To retrospectively evaluate the long-term outcomes of percutaneous transhepatic balloon angioplasty for portal vein stenosis after pediatric living donor liver transplantation.

Between October 1997 and December 2013, 43 patients (19 boys, 24 girls; mean age, 4.1 years) who had undergone living donor liver transplantation were confirmed to have portal vein stenosis at direct portography with or without manometry, and underwent percutaneous interventions, including balloon angioplasty with or without stent placement. Technical success, patency rates and major complications were evaluated. Follow-up periods after the initial balloon angioplasty ranged from 5 months to 169 months (mean, 119 months).

Technical success was achieved in 65 of 66 sessions (98.5%) and in 42 of 43 patients (97.7%). At 1, 3, 5, and 10 years after the first percutaneous transhepatic balloon angioplasty, the rates of primary patency were 83%, 78%, 76% and 70%, respectively, and the rates of primary-assisted patency were 100%, 100%, 100% and 96%, respectively. In major complication, severe asthma attack and portal vein thrombosis subsequent to balloon angioplasty were noted.

Percutaneous transhepatic balloon angioplasty for portal vein stenosis after pediatric living donor liver transplantation was safe and effective.

Percutaneous transhepatic balloon angioplasty might be a safe and effective treatment for portal vein stenosis after pediatric living donor liver transplantation.
