Spontaneous dissecting aneurysm of the vertebral artery is an infrequent cause of vertebro basilar ischemic strokes. Previously reported cases concern essentially occlusion of the basilar artery. Only 14 cases of spontaneous dissecting aneurysm concern the extracranial vertebral artery among these eight were angiographically documented. In this study based upon 15 patients (20 dissecting aneurysms), the authors discuss etiological factors, such as hypertension or fibromuscular dysplasia: on clinical findings they insist upon the diagnostic value of preliminary symptoms, cervical pain or posterior headaches; the most frequent angiographic appearance was a long and irregular stenosis of one or two segments of the vertebral artery. The prognosis of these aneurysms most often appears favourable in this group.
椎动脉自发性夹层动脉瘤是椎基底动脉缺血性卒中的罕见病因。先前报道的病例主要涉及基底动脉闭塞。在这些病例中，仅有14例自发性夹层动脉瘤累及颅外椎动脉，其中8例有血管造影记录。在这项基于15例患者（20个夹层动脉瘤）的研究中，作者讨论了病因学因素，如高血压或纤维肌发育不良；在临床发现方面，他们强调了首发症状、颈部疼痛或后头痛的诊断价值；最常见的血管造影表现是椎动脉一段或两段的长而不规则狭窄。在这组病例中，这些动脉瘤的预后大多良好。
