[Showing no increase of C-reactive protein and developing non-bacterial median chest wound dehiscence after coronary...

Area of Science:

• Cardiovascular Surgery
• Wound Healing
• Inflammation Markers

Background:

• Coronary artery bypass grafting (CABG) is a common surgical procedure for treating three-vessel disease.
• Post-operative inflammation, often monitored by C-reactive protein (CRP), typically resolves within weeks.
• Chest wound complications can impact patient recovery and quality of life.

Observation:

• A 72-year-old male patient developed progressive median chest wound dehiscence 40 days post-CABG.
• Bacterial cultures of the wound were negative, ruling out active infection.
• Despite debridement and irrigation, the wound exhibited underdeveloped granulation tissue.

Findings:

• The patient's C-reactive protein (CRP) levels remained consistently low (peak 0.85 mg/dl) throughout the post-operative period.
• The chest wound showed delayed healing, with epidermal coverage only achieved after 6 months.
• Underdeveloped granulation was a key characteristic of the non-healing wound.

Implications:

• This case suggests that low inflammatory markers (CRP) do not preclude delayed wound healing or complications like dehiscence.
• Further investigation into non-infectious causes of impaired wound granulation post-cardiac surgery is warranted.
• Understanding atypical wound healing patterns is crucial for optimizing patient management and recovery protocols.
