This case report describes the application of three-dimensional (3D) technologies for the surgical treatment of portosystemic shunt (PSS) with segmental caudal vena cava (CVC) aplasia. Two client-owned dogs were diagnosed with PSS along with segmental CVC aplasia using computed tomography. Through 3D volume and surface rendering, the vascular anatomic anomaly of each patient was identified in detail. A patient-specific 3D vascular model was used for preoperative planning. According to the plan established based on the 3D rendered image and printed model, shunt occlusion was performed using cellophane banding in the first case. An ameroid constrictor was used in the second case. Both patients showed good recovery without any clinical symptoms or complications. The use of 3D technologies in small animals has many advantages, and its use in vascular surgery, as in these cases, is also a therapeutic option worth considering.
本病例报告描述了三维（3D）技术在手术治疗伴有节段性尾腔静脉（CVC）发育不全的门体分流（PSS）中的应用。两只宠物犬经计算机断层扫描诊断为PSS伴节段性CVC发育不全。通过3D容积和表面渲染，详细识别了每只病犬的血管解剖异常。使用患者特异性3D血管模型进行术前规划。根据基于3D渲染图像和打印模型制定的计划，第一例病例采用玻璃纸绑扎进行分流闭塞。第二例病例使用了阿梅罗伊德缩窄器。两只病犬均恢复良好，无任何临床症状或并发症。3D技术在小动物中的应用具有诸多优势，其在血管手术中的应用，如在这些病例中，也是一个值得考虑的治疗选择。
