Abstract:
Objective To investigate the feasibility and effectiveness of endovascular treatment of posterior communicating artery aneurysm (PcoAA)in keeping the fetal posterior cerebral artery (FPCA) patency. Methods Form January 2014 to December 2015,14 patients with ruptured PcoAA enrolled retrospectively were treated with endovascular embolization. Six of them were treated with simple coil embolization,3 with stent-assisted coil embolization,3 with double catheter-assisted coil embolization,1 with stent-assisted coil embolization + double catheter technique,and 1 with Y-stent in Yijishan Hospital, Wannan Medical College. The immediate embolization rate of PcoAA (using Raymond grade),prognosis of the patients (the modified Rankin scale score at 6 months after procedure),complications,and imaging follow-up results were analyzed. Results The success rate of coil and stenting was 100% . All the stents were accurately released in place without displacement. The immediate Raymond grading of the aneurysms displayed that Raymond grade Ⅰ was in 8 cases,Raymond grade Ⅱ was in 4 cases,and Raymond grade Ⅲ was in 2 cases. All FPCA were kept patent. A coil protruded into internal carotid artery in one case during the procedure. Others did not have any complications,such as intraoperative cerebral vasospasm,in-stent thrombosis,and rupture. All 14 patients were followed up for 3 -24 months after procedure. Two had recurrence. Both were aneurysms embolized with coils only. No rebleeding and ischemic
complications were observed. The modified Rankin scale scores in 13 cases were 0 -2 at 6 months after procedure,1 was 4. Conclusions Endovascular embolization for the treatment of PcoAA and keeping FPCA patency are safe and feasible. A variety of endovascular treatment modalities are necessary in order to keep FPCA patency.
