A retrospective hospital chart and radiograph review was performed of 720 cerebral aneurysm operations between April, 1978, and December, 1985. Of these patients, three cases (0.4%) had rebleeding of non-operated cerebral aneurysms in hospitalization after surgical treatment. In these cases, preoperative angiograms were reviewed after ruptured aneurysms were identified, but we could not determine that the rebleeding aneurysms were the ruptured aneurysms.
It is necessary that we always consider the possibility of multiple cerebral aneurysms. We must examine the shapes of the aneurysms, operative features, and the relation between the locations of the aneurysms and the extent of subarachnoid hemorrhage. When in doubt as to whether the aneurysms is ruptured or not, it is necessary that we sufficiently investigate other aspects of the aneurysms, such as an unusual site.
