血管内超声消融治疗老年下肢动脉硬化闭塞症

Intravascular ultrasonic ablation for atherosclerosis obliterrans

目的评价血管内超声消融治疗下肢动脉硬化闭塞症的疗效. 方法 20例下肢动脉硬化闭塞症患者在数字减影血管造影监测下行腔内超声消融治疗,术后抗凝. 结果消融闭塞血管长度10～20 cm,动脉管腔平均扩张约60%,术中造影证实闭塞动脉复通,术后2周测踝/肱指数提高0.20～0.45. 结论超声消融可以有效消融动脉硬化斑块,重建闭塞动脉血流,为动脉闭塞的患者提供治疗新方法.

Objective To evaluate the effect of ultrasonic ablation in treating atherosclerosis obliterrans （ASO）. Methods Twenty patients with ASO in lower limbs were confirmed by angiography, all of which underwent ultrasonic ablation under digital subtraction angiography（DSA）. Anticoagulant therapy was used after operation. Results All the occlusive arteries achieved re-canalitation. The arteries were expanded by 60%, and ankle/brachia indices were improved by 0.20-0.45. Conclusions Ultrasonic ablation is a new,safe and effective method for treating ASO. It can dissolve atherosclerosis and recover the flow in peripheral arteries.
