A 10-year-old dog weighing 3.4 kg presented with intermittent regurgitation. Esophagography revealed that the thoracic esophagus was compressed dorsally at the region of the fourth intercostal space and segmentally dilated from the second to third intercostal region. Three-dimensional computed tomographic (CT) angiography confirmed a suspected vascular ring anomaly and also revealed multiple other vascular anomalies. These included aberrant right subclavian artery, absence of bilateral external jugular veins, right-gastric caval shunt, and a completely duplicated caudal vena cava. Findings supported the use of thoracic CT angiography to rule out additional vascular malformations in dogs with suspected vascular ring anomaly.
一只体重3.4千克的10岁犬出现间歇性反流。食管造影显示胸段食管在第四肋间间隙区域被背侧压迫，并从第二至第三肋间区域呈节段性扩张。三维计算机断层扫描（CT）血管造影证实了疑似血管环异常，还发现了其他多种血管异常。这些异常包括右锁骨下动脉异常、双侧颈外静脉缺如、右胃腔静脉分流以及完全重复的尾腔静脉。这些发现支持使用胸段CT血管造影来排除疑似血管环异常犬的其他血管畸形。
