Abstract
Objective The purpose of the current study was to evaluate the methods and results of endovascular treatments for distal posterior cerebral artery (PCA) aneurysms. Methods Over 5 years we studied 10 patients admitted to our hospital, of 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. Different strategies were used, depending on the locations and shapes of the aneurysms. Specifically, 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 were used for dissenting aneurysms at the P3 segment. Results Postoperative follow-up in 9 patients demonstrated that these treatments achieved good recovery; one patient was lost. All the aneurysms had no recurrence in the follow up of DSA.Conclusion Taken together, 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. Key words: Intracranial aneurysm; Distal posterior cerebral artery; Endovascular treatment
