Portal vein thrombosis(PVT) after deceased donation has been widely described as a liver transplant complication that can lead to graft failure, high morbidity and mortality. Little data is available regarding to risk factors, classification and treatment of PVT after LDLT.
Methods
Retrospective analysis of 421 adult-to-adult LDLTs performed between January-2004 and November-2014. Perioperative characteristics and outcomes of patients with a new PVT after LDLT(n=28) were compared with those without PVT (n=393).
Results:
Twenty-eight patients had a new PVT(t-PVT). Ten cases were classified as early-PVT(e-PVT) occurring within 1 month after LDLT, and 18 cases as late-PVT(l-PVT) appearing later than 1month. Multivariate analysis from perioperative variables showed that splenectomy(t-PVT: p=0.001; e-PVT: p=0.012; l-PVT: p=0.035) and donor age(l-PVT: p=0.010) were significant risk factors for PVT. Salvage rate for treatment in e-PVT and l-PVT was 100% and 50%, respectively, without early event of re-thrombosis. Mortality within 30days was similar (No-PVT: 2% vs e-PVT: 10%, p=0.155). No significant difference in the 1-(92% vs 89%), 5-(82% vs 79%) and 10-(79% vs 68%) years graft survival between the No-PVT and t-PVT groups (p= 0.246). No retransplantion was neccesary as consequence of PVT. The 1-(96% vs 89%), 5-(86% vs 82%) and 10-(83% vs 79%) years patient survival was similar for the patients without PVT and the t-PVT group (p=0.706)
Conclusion
Early diagnosis and management of PVT after LDLT can lead to acceptable early and long-term results without affecting patient and graft survival.
