Objectives: Portal vein (PV) reconstruction is a crucial factor for successful living donor liver transplantation (LDLT). Portal vein thrombosis (PVT) remains a critical problem in LDLT because of technical demands and sufficient venous graft harvesting. This study aimed to describe in detail of PV reconstruction and outcomes of patients with PVT.
Methods: We performed adult-to-adult LDLT for 123 patients between March 2002 and December 2016. Thirteen patients (10.6%) had PVT at the time of LDLT, which were classified as grade I in 2 patients, grade II in 4 patients, grade III in 6 patients and grade IV in 1 patient, according to Yerdel's classification. We retrospectively analyzed the surgical technique and postoperative complications of PV reconstruction for patients with PVT, and compared to patients without PVT.
Results: Surgical treatments for 13 patients with PVT were as follows: thrombectomy alone in 2 patients, replaced interpositional venous grafts in 8 patients: 3 using internal jugular vein (IJV) and 5 using external iliac vein (EIV), mesoportal jump grafts in 2 patients: 1 using IJV and 1 using IJV+EIV, and renoportal anastomosis using external iliac venous graft in 1 patient. Among 8 patients with interpositional venous grafts, 5 venous grafts (IJV: 2, EIV: 3) were passed dorsal side of the pancreas without using jump graft. The postoperative complication associated with PV anastomosis of patients with PVT occurred in 1 of 13 (7.7%) patients, who developed anastomosis bleeding caused by coagulation disorders at POD27. On the other hand, 1 of 110 (0.9%) patients without PVT also developed same postoperative PV complication at POD2. Post-transplant survival rates at 1 and 5 years were not statistically differences between patients with and without PVT (1 year; 84.6% vs. 79.1%, 5 years; 53.8% vs. 65.8%, p=0.332).
Conclusion: The outcomes of PV reconstruction in the patients with PVT by suitable surgical techniques using venous grafts are satisfactory, being comparable to those of patients without PVT in adult-to-adult LDLT.
