Abstract
Background: Retrohepatic inferior vena cava (RIVC) resection without reconstruction in ex vivo liver resection and autotransplantation (ERAT) for advanced alveolar echinococcosis (HAE) is unclear. Methods: Depending on the presence of a rich collateral circulation and stable blood volume in ERAT, we chose not to rebuild the RIVC. Then, we chose an appropriate revascularization technique for the hepatic and renal veins. Finally, all ERAT procedures were completed, and short- and long-term outcomes were observed. Results: Between February 2014 and August 2018, 5 advanced HAE patients who underwent ERAT required the described technique. One patient died of circulatory failure 1 day after surgery. Another four patients, with a median follow-up duration of 18 months (range, 10-25 months), demonstrated normal liver and kidney function, no thrombosis and no HAE recurrence. Conclusions: Through the long-term results of ERAT, the pros and cons of not reconstructing the RIVC need to be re-examined. In cases with a rich collateral circulation, the RIVC can be reconstructed. However, in cases requiring the resection of multiple organs, RIVC reconstruction is prudential.
