We report a case involving a ruptured acute type B aortic dissection originating from an aberrant right subclavian artery (ARSA). A thoracic stent-graft was deployed in the distal arch close to the origin of the ARSA; the entry site at the origin of the ARSA was embolized with metallic coils. Perfusion of the left subclavian artery was preserved without a surgical bypass by using a chimney graft. This procedure is a feasible and less invasive treatment for high-risk sternotomy patients and is an effective strategy for acute aortic dissections involving an ARSA.
我们报告一例源于异常右锁骨下动脉（ARSA）的急性 B 型主动脉夹层破裂病例。在远端弓部靠近 ARSA 起源处放置了一个胸主动脉支架移植物；ARSA 起源处的入口部位用金属线圈栓塞。通过使用烟囱移植物保留了左锁骨下动脉的灌注，无需进行外科旁路手术。对于高危开胸手术患者来说，该手术是一种可行且微创的治疗方法，也是治疗涉及 ARSA 的急性主动脉夹层的有效策略。
