Abstract: | Sex-related differences were examined in the clinical course of patients treated surgically for aneurysmal subarachnoid hemorrhage. Retrospective analyses were carried out to evaluate sex-related differences in aneurysm location, aneurysm size, preoperative neurological condition, preoperative computed tomography findings, and outcome among 2577 patients who underwent surgical repair of ruptured aneurysms. The internal carotid artery was most frequently affected in women and the anterior cerebral artery in men. Intracerebral or intraventricular hematoma was more common in men than in women. Some differences may be related to the location of the aneurysm. Sex-related differences were prominent in the 5th decade of life. These findings might be related to the menopause. Sex hormones may be involved in aneurysm formation. |
