Extremity reconstruction with superficial circumflex iliac artery perforator free flap: Refinements and innovations after 101 cases.

ABSTRACT

INTRODUCTION: The superficial circumflex iliac artery perforator flap is based on perforators originated on the superficial circumflex iliac artery. This flap is thin and pliable, of moderate size, and has a concealed donor site. The authors report their experience, innovations, and refinements in both planning and execution, and the outcomes obtained after 101 extremity reconstruction consecutive cases. PATIENTS AND METHODS: A total of 101 superficial circumflex iliac artery perforator flaps were prospectively reviewed and followed up for at least one year at Hospital del Trabajador. The flaps were used for both upper (n = 21) and lower limbs (n = 80), planned with computed tomography angiography/augmented reality, and raised above the superficial fascia using a standardized approach. Demographic data, anatomy of the flap, surgical technique, and the results were assessed. RESULTS: Average flap size was 90.5 cm2, ranging from 25 to 212 cm2. Total flap loss occurred in 6 flaps (5.9%). Four patients developed complications at the donor site. Debulking surgery was performed in 7 patients (6.9%). The average follow-up period was 850 days (range, 370-1405 days). CONCLUSIONS: The superficial circumflex iliac artery perforator flap is versatile, thin, and pliable, suitable for covering even large defects in either the upper or lower extremities, obtaining a shallow contour and optimal esthetics results. The elevation can be standardized, but requires training and proper planning. This is the largest series in a Western country reporting the experience, refinements, and innovation that allows for better results in limb reconstruction.
