Insights
Deep sternal wound infections (DSWIs) after cardiac surgery are complex. This case highlights successful management of chronic sternal osteomyelitis using serial debridements, antibiotics, and flap reconstruction.
Area of Science:
- Cardiovascular Surgery
- Infectious Diseases
- Plastic Surgery
Background:
- Deep sternal wound infections (DSWIs) are serious complications following cardiac surgery.
- A patient with comorbidities developed a persistent, polymicrobial DSWI leading to chronic sternal osteomyelitis.
Purpose of the Study:
- To describe the management of a complex case of chronic sternal osteomyelitis post-coronary artery bypass grafting.
- To emphasize the importance of a multidisciplinary approach and advanced reconstructive techniques for DSWI.
Main Methods:
- Serial debridements and targeted antibiotic therapy were employed.
- White cell scans were considered for assessing osteomyelitis extent.
- Reconstruction utilized a pedicled latissimus dorsi myocutaneous flap.
Main Results:
- The multidisciplinary team successfully resolved the chronic polymicrobial infection.
- The patient underwent successful closure and reconstruction with a myocutaneous flap.
- The management strategy led to a positive patient outcome.
Conclusions:
- DSWIs necessitate a prompt, multidisciplinary approach for optimal patient outcomes.
- Early plastic surgery consultation is crucial for minimizing morbidity.
- Vascularized tissue transfer is essential for reconstructing extensive DSWIs.
Abstract:
A woman in her 50s, with multiple comorbidities, underwent coronary artery bypass grafting and presented with a deep sternal wound infection (DSWI) a month later. Despite initial debridements, polymicrobial infection continued to develop and persist, leading to chronic sternal osteomyelitis which involved multiple costocartilages and the majority of her manubrium. Over a number of months, she underwent serial debridements, antibiotic treatment and investigations to manage her condition, with multidisciplinary collaboration helping resolve her infections. Successful closure and reconstruction occurred post infection resolution, involving a pedicled latissimus dorsi myocutaneous flap.DSWIs can be challenging to manage and require a timely multidisciplinary approach. Early referral to the plastics team is important for reducing patient morbidity and improving outcomes for the patient. White cell scans should be considered when available to help determine the extent of osteomyelitis in the acute surgical setting. Definitive reconstruction for extensive DSWIs requires the use of vascularised healthy tissue.
