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.

Retroperitoneal benign cystic teratoma is relatively rare in adults. We report a case of traumatic rupture of primary retroperitoneal teratoma into peritoneum that produced chemical peritonitis. It was demonstrated by computed tomography, which showed fat-fluid levels in the peritoneum. We suggest that the demonstration of fat-fluid levels in the peritoneum could be a reliable sign of intraperitoneal rupture of abdominal teratoma and subsequent chemical peritonitis.
