Endovascular Coil Occlusion of Ruptured Saccular Cerebral Aneurysms Using Guglielmi Detachable Coils

We reviewed the medical records and angiographic films of 83 consecutive patients treated with endovascular GDC occlusion for a saccular cerebral aneurysm following SAH from 1991-2000 (figure 1). The treated aneurysm was felt to be the source of SAH in every case. All procedures were performed at a single institution, by a single endovascular surgeon. Patients with aneurysms arising as a result of trauma or dissection were not considered, nor were patients with mycotic or fusiform aneurysms. Only patients in whom one or more GDCs were actually detached were considered. Patients who underwent GDC occlusion of aneurysms following an incomplete previous surgical clipping or incomplete previous GDC occlusion elsewhere were excluded. In 21 patients with multiple aneurysms, only the aneurysm thought Introduction
