[Endovascular treatment of posterior cerebral artery aneurysm: analysis of 21 patients].
OBJECTIVE
To investigate the effect of endovascular treatment on posterior cerebral artery (PCA) aneurysm.


METHODS
The clinical data of 21 patients with PCA aneurysm, 12 males and 9 females, aged 3 - 60, totally 22 aneurysms, 3 located in the P1 segment, 16 (in 15 patients) on the P2 segment, and 3 being serpentine aneurysms and involving P2-3 segment, were analyzed. One patients gave up treatment, 6 patients, with 7 aneurysms, underwent aneurysm sac occlusion, and 14 patients underwent parent vessel occlusion.


RESULTS
Complete aneurysm sac occlusion was achieved in 5 patients with 6 aneurysms, and incomplete occlusion was achieved in 1 patient who died of bleeding of aneurysm the next day after the operation. All 14 patients undergoing parent vessel occlusion survived without aneurysm detected by angiography, among which 3 presented hemianesthesia of the contralateral side and 2 recovered completely.


CONCLUSIONS
Endovascular treatment is safe and effective for PCA aneurysm.
