肝移植术后并发症的CT和MRI诊断

目的:分析肝移植术后各种并发症的CT、MRI表现,评价CT、MRI在肝移植术后并发症中的诊断价值。方法:回顾性分析24例肝移植术后发生并发症的患者的CT、MRI资料,全部病例并发症均经手术、肝组织活检或血管、胆道造影证实。结果:24例患者CT、MRI诊断门脉主干吻合口狭窄4例;肝动脉狭窄3例;下腔静脉吻合口狭窄1例;胆管吻合口狭窄4例;肝门水平非吻合口狭窄5例;移植排异反应4例,肝癌复发7例。结论:CT、MRI能发现大部分肝移植术后并发症,是诊断肝移植术后并发症的有效方法。

CT and MRI Diagnosis of Complications after Liver Transplantation

Objective:To study the CT and MRI findings of complications following liver transplantation.Methods:The CT and MRI appearances in twenty-eight patients with complications after liver transplantation,which were confirmed by surgery,liver biospy,or angiography/cholangiography,were analyzed retrospectively.Results:Of these 24 patients,there were stenosis of main trunk of portal vein anastomosis(n=4),stenosis of hepatic arterial anastomosis(n=3),stenosis of inferior vena cava anastomosis(n=1),stenosis of bile duct anastomosis(n=3),non-anastomotic stenosis of bile ducts at the portal region(n=4),transplant rejection(n=4),hepatic carcinoma recurrence(n=7).Conclusions:CT and MRI can demonstrate most of the complications and are valuable in the diagnosis of complications after liver transplantation.
