Dr Illuminati and colleagues have demonstrated that prosthetic replacement of the infrahepatic IVC after en bloc resection of leiomyosarcoma can be done safely. They had no mortality in this series of 11 patients. In addition, follow-up showed a very acceptable patency of the reconstruction as well as the absence of venous hypertension symptoms in patients with a patent graft. Interestingly, graft thrombosis was associated with the appearance of limb edema, suggesting that there was benefit from the caval reconstruction.
