INTRODUCTION: Patients who have subarachnoid hemorrhage due to aneurysm rupture differ from patients suffering spontaneous nonaneurysmal subarachnoid hemorrhage (SAH) in the aspects of clinical features. METHODS: We investigated retrospectively the demographic and clinical features of our patients with aneurysmal and nonaneurysmal SAH. The characteristics of the aneurysms including localization and size, and their relation with the severity of the hemorrhage by Fisher score were also evaluated. RESULTS: Our study included 205 SAH patients who were divided into two groups: aneurysmal (n: 130) and nonaneurysmal (n: 75). The demographic characteristics, comorbidities, drug usage and clinical profiles of patients showed no difference. World Federation of Neurological Surgeons (WFNS) SAH grading (4.02±1.44 vs. 2.84±1.34, p=0.00) and Fisher scores (2.78±0.97 vs. 2.25±0.85, p=0.00) were found higher in aneurysmal SAH and the anterior communicating artery was the most common site of the aneurysms (n: 41, 20%). The size, diameter, neck and diameter-neck ratio of aneurysm had no effect on the severity of hemorrhage. In patients with hypertension, WFNS and Fisher scores were higher than in nonhypertensives. DISCUSSION AND CONCLUSION: We found higher WFNS and Fisher scores in aneurysmal SAH, and also in patients with accompanying hypertension. Most ruptured aneurysms were detected in the anterior communicating artery. The location and size of the ruptured aneurysm had no effect on bleeding severity.
