A clinical application of the Omniflow II collagen-polymer vascular prosthesis in a polytetrafluoroethylene graft infection case

摘要

The Omniflow vascular prosthesis is a collagen--polyester composite which has been used successfully for peripheral arterial reconstruction.In this study we present a clinical application of the Omniflow II collagen-polymer vascular prosthesis in a polytetrafluoroethylene graft infection case Introduction Arterial reconstruction is the most important surgical strategy for patients with arteriosclerotic obstruction in the lower limbs. One of the most feared complications of the vascular bypass procedures using traditional prosthetic grafts such as polytetrafluoroethylen (PTFE) and polyethylene tetraphthlate (Dacron) is the appearance of infection after implant. Wound dehiscence with exposure of the lower anastomosis is a limb- and life-threatening complication of femorodistal bypass[1]. Virulent graft infections presenting with sepsis or anastomotic dehiscence should continue to be treated with total graft excision[2]. Case Presentation Our case was a 62-year-old male. He had undergone right femoropopliteal bypass surgery with 6 mm ringed polytetrafluoroethylene graft 6 months ago. One month after the surgery he had undergone another procedure for hematoma extraction at femoral region. This time he was admitted to our hospital with complaint of protrusion of the synthetic graft from the skin over the midportion of the subcutaneous tunnel for 10 days, probably secondary to destruction of the cutaneous tissue overlying the graft (Figures 1&2).
