3 patients with intracranial infarctions as consequence of obstructive lesions of the distal vertebral artery are presented. The first patient, with a unilateral occlusion of the distal intracranial portion of the vertebral artery and contralateral high grade stenosis at the same site, suffered bilateral cerebellar infarctions. Predominantly occipital infarction occurred in the second patient, with unilateral occlusion of the vertebral artery, the infarction being probably caused by embolization from the distal stump. In the third patient traumatic injury of the vertebral artery at the C1/C2 level was followed by embolic occipital lobe infarction. The discussion covers pathogenetic significance of hemodynamic and thromboembolic factors for cerebellar and occipital infarctions and the possible therapeutic options.
本文报告了3例因椎动脉远端阻塞性病变导致颅内梗死的患者。首例患者颅内椎动脉远端单侧闭塞，同侧对侧存在高度狭窄，发生双侧小脑梗死。第二例患者椎动脉单侧闭塞，主要发生枕叶梗死，梗死可能由远端残端的栓子脱落所致。第三例患者C1/C2水平椎动脉外伤后发生栓塞性枕叶梗死。讨论内容包括血流动力学和血栓栓塞因素对小脑和枕叶梗死的发病机制意义以及可能的治疗选择。
