Abstract

Interventional neurovascular treatment of giant intracranial aneurysms is now being performed in selected cases utilizing detachable balloons, microcoils, and electrolytic detachable coils. Of the 321 cases treated by interventional techniques by our group, 95 (29.6%) were giant aneurysms, > 2.5 cm in diameter. In 74 cases, the aneurysm was on the anterior circulation, and in 21 involved the posterior circulation. The patients presented with mass effect in 81 cases (85.3%), subarachnoid hemorrhage in 11 (11.6%), and thromboemboli in 3 (3.1 %). In 64 cases (67.4%), the aneurysm was treated by parent vessel occlusion, and in 31 (32.6%), direct treatment of the aneurysm with preservation of the parent artery was attained. Complications related to treatment included 11 cases (11.6%) of stroke, transient cerebral ischemia in 6 (6.3%), and 9 deaths (9.5%). Treating giant intracranial aneurysm is technically feasible by interventional techniques. Continued advances in endovascular therapy should expand the indications and decrease associated morbidity.
