Could Periodic Laser Doppler Imaging Monitoring Enhance Insights Into Perfusion Challenges in Anterolateral Thigh Flaps? A 5-Year Retrospective Analysis.

Background: Postoperative monitoring after free flap transfer is challenging, and clinical observation alone remains subjective and unquantifiable. Furthermore, re-explored flaps often have a poor appearance, making it challenging for surgeons to decide whether further aggressive treatments are necessary. Laser Doppler (LD) imaging can provide noninvasive, real-time, and quantifiable monitoring for flap perfusion.
