Superior epigastric artery perforator flap for reconstruction of deep sternal wound infection.

BACKGROUND

The treatment of deep wound sternal infection requires loco-regional pedicled flaps, usually with muscular flaps. Perforator propeller flaps represent the ultimate progress in the history of reconstructive surgery. We report here our experience with the superior epigastric artery perforator (SEAP) flaps to repair sternal defect.

PATIENTS AND

METHODS

Six patients presenting deep sternal wounds infection were treated with SEAP propeller flap, between March 2015 and June 2017. The mean age was 71.5 (range 53-83) years. The mean length and width of the defect were 16.2 × 7 cm (ranging 8-20 × 4-10). An elliptical skin flap pedicled on the SEAP was harvested in the inframammary fold and rotated up to 90° to cover the defect.

RESULTS

All SEAP flaps achieved a successful entire coverage of the defect. The mean size of the skin paddle of the flap was 20.2 × 7.3 cm (ranging 14-27 × 6-9). All flaps were able to provide a complete sternal wound cover. Venous congestion was present in five cases and adequately treated by leech therapy; necrosis was distal in one case, and interesting the entire superficial flap in two cases but with deep tissues remaining viable and able to cover the mediastinum: an infected flap required revision. Satisfyingly, at 2-years postoperative follow-up all-patients were alive with a successful mediastinal cover.

CONCLUSIONS

The SEAP Perforator propeller flap is an alternative to muscle flaps to achieve treatment of deep and large sternal wound infection.
