INTRODUCTION: Portal venous thrombosis (PVT) is common in patients with liver cirrhosis, undergoing liver transplantation (LT); in our setting, this is the first publication with an emphasis on results and surgical strategies. OBJECTIVE: Was to review the case history of the Guillermo Almenara Irigoyen National Hospital, determine characteristics, types of PVT and surgical management. MATERIALS AND METHODS: We analyzed patients undergoing LT who presented PVT between March 2000 and Jun 2018. Of 255 liver transplants in 239 patients, 229 adults and 26 pediatric, these last were excluded. RESULTS: We found 27 patients had PVT (12.2%) diagnosed in pre and during LT, none with malignant PVT, the most frequent etiologies of cirrhosis were non-alcoholic steatohepatitis (37.4%), alcoholic steatohepatitis (22%), autoimmune hepatitis (AIH) (11%), virus B hepatitis (VBH) (7.4%) and others (11.5%). According to PVT grade: Yerdel I in ten patients (37%), Yerdel II in te patients (37%), Yerdel III in four patients (15%) and Yerdel IV in three patients (11%). Surgical strategy used: thrombectomy in 23 cases (85.2%), hemitransposition cavoportal in 2 cases (7.4%), reno-porto anastomosis with interposition of venous graft in 1 case (3.7%) and thrombectomy with interposition of venous graft in 1 case (3.7%). The re - PVT was present in two cases (7.5%). The PVT decreased patient survival after LT 1 year (81.2%), 3 years (78.4%) and 5 years (78.4%) compared with patients without PVT 1 year (84.6%) 3 years (82.3%) and 5 years (82.3%) respectively. CONCLUSIONS: Cirrhosis with PVT was clinically more unbalanced, survival decreased to a higher degree of PVT. Surgical behavior similar to other transplant centers. Early diagnosis is essential to take early surgical action and decrease morbidity and mortality after LT.
