Surgical treatment of giant intracranial aneurysms.

The authors report the cases of 32 patients with aneurysms measuring 2.5 cm or greater in diameter found among 1080 patients with saccular cerebral aneurysms. Of the 32 patients, 24 patients were treated by direct operation, four by common carotid ligation, and the other four by conservative therapy. The appropriateness of surgery and surgical method are discussed.
