Diffuse hepatic hemangiomas: percutaneous transcatheter embolization with detachable silicone balloons.

Two infants with severe congestive cardiac failure secondary to diffuse hepatic hemangiomas were treated by percutaneous transcatheter embolization of the hepatic arteries using detachable silicone balloons. One infant experienced dramatic improvement of the cardiac failure and showed no impairment of hepatic function. The other infant remained in a low cardiac output state following the procedure and developed acute hepatic and renal failure followed by generalized sepsis and death. Autopsy examination revealed massive hepatic hemangioendothelioma as well as areas of necrotic and viable liver parenchyma. A review of reported patients with hepatic hemangiomas treated by hepatic artery ligation or embolization showed no others who had hepatic failure. These techniques were curative in 14 of 18 patients (78%), an improvement compared with the results of other available methods of therapy.
