Overview

  • 50-year-old female, history of gastric bypass with an initial BMI 50 and current BMI 29.
  • Five days before being seen in the clinic, she had a bilateral medial thigh lift to remove the hidradenitis and excess skin after the massive weight loss.
  • The patient has chronic iron deficiency anemia due insufficient iron absorption.

Presenting Symptoms

  • Patient’s vital signs were normal.
  • No other remarkable findings during the initial consult.

Diagnosis

  • Full-thickness necrosis of 19cm x 5cm of the right thigh dermal flap.

Treatment

  • The necrotic tissue was excised (Figure 1), and negative pressure wound therapy (NPWT) was applied for 14 days (Figure 2).
  • NPWT was discontinued after the wound bed was fully granulated. A sheet of MiroDerm, perfusion decellularized porcine hepatic-derived wound matrix, was placed (Figures 3 & 4).
  • The matrix was secured with five sutures of 3-0 poliglecaprone, a silicone adhesive dressing, and an ABD pad. Daily ABD pad changes were performed, as well as irrigation of the wound over the silicone dressing with saline solution. The patient was followed closely at the office.
  • After the initial application of MiroDerm, follow-up occurred on day 3 (Figure 5), day 10 (Figure 6), day 17 (Figure 7), day 31 (Figure 8), day 40 (Figure 9), and day 53 (Figure 10).
  • MiroDerm was fully integrated 10 days after placement. The recommendations for the patient were daily dressing changes after showering and return to work. The wound was completely healed, and follow-up concluded 8 weeks after the initial application of MiroDerm.

Summary

Necrosis of the skin is a rare complication of a medial thigh lift; it leaves a large wound defect without the option of other immediate flap rotation. MiroDerm is a hepatic-derived collagen matrix that provides exceptional rapid healing of a significant dermal defect, avoiding returning to the OR, and keeping the treatment as an outpatient.
