OBJECTIVE: The objective of the present study was to analyze the incidence of portal vein thrombosis (PVT), comparing morbidity and mortality rates among those affected with and those free of this complication. In the PVT group, we also analyzed mortality related to partial (PPVT) and total (TPVT) thrombosis.
METHODS: We undertook a retrospective study of orthotopic liver transplantations from deceased donors in 617 recipients from January 1991 until October 2008. Recipients were classified according to whether they had PVT. In all cases, we considered age, sex, Model for End-stage Liver Disease score, Child-Pugh score, indication for transplantation, type of thrombosis, surgical technique blood product transfusion, and survival rate.
RESULTS: There were 48 patients with PVT (7.78%) among 670 transplantations in 617 recipients in our institution. Concerning the type of thrombosis, 28 (58.3%) were partial and 20 (41.7%) total with complete occlusion of the portal vein lumen.
CONCLUSION: PVT in liver transplant candidates is a rare event (7.8%) that entails greater difficulty in the procedure, expressed as a longer operative time, greater consumption of blood products, and complex surgical techniques. The prognosis for these patients depends on the type of thrombosis: patients with TPVT showed a higher mortality, whereas those with PPVT had survival rates comparable to those of candidates with a permeable portal vein.
