Cerebral aneurysm in patients suffering from spontaneous subarachnoid hemorrhage in southern Iran

Background: Subarachnoid hemorrhage (SAH) due to cerebral vessels aneurysm is a fatal disease with high mortality. Regarding the high mortality of the disease, this study was performed to evaluate the etiology, epidemiology, clinical manifestation, aneurysm and the diagnosis of the disease. Methods: 132 patients with SAH who were admitted in Neurosurgery Department of Nemazee and Beheshti hospitals affiliated to Shiraz University of Medical Sciences in Shiraz during September 2002 to March 2006 were evaluated for the mentioned factors. Results: Sixty-eight patients (51%) suffered from cerebral aneurysm among whom anterior common artery (33.8%) and middle common artery (23.5%) were more involved with aneurysm. Finally, 58.3% of the patients were completely treated, 19.6% were discharged with complications in spite of various treatment efforts and 21.9% expired. Conclusion: Regarding the high mortality of SAH due to aneurysm of cerebral vessels and considering various treatments measures, one third of patients still would experience the hemorrhage again. Therefore, attention to early diagnosis of the disease seems necessary.
