Management of infected lower extremity autologous vein grafts by selective graft preservation.
Between 1975 and 1991, we treated 16 patients with infected lower extremity autologous vein grafts performed for limb salvage by complete graft preservation. Traditional treatment of these infections includes immediate graft excision and complex revascularization procedures to prevent limb loss. The infection involved an intact anastomosis in 12 patients or the body of a patent graft in 4 patients. None of the patients was systemically septic. All patients were treated with appropriate intravenous antibiotics. Six patients were treated by placement of autologous tissue on the exposed graft (4 rotational muscle flaps, 2 skin grafts), and 10 were treated with antibiotic-soaked dressing changes and repeated operative débridements to achieve delayed secondary wound healing. This treatment resulted in a 19% (3 of 16) mortality rate and an 8% (1 of 13) amputation rate in survivors. Of the six patients managed by autologous tissue placement onto the infected graft, five patients had wounds that healed without complications, and one died of a myocardial infarction. Of the 10 patients treated by delayed secondary wound healing, 2 developed anastomotic hemorrhage, which resulted in death in 1 patient and above-knee amputation in the other, 1 died of a myocardial infarction, 1 developed graft thrombosis, and 6 had wounds that healed. Placement of autologous tissue to cover an exposed, infected patent vein graft with intact anastomoses may prevent graft dessication, disruption, and thrombosis, which renders graft preservation an easier, safer method of treatment compared with routine graft excision.
