Nineteen patients with intracranial aneurysm were treated using electrically detachable coils (GDC or IEDC) and angiographic results and complications were assessed. In 18 aneurysms treated by endosaccular occlusion, 11 (61%), 3 (17%) and 4 (22%) resulted in complete occlusion, neck remnant and dome filling, respectively. Neither haemorrhagic nor thromboembolic complications occurred in 19 patients. Embolization using electrically detachable coils seemed to be a safe and useful procedure without complications, but we should give attention to avoiding complications and incomplete occlusion in particular in a case of 1) wide-necked, 2) small (> 3 mm) or 3) complex-shaped aneurysms.
