Revisiting the pedicled circumflex scapular artery (pCSA) perforator flap: From simple to complex locoregional reconstructions

Background: Soft tissue defects involving the axilla and the upper back region are often complex to treat. The complexity of these defects may be extremely different, ranging from superficial skin damage to large loss of substance with lymphatic drainage impairment. The pedicled circumflex scapular artery (pCSA) perforator flap represents a valid procedure in this setting. It can be tailored according to the patient's needs, and its intraseptal pedicle allows a quick dissection with a wide range of motion. Patients and methods: Twenty-four consecutive patients treated by means of pCSA perforator flap were included. All the flaps were pedicled and were used for locoregional reconstructions. The etiology of the defects was an oncologic resection in 15 cases, acne/hidradenitis suppurativa resection in 6 cases, lymphatic complication in 2 cases, and burn in 1 case. Patients' mean age was 61 years old; seventeen were males and seven were females. Results: All the patients were successfully treated with good aesthetic and functional results. One patient presented with a wound dehiscence, which required secondary surgical treatment. No partial or complete flap losses were encountered. Primary closure of the donor site was achieved in all cases. The mean follow-up period was 10.5 months (range 6-12). Conclusions: This case series shows the reliability and versatility of the pCSA perforator flap for locoregional reconstructions. Because of its rich vascularisation, extensive or unconventionallyshaped flaps are possible. Moreover, its lymphatic rich tissues make it suitable for the treatment of complications related to axillary lymphadenectomy.
