Description
Surgeons rebuilding a lower leg with a parascapular flap must be sure the far end of the tissue gets enough blood. Leonard Knoedler and co-authors review 112 such operations from 2015 to 2024. In forty-five cases, the team checked blood flow during surgery with a glowing dye seen under near-infrared light; the rest were judged by eye and touch alone.
The dye view exposed weak flow in a third of its cases, and those trimmed flaps all healed cleanly. Partial tissue death hit about seven percent of the dye group against eighteen percent of controls. Reoperations also ran lower with the dye. The 2026 study backs the scan as a strong guide during surgery.
