An aberrant right subclavian artery arising distal to the origin of the left subclavian artery is the most common anomaly of the aortic arch. Degenerative diseases of aberrant subclavian arteries including aneurysms and occlusive disease have been reported previously. We believe that this case is the first reported case of fibromuscular hyperplasia affecting an aberrant subclavian artery. A 25-year-old woman admitted with a history consistent with neurogenic thoracic outlet syndrome was found to have a reduced pulse and blood pressure on the ipsilateral side caused by fibromuscular hyperplasia of an aberrant subclavian artery. A carotid-subclavian bypass via a supraclavicular incision was performed at the same time as thoracic outlet decompression. Histologic examination confirmed the presence of fibromuscular hyperplasia in the aberrant subclavian artery. This case is discussed with reference to the available literature.
起源于左锁骨下动脉起始部远端的迷走右锁骨下动脉是主动脉弓最常见的异常情况。此前已有关于迷走锁骨下动脉退行性疾病（包括动脉瘤和闭塞性疾病）的报道。我们认为，该病例是首例报道的累及迷走锁骨下动脉的纤维肌性增生病例。一名25岁女性因符合神经源性胸廓出口综合征的病史入院，检查发现其患侧脉搏减弱、血压降低，病因是迷走锁骨下动脉的纤维肌性增生。在进行胸廓出口减压的同时，通过锁骨上切口进行了颈动脉-锁骨下动脉搭桥术。组织学检查证实迷走锁骨下动脉存在纤维肌性增生。本文结合现有文献对该病例进行了讨论。
