Abstract Primary leiomyosarcoma of the inferior vena cava (IVC) is a rare disease, accounting for 0.5% of soft tissue sarcomas in adults [1] . A diversity of therapeutic methods have been applied to treat this type of tumor. The average survival time of patients who are not treated is merely 3-4 months [2] . The effect of radiotherapy and chemotherapy remains unclear and controversial [3] . On the other hand, the en-bloc resection with negative margins may be the only potentially curative treatment and therefore, can contribute to the long-term survival of the patients [4] . During the operation, a reconstruction graft for the defected IVC needs to be chosen [5] as the graft-related complications are the surgeons’ major concern, which include graft thrombosis and infection [6] . Growing evidence has suggested that an allogeneic vein from donation after brain death or cardiac death is a better choice to avoid these complications [7] . An allogeneic vein has been reported to be safely used in patients with pancreatic cancer in case of the portal vein and/or superior mesenteric vein invasion [8] . A cryopreserved allograft can even be applied in the management of native and prosthetic aortic infections [7] . Herein, we present a case of resection of a retrohepatic leiomyosarcoma of the IVC combined with partial caudate lobectomy and reconstruction with an allogeneic vein.
