Endovascular occlusion of vessels, most commonly the ICA, offers several advantages over surgical ligation. It can be performed as a single procedure with simultaneous test balloon occlusion on an awake patient, before permanent sacrifice of the vessel is undertaken. Collateral supply can be assessed angiographically at the same time and any residual filling of the aneurysm can be demonstrated. For cavernous segment aneurysms, a trapping technique is usually employed, where the two balloons are placed one just distal to and the second just proximal to the aneurysmal neck, thus trapping the aneurysm. More distal aneurysmal lesions increase the risks of test balloon occlusion, particularly of vessel rupture. In addition, collateral adequacy can be more difficult to assess.
