ABSTRACT
The intracranial hematoma following cerebral aneurysmal rupture makes patient's clinical status and outcome worse by pressure effect on the brain structure. It's incidence has varied with authors between 5-30% of patients with ruptured cerebral aneurysms. Several authors emphasized the importance of early operation to obtain better results by early removal of hematoma and reducing intracranial pressure. The authors retrospectively evaluated seventy-six patients with intracranial hematomas in 370 patients with ruptured aneurysms from Jan. 1987 to Dec. 1992. The incidence of hematoma resulting from ruptured aneurysm was 20.5%. The most frequent site of aneurysm which was accompanied by intracranial hematoma was the middle cerebral artery, and the next was the anterior cerebral artery. The amount of hematoma and/or evidence of midline shift were the important factors in predicting the clinical outcome. The most favorable outcome was found in cases with intracerebral hematoma only, and the worst was in cases with intracerebral hematoma associated with intraventricular hemorrhage. Fifty out of 76 patients with intracranial hematomas were operated on. Their outcomes were more favorable than in the patients who were not operated on. Aggressive surgical intervention was especially effective in patients with poor Hunt & Hess grades(IV or V) .
Key Words: Ruptured intracranial aneurysm; Intracerebral hematoma; Intraventricular hemorrhage; Early surgery
