- Abstract
Aneurysmal subarachnoid hemorrhage (SAH) is a serious disease with high case fatality and morbidity. Early cerebral infarction has been suggested as a risk factor for poor outcome. We aimed to assess the pattern of early and delayed cerebral infarction after aneurysmal subarachnoid hemorrhage. We prospectively enrolled consecutive aneurysmal subarachnoid hemorrhage (SAH) patients presenting to an academic neurosurgical referral center (Prince of Wales Hospital, the Chinese University of Hong Kong) in Hong Kong. Cerebral infarction occurred in 24 (48 %) patients, in which 14 (28 %) had early cerebral infarction and 14 (28 %) had delayed cerebral infarction. Early anterior cerebral infarction occurred in a similar proportion of anterior and posterior circulation aneurysms (24 % vs. 21 %), whereas posterior circulation aneurysm patients had a higher proportion of early posterior cerebral infarction compared with anterior circulation aneurysm patients (18 % vs. 2 %). In conclusion, early cerebral infarction was common and different from delayed cerebral infarction.
