Abstract:
Objective To analyze stenting and dual catheter technique in protection of posterior inferior cerebellar artery and its imaging and clinical follow-up results in the endovascular treatment of vertebral artery dissecting aneurysms. Methods From January 2012 to December 2014,the clinical data of 4 patients with vertebral artery dissecting aneurysm involving posterior inferior cerebellar artery treated with endovascular method and admitted to the Department of Neurosurgery,Xuanwu Hospital,Capital Medical University were enrolled retrospectively. The whole brain DSA examinations were performed at 6 months after procedure. The clinical follow-up period ranged from 12 to 24 months. Results Three of the 4 patients were treated with posterior inferior cerebellar artery-vertebral artery stenting,one patient was treated by using bidirectional dual catheter technique to protect posterior inferior cerebellar artery. The interventional therapy of 4 patients were all successful. Immediately after procedure,angiography revealed that the posterior inferior cerebellar arteries were patent,no ischemic symptoms were observed. The angiography at 6 months after procedure revealed no recurrence of aneurysms;the posterior inferior cerebellar arteries were patent without in-stent stenosis. No new symptoms of neurological deficit were observed during 12 to 24-month follow-up. Conclusion In the interventional treatment of vertebral artery dissecting aneurysms of posterior inferior cerebellar artery,using the posterior inferior cerebellar artery-vertebral artery stenting technique and bidirectional dual catheter technique may safely and effectively protect the posterior inferior cerebellar artery.
