Endovascular treatments for distal posterior cerebral artery aneurysms

The purpose of the current study was to evaluate the methods and results of endovascular treatments for distal posterior cerebral artery (PCA) aneurysms.

We studied 10 patients admitted to our hospital, of which 6 had aneurysms at the P2 segment (2 were saccular, 2 were fusiform, 2 were dissecting), 1 had a dissecting aneurysm at the P2-P3 junction and 3 had dissecting aneurysms at the P3 segment. Coil embolization was used for saccular aneurysms to retain parent arteries, stent was used for fusiform aneurysm to reconstruct the parent arteries, coil embolization in combination with parent artery occlusion was used for dissecting aneurysms at P2 segment or P2-P3 junction, aneurysm embolization in combination with parent artery occlusion by Glubran glue was used for dissenting aneurysms at the P3 segment.

Nine patients got a score of 5, one patient got a score of 4. DSA follow up in nine accepted the review (one patient with fusiform aneurysm at the P2 segment was lost). No reoccurrence was found.

The results of this study suggested that to achieve a satisfying prognosis, the types and locations of the aneurysms should be considered when performing the endovascular treatment for distal PCA aneurysms.
