Different reconstruction methods of inferior vena cava in the ex-vivo liver resection and auto-transplantation for hepatic alveolar echinococcosis / 中华器官移植杂志

ABSTRACT

Objective:To explore the application of different reconstruction methods of retrohepatic inferior vena cava (RHIVC) in the ex-vivo liver resection and auto-transplantation(ELRA)for hepatic alveolar echinococcosis (AE).Methods:The 88 patients with end-stage hepatic AE treated by ELRA from August 2010 to December 2018 were divided into 3 groups according to the different methods of RHIVC reconstruction, respectively , group A, autologous vascular repair and reconstruction group (n=50); group B, RHIVC replacement group (n=31); group C, RHIVC resection without reconstruction group (n=7), and the clinical data were analyzed and followed up.Results:The average operation time of group A, B and C was 16.32±3.20 h, 15.99±3.32 h, 16.86±4.18 h ( P>0.05), The average anhepatic phase was398.48±104.12 min, 389.41±135.25 min, 337.43±108.65 min( P>0.05), The differences were not statistically significant. The average hospital stays after surgery in the three groups were 30.64±18.54 d, 25.94±16.37 d, 51.29±29.43 d ( P<0.05), There were significant statistical differences, and the results showed that the group B was significantly less than other two groups. The incidence of IVC related complications in group A and B was 20.0% and 9.7%. Among all the subjects, RHIVC stenosis was found in 9 patients and thrombus was formed in 4 patients in postoperative. Conclusions:RHIVC reconstruction methods can be selected appropriately according to the defect degree of lumen after resection.
