Abstract We observed 23 pacients with clinical hypothesis of subarachnoidal hemorrhage (SAH) having cranial tomography (CT) without bleeding signals. The final diagnosis of SAH was made upon the cerebrospinal fluid (CSF) results. Twenty cases were submitted to brain angiography. They were focused under the clinical classification of Hunt & Hess. The main results were: 1) 1/3 of patients had interval time between 24 and 48 hours after ictus and before CT and CSF making; this was the most sensitive CT time; 2) 55% of patients with brain angiography had aneurysm predominantly in the carotid and anterior cerebral artery territory; 3) the dominant clinical degree was Hunt & Hess I e II. Conclusion: the results demonstrate the need of CSF test in case of SAH clinical diagnosis with CT showing no bleeding signals.

Foram observados 23 casos de pacientes com suspeita clínica de hemorragia subaracnoídea (HSA), com tomografia de crânio (CT) sem sinais de sangramento, com diagnóstico definitivo realizado por exame de líquido cefalorraquiano(LCR). Desses, 20 casos foram submetidos a angiografia cerebral. Estabeleceu-se a classificação clínica de Hunt & Hess. Os principais achados neste estudo foram:1) um terço dos pacientes apresentou intervalo de tempo entre o ictus e a realização da CT e do LCR entre 24 e 48 horas, período de maior sensiblidade da CT; 2) dos pacientes estudados com angiografia cerebral, 55% tiveram o diagnóstico de aneurisma com predomínio no território de carótida e cerebral anterior; 3) o grau clínico dominante foi Hunt & Hess I e II. Todos os achados encontrados demonstraram a necessidade da realização de LCR em suspeita de HSA sem sinais de sangramento na CT.
