Abstract:
Objective:To explore the necessity of combined transverse upper gracilis flap and adductor magnus perforator flap in breast reconstruction.Methods:From December 2016 to February 2019, 16 female breast cancer patients, aged 27-59 years, with an average of 40.3 years, were treated in the Department of Oncoplastic Surgery, Hunan Cancer Hospital. The tumors were unilateral in 9 cases on the left side and 7 cases on the right side, with a diameter of 1.5-4.5 (2.9±0.3) cm, and all of them were stage I. Pathological diagnosis included 9 cases of invasive ductal carcinoma and 7 cases of invasive lobular carcinoma. After the modified radical mastectomy, the medial thigh perforator flap was used to reconstruct the breast. Patients were randomly divided into group A and group B. In group A, the gracilis myocutaneous flap combined with the adductor magnus perforator flap was elevated. In group B, the adductor magnus perforator flap with large size reaching the front edge of gracilis muscle was directly harvested. After all the flaps were harvested with only one major adductor perforator as vascular pedicle, ICG fluorescence imaging technology was used to verify the blood supply of the flaps.Results:Eight cases of gracilis myocutaneous flap combined with adductor magnus perforator flap and 8 cases of adductor magnus perforator flap were transplanted, The length, width and thickness of the flaps were (27.5±0.4) cm, (7.1±0.5) cm and (3.8±0.4) cm, (7.4±0.3) cm and (10.8±0.5) cm respectively. The average weight of the flap was 255 g (195 g-315 g). The mean ischemia time was 75 min (55-90 min). In 16 cases, the proximal and distal ends of internal mammary vessels were used as the recipient vessels. Only anastomosing the adductor magnus perforator vessels could ensure the reliable blood supply of the flap. All flaps survived successfully in one stage. The appearance of reconstructed breast was good and there was no obvious flap contracture and deformation. 16 cases were followed up for an average of 12.5 months, and the patients＇ self perception and appearance were satisfactory. Only hidden linear scar was left on the donor site of the medial thigh flap, and the function of hip joint and leg was not affected.Conclusions:Large size of medial thigh perforator flap pedicled with the perforator of adductor magnus can be safely and reliably cut with no needing additional harvest of gracilis muscle vascular pedicle.
