Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Methods: This single-center retrospective cohort study included some patients with grade III/IV PVT who underwent LT and were divided into two periods: in both periods, patients underwent modified eversion thrombectomy. However, in Period 1 (2016-2019), nonanatomical anastomosis was performed if portal flow was insufficient, and in Period 2 (2019-2024), patients with persistent hypoperfusion underwent additional LTH-based EVT (stenting or shunt occlusion). Perioperative outcomes (operative time, anhepatic phase, and anastomosis type) and long-term outcomes (graft survival and complication rates) were compared between groups.
