Endovascular embolization for posterior cerebral artery aneurysms / 中国脑血管病杂志

ABSTRACT

Objective: To investigate the methods and safety of endovascular embolization for treatment of posterior cerebral artery aneurysms. Methods: Eight patients with posterior cerebral artery aneurysms treated by using endovascular embolization were analyzed retrospectively. The clinical features, method of treatment and prognosis of the patients were summarized. Results: Circled digit oneThere were eight patients with 8 aneurysms. Of those, one aneurysm was located at the P1 segment, 2 were at the P1-P2 segment, 3 were at the P2 segment, and 2 were at the P3 segment. There were 6 patients with fusiform or dissecting aneurysm and 2 with saccular aneurysm. Circled digit twoOne patient was treated by balloon occlusion of parent artery. Five patients were treated by coil packing of the aneurysmal sacs and parent artery occlusion. Two patients were treated by coil packing of the aneurysmal sacs only. Circled digit threeAfter the procedure, DSA showed that all the aneurysms disappeared completely. There were no ischemic symptoms in the six patients with parent arteries occlusion after the procedure. No neurological deficits and other intervention-related complications were found in all the patients. Circled digit fourNo recurrence of the aneurysm was observed under DSA re-examination 3 to 6 months after the procedure. The patients were followed up for 1 to 12 years and all returned to their normal life. Conclusion: Endovascular embolization is a safe and effective therapeutic approach for posterior cerebral artery aneurysms.
