Endovascular treatment of intracranial aneurysms using plantinum coils was performed in 10 patients over 80 years of age. The patients ranged in age from 81 to 96 years. Preoperative Hunt and Kosnik grading revealed one patient in grade I, 4 in grade II, 3 in grade III, and 2 in grade IV. The aneurysms were located in the internal carotid artery in 6 patients, in the anterior communicating artery in 1, and in the middle cerebral artery in 3 respectively. Intra-aneurysmal occlusion was accomplished in 8 patients with total or subtotal occlusion in 6 and partial occlusion in 2. In one patient with a peripheral middle cerebral artery aneurysm, the parent artery was occluded just proximal to the aneurysm. In the remaining one patient in grade III, an aneurysm associated with wide neck could not be occluded because of coil protrusion into the parent artery. In 9 patients who were successfully treated, all five patients in grade I or II and one in grade III resulted in good outcome, but the other three patients in grade III and IV showed poor outcome. No evidence of recurrent hemorrhage was noted during the follow-up period ranging from 2 months to 4 years. Endovascular coil embolization is a useful therapeutic alternative for treating ruptured intracranial aneurysms in patients over 80 years of age, especially those in Grade I or II.
