Perforator based flaps of lateral thoracic artery (LTAP) and thoracodorsal artery (TDAP) for axillary reconstruction in patients with hidradenitis suppurativa

Hidradenitis suppurativa is a chronic inflammatory disease of apocrine gland-bearing skin, especially in the axilla. The coverage of large defects in the region of the axilla after radical resection poses a challenge to reconstructive surgery. The lateral chest offers, among others, two options for perforator flaps: the thoracodorsal artery perforator flap and the lateral thoracic artery perforator flap. This article introduces the lateral thoracic artery flap as an additional option for defect restoration alongside the thoracodorsal artery perforator flap. A total of 13 flaps (10 lateral thoracic artery perforator flaps and 3 thoracodorsal artery perforator flaps) were used for defect reconstruction in 10 patients with axillary hidradenitis suppurativa stages II or III. All patients were assessed for surgical complications pursuant to the classification of Clavien-Dindo, subjective aesthetic results, recurrence rate, and maximum abduction angle evaluated by measuring the range of motion. All flaps healed without major or partial flap necrosis. In 12 out of 13 flaps, the aesthetic result was rated very good or good.Only one patient complained of a visible scar, but rated the overall result as satisfactory. The range of motion in the shoulder was unlimited in all cases with a maximum abduction angle of 178.8 ± 4.2°. Recurrence was not observed in any case during the postsurgical follow-up of 27.2 ± 14.4 months. The use of the two perforator-based fasciocutaneous flaps of the thoraco dorsal artery and the lateral thoracic artery offers a useful and reliable option for the reconstruction of large axillary defects while maintaining full shoulder movement and providing cosmetically satisfactory results.
