Thirty four cases of bilateral hematoma (14%) out of 248 cases of acute traumatic intracranial hematoma are reported with regards to clinical analysis and therapeutic problems.
Operative results of the bilateral hematomas were the worst among various intracranial hematomas because of severe preoperative conditions and bilateral brain damage. Bilateral hematomas had no specific clinical features in comparison with unilateral hematomas. It was difficult to diagnose them by symptoms alone.
The validity of Nelson and Freimanis method of differential diagnosis between unilateral hematoma and bilateral hematoma based on the shift of anterior cerebral artery during unilateral cerebral angiography was checked. Fifteen cases out of 25 cases of bilateral hematoma angiographically showed over 51 % shifts of the anterior cerebral artery. This was quite different from the report by Nelson and Freimanis.
