Unusual variation of the radial artery encountered during the elevation of radial forearm free flap

초록

Purpose: : Secondary reduction of bulky flaps is often required for cosmetic and functional improvement. Safe reduction depends on appropriate timing and extent. This study aimed to define suitable intervals, reduction amounts, and risk factors for complications. Methods: A retrospective review was performed of 30 patients who underwent flap reduction after free tissue transfer from March 2014 to April 2023. Variables included demographics, BMI, smoking history, surgical interval, extent of reduction, and complications. Results: Thirty patients (21 men, 9 women; mean age 45.9 years; mean BMI 25.5) were included, with 10 smokers. Hypertension was the most common comorbidity (n=9). Reconstruction flaps were anterolateral thigh (n=17), thoracodorsal artery perforator (n=6), latissimus dorsi (n=5), gracilis musculocutaneous (n=1), and internal pudendal with
