Answer

In a study of treatment of 25 cases of PCA aneurysm, the authors found that treating PCA aneurysms with microsurgical or endovascular options can achieve comparable outcomes. In this study, endovascular treatment showed excellent anatomical and clinical outcomes for non-mass compressing, non-giant, saccular aneurysms. However, the authors noted that given the propensity for large-giant, dysplastic PCA aneurysms to develop in younger patients, microsurgical competence should be maintained. They also suggested that along with careful evaluation of the anatomic collaterals over the PCA territory, therapeutic parent artery sacrifice may be an appropriate option without adding bypass. There was no mortality in either group. Microsurgical treatment was the primary treatment in 15 aneurysms. Endovascular coil embolization was performed in 6 aneurysms, stent-assisted coil embolization in 2 aneurysms, and endovascular occlusion of the parent artery in 2 aneurysms. [20]
