Diagnostic Value Of CTA For Second Hepatic Hiulm Of End-stage Hepatic Alveolar Echinococcosis Before Autotransplantation

Objective: To investigate the efficiency of CTA in evaluating vascular invasion of the second hepatic hilum in patients with end-stage alveolar echinococcosis before auto liver transplantation.Methods: From June 2008 to August 2017,97 patients who were pathologically confirmed as HAE,and underwent auto liver transplantation in the first affiliated Hospital of Xinjiang Medical University were retrospectively analyzed.All of them were examined by CTA.The intraoperative pathological results were used as the gold standard to analyze the diagnostic efficacy of CTA in the diagnosis of vascular invasion of the second hepatic hilum.Results: In 97 cases,there were 8 branches of left hepatic vein,5 branches of middle hepatic vein,6 branches of right hepatic vein,4branches of retrohepatic inferior vena cava,16 branches of left and middle hepatic veins,19 branches of right and middle hepatic veins,1 branch of right hepatic vein and retrohepatic inferior vena cava,and 38 branches of three hepatic veins and retrohepatic inferior vena cava were invaded by the alveolar echinococcosis lesion.Compared with the results of operation,the coincidence rate of single vessel invasion was 84.62%,and that of multiple vessel invasion was 63.51%.The total coincidence rate was 69%.The difference was statistically significant.Conclusion: CTA in patients with end-stage alveolar echinococcosis before auto liver transplantation can accurately grasp vascular invasion,contribute to the selection of surgical methods,and provide reliable imaging information for objective evaluation before operation.it is suggested that it should be widely used.
