- BACKGROUND: There is a lack of agreement regarding preexisting portal vein thrombosis (PVT) in patients undergoing living donor liver transplantation (LDLT). We report the results of a single-center study to determine the impact of PVT on outcomes of adult LDLT recipients. METHODS: Of 133 cases of adult LDLT performed between January 2000 and December 2004, a thrombectomy was performed on 22 patients (16.5%) with PVT during the transplant procedure. One hundred eleven patients without PVT (group 1) were compared with those with a thrombosis confined to the portal vein (group 2; n = 15) and patients with the thrombosis beyond the portal vein (group 3; n = 7). RESULTS: The sensitivities of Doppler ultrasound and CT in detecting PVT were 50 and 63.6%. A prior history of variceal bleeding (OR = 10.6, p = 0.002) and surgical shunt surgery (OR = 28.1, p = 0.044) were found to be an independent risk factors for PVT. The rate of postoperative PVT was significantly higher in patients with PVT than in those without (18.2 vs. 2.7%; p = 0.014). In particular, the rethrombosis rate in group 3 was 28.6%. The actuarial 3-year patient survival rate in PVT patients (73.6%) was similar to that of the non-PVT patients (85.3%; p = 0.351). However, the actuarial 3-year patient survival rate in group 3 was 38.1%, which was significantly lower than that in groups 1 and 2 (p = 0.006). CONCLUSION: A thrombosis confined to the portal vein per se should not be considered a contraindication for LDLT.
