Endovascular treatment of ruptured anterior communicating artery aneurysms. Results and technical considerations.

ABSTRACT

SUMMARY: The aim of this paper is to provide a review of our experience in using the endovascular treatment of ruptured anterior communicating artery (ACoA) aneurysms. Between March 1997 and May 2004, 211 ruptured aneurysms were treated with Guglielmi detachable coil (GDC) system in Mito Medical Center, 73 were located at the ACoA.Two cases were incomplete embolization, and performed microsurgical clipping. In the initial embolization for the 71 aneurysms, complete occlusion was achieved in 44 aneurysms, neck remnant in 11 aneurysms and body filling in 16 aneurysms. Intra-operative complication was occurred in six cases (8.2%). Aneurysm perforation was occurred in three cases (4.1%), thromboembolic complication was occurred in three cases (4.1%). Acute rebleeding were observed in two cases (2.7%). Endovascular treatment is an effective technique for treating ACoA aneurysms, and 3D-rotational angiography is important diagnostic tool for evaluating the ACoA complex.
