Aortic dissection is the most common and the most lethal event that can involve the aorta. Typically, aortic dissection presents with sharp, tearing, or ripping pain. Alternatively, the patients may suffer from possible extension of the dissecting aneurysm into the supra-aortic vessels resulting in syncope in 9.4 % of patients cerebrovascular accidents in 4.7 %. We present a case of recurrent aortic dissection, which presented with recurrent transient ischemic attacks (TIAs). The etiology of the neurological symptoms was attributed to a steal phenomenon. The right subclavian artery was supplied by retrograde flow from the right internal carotid artery through the false lumen of the dissection. To prevent further hemodynamic TIAs, we successfully occluded the proximal part of the false lumen of the dissection responsible for the steal phenomenon.
主动脉夹层是最常见和最致命的可以累及主动脉的事件。通常，主动脉夹层表现为剧烈的、撕裂样或撕裂样疼痛。或者，患者可能会因夹层动脉瘤向升主动脉扩展而导致晕厥，发生率为 9.4%，脑血管意外发生率为 4.7%。我们报告了一例复发性主动脉夹层，其表现为复发性短暂性脑缺血发作（TIA）。神经系统症状的病因归因于盗血现象。右锁骨下动脉由逆行血流从右颈内动脉通过夹层的假腔供应。为了防止进一步的血流动力学 TIA，我们成功地闭塞了负责盗血现象的夹层假腔的近端部分。
