Non-recurrent inferior laryngeal nerve (NRILN) is a rare embryologic anomaly that can increase the risk of injury during thyroid surgery. Although the association between the NRILN and an aberrant right subclavian artery has been reported, to date there have been no reports describing cases of NRILN with multiple vascular abnormalities. A 60-year-old man with papillary thyroid carcinoma and a history of right internal carotid artery occlusion by thrombosis was examined with magnetic resonance angiography (MRA). The right NRILN was found during a total thyroidectomy with surrounding lymph node dissection. MRA revealed an aberrant right subclavian artery and aplasia of the bilateral posterior communicating arteries composing the circle of Willis. This is the first clinical report demonstrating NRILN with multiple vascular abnormalities. Patients with NRILN must be examined for vascular anomalies and associated lesions such as aneurysms and thromboembolism.
非复发性喉返神经（NRILN）是一种罕见的胚胎学异常，可增加甲状腺手术期间的损伤风险。尽管已有报道称NRILN与异常右锁骨下动脉之间存在关联，但迄今为止，尚无关于伴有多种血管异常的NRILN病例的报道。一名60岁的男性，患有甲状腺乳头状癌且有右颈内动脉血栓形成闭塞史，接受了磁共振血管造影（MRA）检查。在全甲状腺切除术及周围淋巴结清扫术中发现了右侧NRILN。MRA显示存在异常右锁骨下动脉以及构成Willis环的双侧后交通动脉发育不全。这是第一份展示伴有多种血管异常的NRILN的临床报告。必须对患有NRILN的患者进行血管异常以及诸如动脉瘤和血栓栓塞等相关病变的检查。
