Therapy options in deep sternal wound infection: Sternal plating versus muscle flap

Background and objective: Deep sternal wound infection is a feared complication of open-heart surgery. Negative pressure wound therapy has gained an important role in the treatment of deep sternal wound infection. Incisional negative pressure wound therapy has been introduced as a method to prevent wound complications after sternotomy, and lately, after flap reconstructions in the treatment of deep sternal wound infection. We aimed to study if incisional negative pressure wound therapy with PICO™ had similar beneficial effect described earlier with competing commercial devices. Methods: This study included 82 patients treated with pectoralis major muscle flap for deep sternal wound infection during the years 2006–2020. PICO group consisted of 24 patients treated with preoperative negative pressure wound therapy and postoperative incisional negative pressure wound therapy (PICO™). Two control groups included 48 patients with conventional treatment and 10 patients with preoperative negative pressure wound therapy only. Results: In the PICO group, the complication rate declined from 50.0% to 33.30%, major complication rate from 29.2% to 12.5%, and need for an additional flap from 14.6.% to 4.2% when compared to conventional treatment. The length of hospital stay decreased as well. Preoperative negative pressure wound therapy alone was associated with moderate decline in the complication rates. In addition, we described the use of split pectoralis major muscle flap reconstruction in 57 patients. To our knowledge, this is the largest published patient series describing this method in the treatment of deep sternal wound infection. Conclusions: Incisional negative pressure wound therapy with PICO™ seems beneficial after flap reconstruction. Split pectoralis major muscle flap is a versatile reconstruction option suitable to be used as a workhorse in the treatment of deep sternal wound infection.

Aims: In this retrospective study we analyzed the outcomes of flap based management in deep sternal wound infection (DSWI). Materials & Methods: Patients, who had undergone open heart surgery through median sternotomy between September 2017 and March 2020 and had developed deep sternal infections, were retrospectively analyzed in this study. Few patients found to have DSWI were managed only by Negative Pressure Wound Therapy (NPWT) and few were managed by NPWT and Bipectoral musculo fascial flap cover. The outcomes in terms of mortality and readmission in the postoperative course were obtained from the records during subsequent follow ups in OPD for six months. Results: Out of 925 patients 11 patients (1.2%) had deep sternal wound infection There were six patients (n=6, 54.55%) who received NPWT where as five patients (n=5, 45.45 %) received flap surgery following NPWT. The patient who underwent Flap surgery had a longer postoperative stay than NPWT group (46.2+/- 22.21, C.I 95%) days Vs (25.5+/- 14.41, C.I 95%) days. However, the readmission due to recurrence of infection was seen only in NPWT group (n=3, 50%) with in the period of six months following discharge. One patient out of the three readmitted patients expired due to sepsis. Conclusion: NPWT followed by bipectoral muscle flap closure has a better surgical outcome than NPW alone in deep sternal wound infection in early postoperative period
