Introduction: For patients affected by extremity or trunk soft-tissue sarcomas (STS) large resections might be needed to achieve negative margins.

The objective of this study was to evaluate the results of free-flap reconstructions (FFR) after sarcoma surgery. https://www.roneverhart.com/API-1608-II-Recording-and-Mixing-Console-p17720/
