The type Aii shunt is a congenital extrahepatic portosystemic shunt (ePSS) involving the left and right gastric vein and the caudal vena cava (CVC). This report describes the case of a 6-month-old Italian greyhound diagnosed with a type Aii large-diameter ePSS. Staged surgeries were employed to completely ligate the 2 gastric veins and to avoid the risk of traumatizing the shunt vessel, CVC, and celiac artery. Clinical signs improved postoperatively, and after 3 years, ultrasonography demonstrated no evidence of reoccurrence. This procedure provides an alternative surgical option for correction of ePSS type Aii. Key clinical message: This case report demonstrates congenital PSS involving the left and right gastric vein and the caudal vena could be treated with both ligation of left and right gastric vein. This technique could decrease the risk of traumatizing the shunt vessel, CVC, and celiac artery.
Aii 型分流是一种先天性肝外门体分流（ePSS），涉及左胃静脉、右胃静脉和尾腔静脉（CVC）。本报告描述了一例 6 月龄意大利格雷伊猎犬确诊为 Aii 型大口径 ePSS 的病例。采用分期手术完全结扎 2 条胃静脉，避免损伤分流血管、CVC 和腹腔动脉。术后临床症状改善，3 年后超声检查未见复发迹象。该手术为 Aii 型 ePSS 的矫正提供了一种替代的手术选择。关键临床信息：本病例报告表明，涉及左胃静脉、右胃静脉和尾腔静脉的先天性 PSS 可以通过结扎左胃静脉和右胃静脉来治疗。该技术可以降低损伤分流血管、CVC 和腹腔动脉的风险。
