The development of microsurgery has most recently been focused upon the evolution of perforator flaps, with the aim of minimising donor site morbidity, and avoiding the transfer of functionally unnecessary tissues. The vascular basis of perforator flaps also facilitates radical primary thinning prior to flap transfer, when appropriate. Based upon initial clinical observations, cadaveric, and radiological studies, we describe a new, thin, perforator flap based upon the circumflex scapular artery (CSA). A perforator vessel was found to arise within 1.5cm of the CSA bifurcation (arising from the main trunk, or the descending branch). The perforator arborises into the sub-dermal vascular plexus of the dorsal scapular skin, permitting the elevation and primary thinning of a skin flap. This thin flap has been employed in a series of five clinical cases to reconstruct defects of the axilla (two cases of hidradenitis suppurativa; pedicled transfers), and upper limb (one sarcoma, one brachial to radial artery flowthrough revascularisation plus antecubital fossa reconstruction, and one hand reconstruction with a chimeric flap incorporating vascularised bone, fascia, and thin skin flaps; free tissue transfers). No intramuscular perforator dissection is required; pedicle length is 8-10cm and vessel diameter 2-4mm. There was no significant peri-operative complication or flap failure, all donor sites were closed primarily, patient satisfaction was high, and initial reconstructive aims were achieved in all cases. Surgical technique, and the vascular basis of the flap are described. The thin circumflex scapular artery perforator flap requires no intramuscular dissection yet provides high quality skin (whose characteristics can be varied by orientation of the skin paddle), and multiple chimeric options. The donor site is relatively hair-free, has favourable cosmesis and no known functional morbidity. This flap represents a promising addition to the existing range of perforator flaps.
