Résumé
Objective To investigate the effect of endovascular treatment of vertebral basilar artery dissecting aneurysms. Methods The clinical data of 40 patients with vertebral basilar artery dissecting aneurysm admitted to Beijing Xuanwu Hospital and Haidian hospital,Capital Medical University from August 2013 to September 2014 were analyzed retrospectively. Their clinical symptoms and imaging were followed up. According to the treatment methods,they were divided into either a stent-assisted coil emboliza-tion group (group A;n = 34)or a parent artery occlusion (group B;n = 6),and according to the clinical symptoms and imaging followed-up,the efficacy was assessed at 1 year after procedure. Results The patients were followed up for 1 year after procedure,29 patients (85. 3%)were improved in group A, 1 (2.9%)was stable,and 4 (11. 8%)deteriorated. All the 4 deteriorated patients died of cerebral infarction complications (at 1 week to 6 months after procedure). The 6 patients in group B were improved compared with before procedure. No intracranial hemorrhage and ischemic events occurred. Conclusion Using the stent-assisted coil embolization technique and the parent artery occlusion technique for the treatment of the vertebral basilar artery dissecting aneurysms are relatively safe and effective.
