The supraclavicular artery island (SAI) flap has recently been repopularized through extensive use in reconstruction of head and neck defects, such as the pharynx, 1-3 parotid, 1,2 skin, 3 and esophagocutaneous fistulas. 4 The origin of the supraclavicular perforator within the anatomic posterior triangle of the neck places it in the vicinity of the cervical spine for reconstruction of posterior defects. Novel application of the SAI flap for closure of a posterior cervical spine wound with exposed hardware is described in this case report.A 52-year-old male patient with a 35 pack-year smoking history was seen by the plastic surgery service for management of a nonhealing wound in the posterior cervical spine. He was diagnosed with a right-sided Pancoast tumor (nonsmall cell carcinoma), invading adjacent osseous structures in June 2013. He underwent neoadjuvant chemoradiation (5,760 Gy cumulative dose) from July to August 2013. In September 2013, he underwent a right thoracotomy for tumor resection with cervicothoracic stabilization and posterior segmental fixation. One month postoperatively, a wound dehiscence at the cervical spine with exposed hardware was treated with a left-sided trapezius myocutaneous flap. His postoperative course was complicated by flap congestion requiring leech therapy. There was subsequent partial flap loss distally, in the proximal thoracic spine, which was closed by local tissue advancement. Two months postoperatively, native cervical spine soft tissues separated from the trapezius flap with exposed spinal hardware once again.A left-sided supraclavicular artery island (SAI) flap was performed for definitive soft tissue closure.
ResultsIn the operating room, the posterior cervical wound was debrided over the exposed hardware. A supraclavicular flap measuring approximately 6.5 cm wide by 20 cm long was designed ( ►Figs. 1 and 2). The base of the flap was in the triangle formed between the posterior border of sternocleidomastoid muscle, external jugular vein and medial clavicle. The terminal extent of the flap was over the deltoid muscle insertion. The flap was elevated in the subfascial plane until the clavicle was reached at which point the deep investing fascia was incised to liberate the flap. A tunnel was created between the donor area and cervical spine defect. The flap was deepithelialized except for a terminal 6 Â 6 cm area inset into the cervical spine defect in a tension free manner. The flap was inset 2 cm beyond the exposed hardware to avoid a suture line directly above the hardware (►Fig. 3). The flap donor site was closed primarily in layers without the need for skin grafting. Total operative time was less than 2 hours. There was no flap loss.
DiscussionThis is the first reported case of a SAI flap being used for closure of a posterior cervical spine defect. Immediate advantages of a SAI flap are its thin skin paddle, short harvest time, and preservation of regional muscle units. As with any local flap, the color of the skin island matches well with that of
