Resection of inferior vena cava leiomyosarcoma and reconstruction using ProxiCor patch

Abstract

Introduction. Leiomyosarcoma of the inferior vena cava (IVC) is a rare mesenchymal tumor originating from the endothelial smooth muscle of the intima and account for about 1–2% of all the sarcomas of the soft tissue. The objective of this article is to show a case of IVC leiomyosarcoma, it’s resection and reconstruction using a ProxiCor patch. Case outlines. We showed a case of a 65-year-old woman presented with abdominal pain and mass in subhepatic space, who underwent surgery and resection of a leiomyosarcoma of IVC. IVC was reconstructed with ProxiCor patch, and histopathologically confirmed that it was leiomyosarcoma. Conclusion. Our experience has shown that the application of extracellular matrix is safe and has given a satisfactory treatment result. A comparison with a larger patient sample should give a true representation of the advantages and disadvantages of this type of material in vascular reconstructive procedures.
