Post-operative wound and vascular graft infection caused by Haemophilus parainfluenzae

Introduction: We present a rare case of wound and vascular graft infection caused by Haemophilus parainfluenzae after reconstruction of the femoral artery bifurcation. Case presentation: H. parainfluenzae was isolated from pus samples taken from a patient who had undergone angioplasty of the superficial femoral artery and anastomosis with a synthetic graft. The pathogen was isolated from samples taken from both the wound and the graft. Management involved wide surgical debridement and irrigation, preservation of the prosthetic graft and transposition of muscle flaps in conjunction with the administration of culture-based antimicrobials. Conclusion: H. parainfluenzae surgical wound and vascular graft infections are uncommon, and quick diagnosis and preservation of the graft is of great importance in treatment.
