Methods A total of 40 cases of peripheral arterial disorders,including 23 thromboangiitis obliterans (31 limbs) and 17 arteriosclerosis obliterans (23 limbs),were treated by a self-made vacuum-compression therapeutic apparatus. Results The effective rate in thromboangiitis obliterans and arteriosclerosis obliterans groups was 96.77% and 92.23%,respectively. The cuffs on the apparatus were improved to eliminate discomfort in the patients during treatment. "Rebound symptom" was observed during treatment,which had not been reported previously. Conclusion Vacuum-compression therapy has a good prospect for treating ischemia of the extremities.展开更多
