Аннотация
BACKGROUND: Abdominal flap-based breast reconstruction is challenging in the overweight and obese population not only because of increased donor-site complications, but also because excessive flap thickness makes inset cumbersome, requiring thinning and remodeling that frequently result in aesthetically poor outcomes.
METHODS: The authors started by studying 10 deep inferior epigastric artery perforator flaps with angiographic computed tomography. Then, they prospectively performed 21 breast reconstructions using a superficial thinning technique reliant on a constant suprafascial vessel as the pedicle for the remaining deep fat and compared the rate of complications with their previous experience using traditional flap thinning techniques.
RESULTS: All samples studied showed a suprafascial division of the main perforator. Two constant branches were identified, one coursing over the Scarpa fascia and displaying a robust network of linking vessels with the subcutaneous and subdermal plexuses. That anatomical insight was used to develop a flap-thinning technique tested on 21 consecutive high-body mass index patients. A 7-year retrospective analysis (n = 164) showed no significant correlation between body mass index and incidence of complications except for a long-term upper pole step deformity that was associated with increasing body mass index (p = 0.001). No statistically significant difference in complications was found comparing high-body mass index patients from the retrospective group (n = 72) with the superficial thinning group, but a highly suggestive difference (p = 0.061) was found regarding the avoidance of the step deformity using the superficial thinning technique.
CONCLUSION: The presence of a constant suprafascial perforator branch makes superficial DIEP thinning a safe technique that facilitates inset and improves the reconstructed breast contour of obese patients.
CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
