Why the study?
Inferior vena cava leiomyosarcoma is a rare tumor with poor prognosis whose surgical resection remains challenging, requiring combining oncological surgery with clear margins and vascular reconstruction.
What is the optimal method of vascular reconstruction after surgical resection of inferior vena cava leiomyosarcoma?
What is the optimal method of vascular reconstruction after surgical resection of inferior vena cava leiomyosarcoma?
In the surgical management of inferior vena cava leiomyosarcoma, the reconstruction strategy should be tailored to tumor location and venous collaterality, with PTFE grafts preferred when reconstruction is necessary.
May inform individualized reconstruction decisions in IVC leiomyosarcoma surgery; leaves open need for prospective validation.
Inferior vena cava leiomyosarcoma (IVCL) is a rare tumor with a poor prognosis, and its surgical resection remains a challenge. To date, surgery is the only potentially curative treatment for IVCL with a 5-year survival rate of 55%. The main challenge is to combine oncological surgery with clear margins and vascular reconstruction of the inferior vena cava (IVC). In this review, we discuss the different approaches to vascular reconstruction after IVCL resection, using a prosthetic or autologous patch, direct suture or simple ligation without IVC reconstruction. The reconstruction of IVC depends of tumor location and its extension. We recommend no reconstruction if venous collaterality is well-established. When vascular reconstruction is required, we prefer prosthetic PTFE graft. These patients should be referred to high-volume centers with a multidisciplinary team of sarcoma surgeons with cardiothoracic, vascular and hepatic specialties.
