IDC Embolization of Aneurysms

Embolization using IDC was carried out for 33 aneurysm cases in the last 3 years. The indication for the embolization was that the direct surgery was considered to be difficult, because of 1) technically impossible to do clipping, 2) aneurysm of the posterior fossa, 3) reject of patients. Regarding the location of aneurysm, 27 cases were seen in the anterior circulation, and 6 cases in the posterior circulation. Count of 33 cases, 11 cases were ruptured and 22 cases were non-ruptured. The procedure of embolization of aneurysms are generalized as compared to direct surgery, but there remain some technical problems. 33 cases in our series had no significant complication, except for one which had ruptured again. We emphasize that the weak point of IDC which was so hard, had no variations, especially if it happens to migrate during locking procedure. These complications can be prevented, if we use GDC(5,6,7) instead of IDC.
