (2.2:1) and for male predominance during the fourth decade (1.7:1). Overall distribution was similar to that reported by the Cooperative Study 7 but there was a difference in distribution by decade of life (male predominance below 20 years and female predominance above 70 years).…”

“…The frequency of ruptured aneurysms as a cause of subarachnoid hemorrhage was lower in the present series than in the population surveyed by the Cooperative Study (51 %) 7 , and among the other causes we observed only one case of hemorrhage due to rupture of an arteriovenous malformation, in contrast to the 6% frequency reported by the Cooperative Study 7 . This difference may be explained by the fact that the present population consisted only of patients who died due to hemorrhage.…”

“…Even though overall distribution of the present cases was similar to that reported by the Cooperative Study 7 , distribution by decade of life was different since the Cooperative Study reported male predominance during the first four decades.

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...

ABSTRACT:We analysed the charts of 131 consecutive cases of spontaneous subarachnoid hemorrhage -without arteriovenous malformations -for seizures. Convulsions occurred in 31 patients (24%) and most often within 24 hours of bleeding. Motor manifestations of partial seizures were of no lateralizing value to aneurysm site. Early mortality, rebleeding and intracerebral hematoma were similar in both seizure and non-seizure groups. Late seizures were infrequent in survivors who had suffered seizures in the acute stage -thus questioning the necessity for routine, long term prophylactic anticonvulsants in these patients. RESUME: Convulsions associees a une hemorragie sous-arachnoidienne. Nous avons analyse les dossiers de 131 cas consecutifs d'hemorragie sous-arachnoidienne spontanee -sans malformation arterio-veineuse -pour determiner la presence ou I'absence de convulsions. Trente-et-un patients ont presente des convulsions, le plus souvent en dedans de 24 heures de I'hemorragie. Les manifestations motrices des crises partielles n'avaient pas de valeur quant a la lateralisation du site de l'anevrisme. La mortality precoce, I'hemorragie subsequente et I'hematome intracerebral dtaient aussi frequents dans les deux groupes, soit avec convulsions et sans convulsion. Les convulsions d'apparition tardive etaient rares chez les survivants qui avaient souffert de convulsions a la phase aigue -remettant ainsi en question la necessite de prescrire de routine des anticonvulsivants a long terme chez ces patients.Can. J. Neurol. Sci. 1986: 13:229-231 Spontaneous subarachnoid hemorrhage (SSH) is a common neurological disorder and accounts for approximately 10% of all strokes.1 ' 2 Complications such as rebleeding, vasospasm and hydrocephalus are well recognized and there is extensive literature on these topics. However, the subject of seizures in SSH has not attracted as much attention. Pioneer monographs 3 "" and more recent large studies 12 " 15 on SSH fail to discuss seizures in detail or make only brief comments on this complication. This is particularly evident for SSH not associated with arteriovenous malformations (AVM). We are aware of only 6 reviews' 6 " 21 in world literature (4 English, I Serbo-Croatian and I Chinese), about seizures in SSH of non-AVM etiology. In this paper, we analyse the following aspects: i) incidence, type and time of convulsions, ii) seizure laterlizing value for aneurysm site, iii) could intracerebral hematoma cause seizures, iv) do seizures affect early rebleeding and mortality and v) the need for longterm prophylactic anticonvulsants for patients who have suffered seizures in the acute stage. METHODSSpontaneous subarachnoid hemorrhage was defined as an acute neurological event leading to the presence of blood in subarachnoid space, confirmed by CT scan or/and cerebrospinal fluid examination in the absence of trauma. Cases associated with neonatal hypoxic encephalopathy, primary hypertensive intracerebral hematoma, cerebral and spinal vascular malformations, and those with chronic idiopathic ...
