Peritonitis due to rupture of retroperitoneal teratoma: computed tomography diagnosis.

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.

High-dose intra-arterial urokinase for the treatment of hepatic artery thrombosis in liver transplantation.

Two recipients of orthotopic liver transplants (OLT) underwent intra-arterial thrombolytic treatment for hepatic artery thrombosis. Complete clot lysis was achieved in both using infusion of high-dose urokinase directly into the thrombus for 12 and 3 hours, respectively. Percutaneous transluminal angioplasty (PTA) was later carried out successfully on various strictures.

Hepatic artery anastomotic stenosis after transplantation: treatment with percutaneous transluminal angioplasty.

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.
