[Thrombosis of the inferior vena caval and right atrium in amoebic abscess of the liver].

Amoebic abscess of the liver is sometimes complicated by deep venous thrombosis but extension to the right atrium is rarely observed. The authors report the case of inferior vena caval thrombosis extending to the right atrium in a case of amoebic hepatic abscess. The patient was treated initially by antibiotherapy with metronidazole associated with intravenous anticoagulation. Rapid extension of the thrombus despite this treatment led to the initiation of thrombolysis. There were no embolic complications and the outcome was good. Apart from the rarity of this complication, this case poses the problem of the management of these patients. No previous reports of the use of thrombolysis were found in the medical literature. In the light of previous publications and the present case, the authors suggest investigation by CT scanning, echocardiography and venous Doppler ultrasonography in all cases of hepatic amoebic abscess.
