Abstract:
Retrohepatic inferior vena cava (RIVC) begins at the base of renal vein and ends at the right atrium. Left, middle, right hepatic vein, inferior right hepatic vein etc. run into it. The major part of RIVC is wrapped in the caudate lobe of liver. It is adjacent to the abdominal trunk and vertebral body, having important anatomical significance. Inferior vena cava tumor thrombus includes two types. One is tumor thrombus formations in the RIVC. The other is direct invasion of tumor into RIVC wall. These two types correspond to different surgical treatment methods. The cancer thrombus in the vena cava can be treated by thrombus removal, while the tumor invading the vena cava wall requires resection of the invaded vascular wall and vascular reconstruction. Regardless of the types, improper surgical treatment is easy to cause injury and bleeding, leading to severe consequences. In this article, the main points of surgical management of different types of cancer thrombus in RIVC are introduced, providing methods to handle them.
