Abstract

Fresh autologous vein grafts are commonly used for infrainguinal vascular reconstructions with good results. Previously we have confirmed the high viability index of homografts even after long-term storage at 4°C in tissue culture medium. In this clinical study, we have evaluated the in vivo efficiency of this storage method in humans with major peripheral graft infections. Between April 2006 and November 2008, data from patients who underwent graft excision and venous allograft reconstruction were collected prospectively (5 men, 2 women, mean age 68 years). Six patients had acute ischemia at the time of allograft reconstruction, while 3 had experienced anastomosis rupture. Allograft reconstruction was performed as an emergency procedure in 3 cases. The observed parameters included patient survival, limb salvage, persistence or recurrence of infection and allograft patency. In the follow-up period reoperation, excision or thrombectomy was necessary in 3 cases. There were no perioperative deaths, early amputations, persistent or recurrent infections. In conclusion, this study demonstrates the efficacy of long-term 4°C storage of venous allografts for revascularization in cases with peripheral bypass graft infection. We suggest that this technique is a useful option for graft preservation and propose a wide-scale introduction.
