A follow-up study of 30 liver transplant patients confirmed that periportal and pericaval rims of low attenuation found at CT reflect hepatic lymph stasis. The perivascular rims are found coexistent with acute allograft rejection, but are not correlated with acute rejection, immunosuppressive agents (cyclosporin A), or intercurrent infection. Disappearance of the perivascular low attenuation zone in our material coincided with normalization of liver biochemistry probably associated with reestablishment of lymphatic drainage. Like previous reports on experimental hepatic lymph stasis, our study thus indicates that lymph stasis may have harmful effects on human liver allografts.
一项对30例肝移植患者的随访研究证实，CT上发现的肝门周围和腔静脉周围低密度边缘反映了肝淋巴淤滞。血管周围边缘与急性移植物排斥反应并存，但与急性排斥反应、免疫抑制剂（环孢素A）或并发感染无关。在我们的研究材料中，血管周围低密度区的消失与肝脏生化指标的正常化相一致，这可能与淋巴引流的重建有关。与先前关于实验性肝淋巴淤滞的报道一样，我们的研究表明，淋巴淤滞可能对人肝移植产生有害影响。
