Angiographic Findings in Patients with Ruptured Cerebral Aneurysm

Cerebral aneurysms are of clinical importance regarding their fetal outcomes. The prevalence has been estimated between 2.4% and 6.8% of outopsies. Regarding the epidemiological differences of populations, the present cross-sectional study was undertaken to assess the angiographic findings of ruptured aneurysms. 50 patients with the diagnosis of ruptured cerebral aneurysms were admitted to Haftom-e-Tir Hospital in Tehran, from 2001 to 2002. Data about sex, age, risk factors, clinical presentations and angiographic findings of DSA(site, size and number of lesions) were collected and analysed via SPSS 11.5 software (presuming α=0.05). Mean age was 52±3.4 and 52% of the patients were women. Hypertension(65.3%) was the most prevalent risk factor. 64% of the patients suffered from headache and 58% presented with loss of consciousness. The first ranked site of aneurysms was Anterior Communicating Artery(63%). The mean size was 6.9±0.9mm(±2SE). 60% of aneurysms were of 6-10mm size and 8% of patients had multiple aneurysm. The findings of this study about sex, site, size and risk factors, are in accordance with other studies. Higher prevalence of aneurysms in patients younger than 30 years old, fewer cases with multiple aneurysms and more than half of patients with loss of consciousness are the main considerable differences.
