The successful use of low-dose recombinant tissue plasminogen activator for treatment of intracardiac/pulmonary thrombosis during liver transplantation.

Intracardiac thrombosis and pulmonary embolism are uncommon complications during liver transplantation but carry a high mortality rate. We report the successful use of low-dose recombinant tissue plasminogen activator (0.5-4 mg) administration in 4 patients. Early diagnosis through transesophageal echocardiography and pulmonary artery catheterization may have contributed to the rapid thrombolysis.
