We aimed to demonstrate the feasibility of thoracic endovascular aortic repair for type B aortic dissection in patients with an insufficient proximal anchoring area due to the vertebral artery originating from the aortic arch.
In this study, we report two patients with type B aortic dissection who were complicated with left vertebral artery course variation. Specifically, the left vertebral artery originated from the aortic arch. In these patients, the anchoring area (<15 mm) was not sufficient between the left vertebral artery and the ruptured aortic dissection.
We reconstructed the left vertebral artery during horacic endovascular aortic repair. Both patients recovered well and were discharged without any adverse events.
Our experience shows that horacic endovascular aortic repair is feasible in patients with type B aortic dissection who have an insufficient proximal anchoring area due to the left vertebral artery originating from the aortic arch.
我们旨在证明对于因椎动脉发自主动脉弓而近端锚定区不足的 B 型主动脉夹层患者，行胸主动脉腔内修复术的可行性。
本研究报告了 2 例 B 型主动脉夹层患者，其左椎动脉走行变异，具体表现为左椎动脉发自主动脉弓。在这些患者中，左椎动脉与破裂的主动脉夹层之间的锚定区（<15mm）不足。
我们在胸主动脉腔内修复术中重建了左椎动脉。两名患者均恢复良好，无任何不良事件出院。
我们的经验表明，对于因左椎动脉发自主动脉弓而近端锚定区不足的 B 型主动脉夹层患者，行胸主动脉腔内修复术是可行的。
