Early and aggressive surgical debridement and negative pressure wound therapy to treat necrotizing fasciitis in three dogs.

OBJECTIVE

To report the management and outcomes of dogs with necrotizing fasciitis (NF) treated with early, aggressive surgical debridement and negative pressure wound therapy (NPWT).

STUDY

DESIGN

Short case series.

ANIMALS: Three dogs surgically treated for NF.

METHODS

Clinical signs in the three dogs included an identified wound, severe pain, fever, and progressive erythema. A tentative diagnosis of NF was based on the presence of suppurative inflammation and intracellular bacteria seen in fine needle aspirates and clinical progression in each case. Each dog was treated with surgical debridement within 6 hours of clinical suspicion for NF. Necrosis affected multiple tissue layers was noted surgical exploration. Systemic supportive care and antibiotherapy were also provided for 3 to 4 weeks postoperatively.

RESULTS

Three surgical debridements were required in two dogs, and four surgical debridements were required in one dog. All of the surgical sites were managed with NPWT until final primary closure was possible at 4, 5, and 6 days after initial surgery. Results of histopathology and culture of the surgical sites were consistent with NF as described in each case. All dogs survived to discharge and long-term follow up.

CONCLUSION

Management with early surgery, multiple debridements, and the use of NPWT led to resolution of NF in three dogs.
