Understanding and recognizing anatomic anomalies of the aortic arch is important when planning extra-anatomic debranching before thoracic endovascular aortic repair. A rare anomaly is the left vertebral artery aberrantly arising from the aortic arch; found in ∼5% of adults. When present, the artery courses through the carotid sheath at a variable length before entering the third or fourth cervical transverse foramen. In the present report, we have described the case of a 49-year-old man with a symptomatic, enlarging type B aortic dissection with an aberrant left vertebral artery and the novel methods used to surgically correct his pathology.
在计划胸主动脉腔内修复术前进行解剖外血管转流术时，了解和识别主动脉弓的解剖异常非常重要。一种罕见的异常情况是左椎动脉异常发自主动脉弓；在约5%的成年人中可发现此种情况。当存在这种情况时，该动脉在进入第三或第四颈椎横突孔之前，会以不同长度走行于颈动脉鞘内。在本报告中，我们描述了一名49岁男性的病例，该患者患有有症状的、进行性增大的B型主动脉夹层，伴有异常的左椎动脉，并介绍了用于手术纠正其病变的新方法。
