Abstract

A 10-year-old neutered male domestic shorthair cat presented with acute lethargy, dysorexia, and a single episode of vomiting. Abdominal ultrasound revealed an anomalous and slightly tortuous course of the caudal vena cava (CdVC), just cranial to the junction of the renal veins. Thoracic radiographs showed an abnormally enlarged azygos vein. CT showed the absence of the prehepatic CdVC segment, with postrenal caval blood being shunted to a distended right azygos vein. Segmental CdVC aplasia should be considered in the evaluation of abdominal vascular anomalies in cats, particularly on CT angiography.

猫节段性尾腔静脉发育不全的超声、x线和CT表现。

一只10岁的绝育雄性家短毛猫表现为急性嗜睡、呼吸困难和单次呕吐。腹部超声显示尾腔静脉（CdVC）的异常和轻微弯曲的路线，只是颅到肾静脉的连接处。胸片显示奇静脉异常增大。CT显示肝前CdVC段缺失，肾后腔静脉分流至扩张的右奇静脉。在评估猫腹部血管异常时，尤其是在CT血管造影时，应考虑到节段性CdVC发育不全。
