Long-term results of cryopreserved allografts in aortoiliac graft infections

ObjectiveDifferent graft materials have been proposed for in situ reconstruction the setting of vascular infection (VGI). We analyzed long-term outcomes after aortoiliac with cryopreserved allografts.MethodsWe performed a retrospective analysis patients who had undergone arterial allografts VGI from 2000 to 2015. The end points were perioperative and mortality graft-related complications, including stenosis, occlusion, pseudoaneurysm, reinfection.ResultsA total 33 (91% male) median age 67 years (range, 53-83 years) allografts. 30-day was 6% (n = 2); both deaths related allograft (one early allograft–enteric fistula one rupture). Another two experienced (≤30 days) events limb occlusion), an complication rate 12% 4). Of 31 discharged patients, 13 (42%) died 47 months 2-97 months). follow-up 18 remaining 96 10-146 estimated survival at 1, 3, 5 88%, 81%, 66%, respectively. Nine (29%) least following during follow-up, stenosis requiring intervention five (16%), occlusion four (13%), pseudoaneurysm three (10%), reinfection (6%). freedom any first event 78%, 71%, 62%, primary patency assisted 1 3 87% 79%, 90% 83%, respectively.ConclusionsIn treat associated relevant complications. Although acceptable, other complications frequent long term, particular, stenosis.
