Abstract:
Objective To evaluate the types and imaging features of early and late complications after liver transplantation.Methods A retro-spective analysis was conducted on the complications imaging data from 124 patients after liver transplantation.The CT and MRI characteristics of these complications was analyzed,categorized based on their occurrence time and type.Results The postoperative complications in the total 124 patients included vascular complication in 85 patients,biliary complication in 78 patients,and parenchy-mal complication in 21 patients.Additionally,the simple and complex complications were exhibited in 43 and 81 patients.Early vas-cular complication accounted for 69.8％,especially 21 cases(91.3％)were with early hepatic artery thrombosis.Bile leakage in 9 cases occurred in the early postoperative period,whereas biliary stenosis in 43 cases and biliary stones in 23 cases were observed in the late postoperative period.All ischemic infarction in 13 cases occurred in the early postoperative period.Among the 10 cases of liver abscess,8 cases were secondary to ischemic necrosis of liver parenchyma,and other 2 cases were secondary to suppurative cholangitis.Addi-tionally,6 cases of liver tumor recurrence were all detected in the late postoperative period.Conclusion The types of complications occurring after liver transplantation vary over time,and CT and MRI can be used to detect and evaluate postoperative complications.
