Venous Reconstruction in Extremity Soft Tissue Sarcoma Is Not Essential

Area of Science:

• Orthopedic Oncology
• Vascular Surgery
• Limb Reconstruction

Background:

• Limb salvage is critical after extremity soft tissue sarcoma (STS) resection.
• Vascular reconstruction is a key component of successful limb salvage.
• Evaluating outcomes of vascular reconstruction in STS is essential.

Purpose of the Study:

• To assess the outcomes of vascular reconstruction in patients undergoing resection of extremity soft tissue sarcoma.
• To compare arterial and venous reconstruction methods and outcomes.
• To determine the impact of simultaneous venous reconstruction on arterial patency and complications.

Main Methods:

• Retrospective, multi-center case series of 43 patients with extremity STS.
• Review of demographics, reconstruction techniques, conduit types, complications, graft patency, limb salvage, and survival.
• Analysis of data from March 2005 to December 2020 at two Korean centers.

Main Results:

• Higher primary patency for arterial (82.5%) versus venous (56.3%) reconstructions at 12 months (P < .001).
• Autologous saphenous veins were the most common conduit (56.2%).
• No significant difference in arterial patency or complications with or without simultaneous venous reconstruction; limb salvage and survival rates were high.

Conclusions:

• Venous reconstructions had poorer patency rates compared to arterial reconstructions.
• Simultaneous venous reconstruction may not be essential for arterial patency or complication rates in STS.
• Further research is warranted to fully evaluate the role of simultaneous venous reconstruction.
