Omental autotransplantation in treatment of thromboangiitis obliterans.

: From 1981 to 1985, omental autotransplantation was performed for 28 patients with thromboangiitis obliterans on the left lower extremities in 16 patients, the right ones 11, and the right upper limb 1. The early results in all patients were satisfactory. In 19 patients followed up from 1 to 4 years, the results were encouraging, with the improvement of symptoms after operation. In 18 patients, digital ulcers healed within 2-4 weeks. Doppler and electrical impedance plethysmography examinations showed the blood circulation of affected extremities was markedly improved in the 18 patients except one who had the recurrence of digital ulcer 2 years later. In one of the 19 patients the disease recurred one month after the operation, and a lumbar sympathectomy was performed. The indications, the operative technique, and the mechanism of this operation are discussed.
