Vascular ring anomalies (VRA) are relatively uncommon cardiovascular disorders in canine patients. The most common VRA is a persistent right aortic arch (PRAA) with a left ligamentum arteriosum, however various other vascular anomalies resulting in tracheoesophageal compression have also been reported. We report a case of a dog with a PRAA and left ligamentum arteriosum with a hypoplastic aberrant left subclavian artery resulting in asymmetric cervicobrachial circulation. Selective angiography and ECG-gated multi-detector computed tomography were utilized in the evaluation of these defects. The case presented represents a unique vascular anomaly of the aortic arch not previously described in veterinary medicine.
血管环异常（VRA）在犬类患者中是相对罕见的心血管疾病。最常见的VRA是伴有左动脉韧带的持久性右主动脉弓（PRAA），然而，也有其他各种导致气管食管受压的血管异常的报道。我们报告了一例患有PRAA和左动脉韧带且左锁骨下动脉发育不全导致颈臂循环不对称的犬病例。在评估这些缺陷时采用了选择性血管造影和心电图门控多探测器计算机断层扫描。该病例呈现出一种兽医医学中以前未描述过的独特的主动脉弓血管异常。
