A 1-year-old female Akita dog was referred for intermittent regurgitation. Computed tomographic angiography (CTA) showed an aberrant right subclavian artery (ARSA), resulting in constriction of the esophagus. After surgical ligation of the ARSA, CTA showed that the ARSA was not enhanced by contrast medium, and that sufficient collateral circulation of the right forelimb was supplied through the vertebral artery. Furthermore, the right and left vertebral arteries merged into the basilar artery at the level of the atlas, and no abnormal expansion of the ventral spinal artery was observed. Overall, we demonstrated the importance of post-surgical CTA for identification of surgical complications, including the formation of abnormal vessel alterations.
一只1岁雌性秋田犬因间歇性反流前来就诊。计算机断层血管造影（CTA）显示右锁骨下动脉异常（ARSA），导致食管受压。对ARSA进行手术结扎后，CTA显示ARSA未被造影剂强化，右前肢有足够的侧支循环通过椎动脉供应。此外，左右椎动脉在第一颈椎水平汇入基底动脉，未观察到腹侧脊髓动脉异常扩张。总体而言，我们证明了术后CTA对于识别手术并发症（包括异常血管改变的形成）的重要性。
