Uncommon using of the pulmonary homograft in oncological case - three years follow up

There are enough cases of colorectal cancer with liver metastasis, but inferior vena cava infiltraion with dissemination to the right atrium is an infrequent event.

This is the first case of surgical treatment of recurrent liver metastasis with the infiltration to the inferior vena cava and to the right atrium of the heart, using a cryopreserved pulmonary homograft.

The choice of a cryopreserved pulmonary homograft was preferred by the need for a radical and wide resection of tissues involved in the metastasis, as well as to potentially reduce the risk of thrombosis in the short- and long-term postoperative period.

The use of a cryopreserved homograft in operation undergoing cardiopulmonary bypass allowed us to perform the required volume of radical resection and to replace an extended section of the inferior vena cava.
