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.
