Two orthotopic liver transplant recipients underwent percutaneous transluminal angioplasty (PTA) for stricture of the hepatic arterial anastomosis. In both, arterial revascularization was effected by end-to-end anastomosis between the donor common hepatic artery and the recipient's hepatic artery. Both patients had elevated liver enzyme levels, abnormal results on duplex Doppler images, and severe stricture on angiograms. In one patient, percutaneous biopsy revealed graft ischemia. PTA was performed successfully without complications. PTA produced substantial improvement in biochemical, duplex Doppler, histologic, and angiographic patterns. Both patients were asymptomatic 5 and 6 months after PTA.
