Abstract
EARLY HEPATIC artery thrombosis (HAT) remains a major problem after pediatric liver transplantation. Often presenting in the early posttransplantation period, HAT commonly manifests as biliary complications and graft loss requiring retransplantation.1-5 Early HAT occurs within 2 weeks of liver transplantation.6 Various diagnostic modalities and treatments for HAT have been reported in the literature.1-14 The optimum diagnostic tool and treatment depends on the condition of the patient, viability of the liver, availability of specific medical expertise, and availability of organs for transplantation. Retransplantation, surgical revascularization, thrombolysis, percutaneous transluminal balloon angioplasty, or hyperbaric oxygen therapy are the therapeutic options described.14-19 The cadaveric organ shortage, especially the difficulty finding size-matched donors for pediatric recipients makes retransplantation a difficult option. Early detection of HAT and urgent revascularization are of great importance. This approach may lead to graft salvage reducing the need for retransplantation.
