Abstract
PURPOSE: Evaluation of the efficacy and safety of percutaneous treatment of vascular stenoses and occlusions in pediatric liver transplant recipients. METHODS: Fifteen children (mean age 8.3 years) underwent interventional procedures for 18 vascular complications after liver transplantation. Patients had stenoses or occlusions of portal veins (n = 8), hepatic veins (n = 3), inferior vena cava (IVC; n = 2) or hepatic arteries (n = 5). Technical and clinical success rates were evaluated. RESULTS: Stent angioplasty was performed in seven cases (portal vein, hepatic artery and IVC), and sole balloon angioplasty was performed in eight cases. One child underwent thrombolysis (hepatic artery). Clinical and technical success was achieved in 14 of 18 cases of vascular stenoses or occlusions (mean follow-up 710 days). CONCLUSION: Pediatric interventional radiology allows effective and safe treatment of vascular stenoses after pediatric liver transplantation (PLT). Individualized treatment with special concepts for each pediatric patient is necessary. The variety, the characteristics, and the individuality of interventional management of all kinds of possible vascular stenoses or occlusions after PLT are shown.
