Adipose Tissue-preserved Skin Grafts for Lower Extremity Defects: Recommendations to Optimize Outcomes.

UNLABELLED

Adipose tissue-preserved skin grafts (ATPSGs) are full-thickness skin grafts with inclusion of a thin layer of adipose tissue. ATPSGs are recommended for reconstruction of anatomic areas that are cosmetically sensitive and for areas that functionally benefit from additional soft tissue thickness compared to traditional skin grafts. Careful intraoperative technique and postoperative care are mandatory for ATPSG success, given the expected higher metabolic demands compared to traditional grafts. A strict postoperative protocol is especially important after reconstruction of lower extremity defects.

METHODS

Detailed descriptions of intraoperative and postoperative care for ATPSG reconstructions are provided. A case is presented displaying lower extremity reconstruction with an ATPSG. The intraoperative technique includes meticulous hemostasis of the recipient site, atraumatic handling of recipient skin edges, anatomical epidermal-to-epidermal reapproximation, avoidance of tissue strangulation during inset, and careful bolster placement. The postoperative protocol after lower extremity reconstruction includes strict elevation, non-weight-bearing status, and eventual dangle protocol.

RESULTS

An 85-year-old woman was treated with an ATSG for a middle-third leg resection of squamous cell carcinoma resulting in a 9 × 5 cm defect. The strict postoperative protocol was initiated, but the patient was noncompliant with elevation and weight-bearing restrictions. She had postoperative congestion and epidermolysis that was treated with local wound care without need for additional surgery.

CONCLUSIONS

There are many benefits to ATPSG reconstruction when chosen for the appropriate candidate. The meticulous technique and strict adherence to the postoperative protocol are crucial when these reconstructions are performed. Detailed descriptions of intraoperative and postoperative recommendations to optimize outcomes after ATPSG are presented.
