一些与血管内技术椎动脉闭塞相关的并发症已有报道。然而，椎动脉闭塞后小脑出血在亚急性期是罕见的。在这份报告中，我们描述了一个病人谁表现出小脑出血高血压治疗血管痉挛栓塞后的脊椎夹层动脉瘤。一名56岁女性，小脑后下动脉近端椎动脉夹层动脉瘤破裂，在栓塞椎动脉（包括夹层部位）后15天发生小脑出血。在这个病人中，保留的小脑后下动脉由逆行血流供血，可能在蛛网膜下腔出血的高血压和抗血小板治疗过程中受到血流动力学的压力，导致小脑出血。虽然在椎动脉栓塞的非急性期不容易发生小脑出血，但应考虑到在高血压治疗期间可能发生小脑出血。
Some complications related to vertebral artery occlusion by endovascular technique have been reported. However, cerebellar hemorrhage after vertebral artery occlusion in subacute phase is rare. In this report, we describe a patient who showed cerebellar hemorrhage during hypertensive therapy for vasospasm after embolization of a vertebral dissecting aneurysm. A 56-year-old female with a ruptured vertebral dissecting aneurysm proximal to the posterior inferior cerebellar artery developed cerebellar hemorrhage 15 days after embolization of the vertebral artery, including the dissected site. In this patient, the preserved posterior inferior cerebellar artery fed by retrograde blood flow might have been hemodynamically stressed during hypertensive and antiplatelet therapies for subarachnoid hemorrhage, resulting in cerebellar hemorrhage. Although cerebellar hemorrhage is not prone to occur in the nonacute stage of embolization of the vertebral artery, it should be taken into consideration that cerebellar hemorrhage may occur during hypertensive treatment.
