[Endovascular occlusion of intracranial aneurysms using the "Guglielmi Detachable Coil"].

Thirty-seven patients with 42 sacculate intracranial aneurysms of delicate location were treated, or attempted treated, with Guglielmi Detachable Coils (GDC) from July 1994 through December 1995. Intended aneurysm occlusion was not achieved in five patients (five aneurysms) due to unfavourable anatomy. In two additional cases the procedure was interrupted because of complications. In 31 patients (35 aneurysms) the aneurysms were successfully occluded. So far 16 patients (19 aneurysms) have undergone angiography six months postoperatively, and four of five partly recanalized aneurysms were reoccluded. Two patients died following a major complication, and five patients recovered following a minor complication to the procedure. A total of 39 procedures were uncomplicated, and the patients recovered uneventfully. In conclusion, endovascular occlusion with GDC of intracranial aneurysms of delicate location is a promising innovative procedure.
