Endovascular Treatment of Intracranial Aneurysms with Electrically Detachable Coils
The recent development of electrically detachable coils by Guglielmi  has given a new perspective to the treatment of aneurysms. It has extended and improved previously used occlusion techniques with detachable balloons or freely removable coils through two essential advantages: (a) the direct current applied for detachment induces an intra-aneurysmic electrothrombosis, and (b) the placement of the coils in the aneurysm is reversible through angiographic control, at any time until the actual detachment. Because variable sizes (3–12 mm) and lengths (8–20 cm) of coils can be selected, this system can be utilized for extreme aneurysm sizes, from giant ones down to microaneurysms with a diameter of 3 mm. This brief report summarizes our initial experience with the Guglielmi detachable coil (GBC) in endovascular approach of experimentally created aneurysms and in the first 18 patients.
