Pedicled omentum, after lengthening, was transferred to the ischemic lower limbs of 12 patients with Buerger's disease to assess its capacity to improve the blood supply to these compromised extremities. The immediate (after one month) and long-term (9-12 months) results were encouraging. After one month, rest pain had diminished in 83% of cases, claudication was relieved in 75% of cases, temperature became normal in all cases (100%) and ischemic ulcers either healed or showed signs of healing in 83% of cases. During long-term follow up (after 9-12 months), the results deteriorated slightly, but they remained promising. Rest pain had disappeared in 80% of cases. Claudication was still relieved in 70% of cases, temperature was still improved in 60% and ulcers had healed completely in 67% of cases.
