一个九个月大的去势雄性家短毛猫，有三个月的血尿病史。怀疑门体分流和膀胱内结石，并进行计算机断层扫描血管造影。计算机断层血管造影发现肝外门体分流和部分异常肺静脉连接，右尾叶的叶静脉流入尾腔静脉。对猫进行麻醉后，观察到呼吸急促和喘息性呼吸音，胸部X线摄影显示右肺中叶肺不张和左颅叶非结构化间质模式。超声心动图显示左、右心房扩大，室间隔轻度扁平。基于这些发现，怀疑心源性肺水肿，并给予猫呋塞米治疗。第二天临床症状消失。在第47天和第157天关闭肝外门体分流。术后左房扩大和室间隔变平减弱。在撰写本报告时（诊断后17个月），猫未表现出临床体征，但主观右心房增大仍处于大致相同的水平。本报告是第一例部分肺静脉异常连接和门体分流的猫。
A nine-month-old castrated male domestic shorthair presented for evaluation with a three-month history of hematuria. Portosystemic shunts and calculi within the bladder were suspected, and computed tomography angiography was performed. Computed tomography angiography identified an extrahepatic portosystemic shunt and a partial anomalous pulmonary venous connection, with the lobar vein of the right caudal lobe draining into the caudal vena cava. After anesthesia was administered to the cat, tachypnea and wheezing respiratory sounds were observed, and thoracic radiography revealed the right middle lung lobe atelectasis and an unstructured interstitial pattern in the left cranial lobe. Echocardiography showed left and right atrial enlargement and slight interventricular septal flattening in diastole. Based on these findings, cardiogenic pulmonary edema was suspected, and the cat was treated with furosemide. The clinical symptoms were resolved the next day. Closure of the extrahepatic portosystemic shunt was performed on days 47 and 157. Left atrial enlargement and interventricular septal flattening were attenuated after the procedure. At the time of writing this report (seventeen months after diagnosis), the cat exhibited no clinical signs, but subjective right atrial enlargement remained at approximately the same level. This report represents the first case of a partial anomalous pulmonary venous connection and a portosystemic shunt in a cat.
