Ultrasound ablation and balloon angioplasty in treating peripheral arterial occlusion in diabetes mellitus / 中华内分泌代谢杂志

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.

Ultrasonic ablation in chronic deep vein thrombosis of lower extremities / 介入放射学杂志

Objective To evaluate the clinical efficacy of ultrasonic ablation in patients with chronic deep vein thrombosis of lower extremities. Methods Fifty-six patients with chronic deep vein thrombosis resulting in total occlusion of iliac-femoral veins accepted intra-venous ultrasonic ablation. The time for ultrasonic ablation was 12-24 minutes with the mean being 18 minutes. After the procedure, anti-coagulation was performed through the retaining catheters and venous propeller was utilized for promoting blood reflow. Results Ultrasonic ablation easily created a channel within the occlusive iliac-femoral veins and achieved successful recanalization in 49 of 56 patients (87.5%). Five patients (8.9%) were partially re-canalized and 2 (3.6%) had no recanalization. Thirty-eight of the 49 re-canalized patients were followed up, including 22 with no stent placement showed 9 (40.9%) re-occlusion and 16 received stent placement, and 2 had (12.5%) re-occlusion. Conclusions Intravascular ultrasonic ablation is an effective therapeutic modality to recanalize chronic thrombosed occlusion of iliac-femoral veins and can lay down a foundation for further balloon-expansion or stent-placement with long term patency.
