ABSTRACT
Objective To evaluate the efficacy of ultrasound ablation and balloon angioplasty in treating peripheral arterial occlusion in diabetes mellims. Methods One hundred and fifty-eight patients with peripheral arterial occlusion were treated with the ultrasound ablation. Through percutaneous approach or surgical approach, the ultrasound ablation catheter was inserted into occluded arterial segments. Results The ultrasound ablation was successful in 149 of 158 patients (94%). After treatment, the average skin temperature rised for 3℃ and the distance of intermittent claudicafion was increased for 1 000 m. The gangrene was mitigated in 38 of 45 patients. The pain during rest was ameliorated in 31 of 35 patients. Long-term efficacy was 75%. Conclusion Ultrasound ablation is effective and is a new approach for treating peripheral arterial occlusion in diabetes mellitus.
