Summary
Prosthetic graft infection is a major risk in vascular surgery. Rifampicin-bonded Dacron grafts showed a slight, non-significant reduction in graft infection rates in a multicenter trial.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Biomaterials
Background:
- Prosthetic graft infection is a serious complication in vascular surgery, occurring in 3-5% of reconstructions despite antibiotic prophylaxis.
- Infections lead to high morbidity, mortality, and increased healthcare costs, with challenging management and poor outcomes.
- Aorto-femoral graft infections are common, with bacterial type varying by infection stage (gram-positive early, gram-negative late).
Purpose of the Study:
- To evaluate the efficacy of rifampicin-bonded Dacron grafts in reducing prosthetic graft infections in aorto-femoral surgery.
Main Methods:
- A multicenter randomized controlled trial was conducted.
- Rifampicin-bonded Dacron grafts were compared to standard grafts in aorto-femoral surgery.
Main Results:
- The study demonstrated a reduction in total early wound and graft infection rates.
- At 2-year follow-up, a small, non-significant reduction in graft infection was observed (1.7% vs. 2.3%).
- Similar results were reported in two other independent multicenter trials.
Conclusions:
- Rifampicin-bonded Dacron grafts may offer a potential benefit in reducing early infection rates.
- Further research is needed to confirm long-term efficacy and clinical significance.
