Abstract:

Objective To evaluate the diagnosis and treatment of hepatic artery thrombosis（HAT）after pediatric liver transplantation. Methods From January 2012 to August 2013, there were 3 children with HAT. 1 patient experienced interventional therapy with thrombolysis, percutaneous transluminal angioplasty （PTA） and stent. 2 patients underwent emergent hepatic artery revascularization combined with intra-arterial embolectomy. The therapeutic results were monitored by clinical follow—up and imaging examination. Results 3 children developed HAT on 2, 6 and 10 days after operation, respectively. 2 children underwent emergent operation ; 1 child developed hepatic abscess and cured by puncture drainage ; another child didn't experience any complications. 1 patient who performed interventional therapy, appeared ischemic biliary complications in 3 months after operation, and was treated with basket catheter from T-tube approach and drainage tube. All children were with normal liver function, hepatic artery patency on ultrasound. Conclusions It is essential to diagnose HAT by monitoring the artery flow by Doppler ultrasound screening in the early period after operation. Interventional therapy and emergent hepatic artery revascularization are effective rescue treatments.
