Análise epidemiológica da hemorragia subaracnóidea espontânea no serviço de neurocirurgia do Hospital de Clínicas da Universidade Federal de Uberlândia

Abstract

Objective: The objective of the present study was to perform an epidemiological analysis of spontaneous subarachnoid hemorrhage (sHSA) in patients attended at our service during the period of one year, and compare this series with the current literature to outline the epidemiologic profile in the area covered by our hospital. Materials and methods: During the study period, sSAH cases admitted to our service were monitored by collecting information consistent with epidemiology, case management and outcome, which were analyzed and compared with those in the current literature. Resultados: We included 33 cases of sSAH with a calculated incidence of 2.64 cases per 100,000 inhabitants per year. The number of females was 3.7 times higher than males. The mean age of the patients was 50.84 years. Overall mortality was 30.30%. Among the cases followed up, 51% presented multiple aneurysms at angiography. Evolutionarily, 54% f the survivors presented severe neurological sequelae and 46 had functional independence at the time of hospital discharge. Conclusions: Our department, in its general aspects, attends to series of cases similar to the literature. The results presented, however, peculiarities such as low incidence, high female proportion and high incidence of multiple aneurysms. In addition, we conclude the continuous need for improvements in the management of this complex nosological entity.
