GOLAND, Javier et al. Efectividad del abordaje endovascular en una serie de 122 aneurismas cerebrales del circuito posterior. Rev. argent. neurocir. [online]. 2008, vol.22, n.1. ISSN 1850-1532.

Objective. To describe morbidity and mortality secondary to endovascular treatment in a series of cases with posterior circle aneurysms. Material and Method A descriptive study in a series of adult patients with posterior circle aneurysms treated by endovascular surgery. Results. Endovascular therapy was done in 116 of 122 aneurysms studied by angiography. Posterior circle aneurysms were completely occluded in 73% of cases, basilar tip aneurysms had complete occlusion in 68% of cases, posterior inferior cerebellar artery aneurysms were totally occluded in 72% of cases, superior cerebellar artery aneurysms occlusion was in 82% and vertebral artery aneurysms were occluded in 75% of cases. The 50% of basilar trunk aneurysms were totally occluded and the only anterior inferior cerebellar artery aneurysm treated was fully occluded. Morbidity and mortality related to the technic was 5,2% and 1,7%. Conclusion. In our series of cases, embolization was very effective to approach every types and locations of posterior circle aneurysms with a high rate of complete occlusion with low morbidity and mortality.
