A 7-week-old, 1.045kg female beagle dog was referred to investigate a supposed vascular ring anomaly. Cone beam computed tomography with contrast enhanced arterial phase accomplished by a rapid manual intravenous injection of iodinated agent during the scanning process revealed a persistent right aortic arch and an aberrant left subclavian artery that compressed dorsally the esophagus in the cranial mediastinum. Third left intercostal thoracotomy was performed to transect the left subclavian artery. This is the first description of a vascular ring anomaly that was diagnosed with a cone beam computed tomography in veterinary medicine.
一只7周大、体重1.045千克的雌性比格犬被转诊来调查疑似血管环异常。通过在扫描过程中快速手动静脉注射碘化剂完成的对比增强动脉期锥形束计算机断层扫描显示，存在持续的右主动脉弓和异常的左锁骨下动脉，该动脉在纵隔前部背侧压迫食管。进行了左侧第三肋间胸廓切开术以横断左锁骨下动脉。这是兽医医学中首次描述通过锥形束计算机断层扫描诊断出的血管环异常。
