[Leiomyosarcoma of the inferior vena cava]

Leiomyosarcoma is a rare tumor of soft tissues. The inferior vena cava is affected infrequently, a literature review showing only 66 cases reported previously, 29 of these patients undergoing radical surgery. The case described was diagnosed during operation for gallstones, and the lesion was excised radically using an original technique. Experience of this case and opinions of various authors who have treated similar cases suggest that the factors determining choice of therapy are: the caval segment involved, an effective collateral circulation, longitudinal or circumferential extension of the affected vascular wall, the presence or absence of neoplastic or hepatic thromboses.
