Abstract:
Objective To study the methods and results of endovascular treatment of posterior inferior cerebellar artery (PICA) aneurysms. Methods Twenty-one patients with PICA aneurysms were treated with endovascular treatment. The locations of aneurysm on PICA were evaluated through the DSA. Eight patients received single coil embolization, 5 received liquid Glue embolization, 2 received coil embolization combined with liquid Glue, 2 received coil embolization assisted with stents, and 4 underwent ocelasion of the parent PICA. Outcome was evaluated with the Glasgow outcome scale (COS). Results There were complete (100%) occlusion in 5 patients, near complete (>90% ) occlusion in 2, and incomplete (85%) occlusion in 1 in single coil embolization. Seven patients with Glue embolization (n = 5 ) or combination with coils ( n = 2 ) exhibited complete ( 100% ) occlusion. There were near complete ( >90% ) occlusion in 2 cases with coil assisted with stents. Complete occlusion of the parent PICA was achieved in 3 patients, and near complete occlusion of PICA in one case. One patient suffered from new neurological deficits, and one patient treated with coils and stents died. None of the patients suffered from re-bleeding. These patients received follow-up during a mean period of (22±8) months. Overall long-term outcome was good ( GOS score 4 or 5 ) in 17 patients, poor ( COS score 2 or 3) in 3, and fatal ( GOS score 1 ) in one case. Conclusions According to the location of aneurysms on PICA, aneurysms can be effectively and safely treated with endovaecular embolization.
