Early postoperative CT scans of three patients who had undergone liver transplantation show hypodense areas surrounding the portal venous system and to a lesser extent the intrahepatic inferior vena cava. These changes were considered to represent dilated lymphatic vessels caused by impaired lymphatic drainage of the transplant after total interruption of the lymphatic vessels at surgery. This hypothesis was tested in three piglets after complete surgical interruption of the lymphatic vessels of the liver. Results of histologic examinations and an additional long-term follow-up CT study in one patient suggest that hypodense periportal and pericaval areas are a reversible CT finding in liver transplants caused by lymph stasis.
三名接受肝移植患者的术后早期CT扫描显示，门静脉系统周围出现低密度区域，肝内下腔静脉周围也有较小范围的低密度区域。这些变化被认为是由于手术中淋巴管完全中断后，移植肝的淋巴引流受损导致淋巴管扩张所致。在三只仔猪身上进行了手术完全中断肝脏淋巴管的实验，以验证这一假设。一名患者的组织学检查结果以及额外的长期随访CT研究表明，门静脉周围和腔静脉周围的低密度区域是肝移植中由淋巴淤滞引起的一种可逆性CT表现。
