超声溶栓治疗急性周围动脉血栓形成(附6例报告)

目的　评价血管内超声溶栓治疗急性周围动脉血栓形成的疗效。方法　 6例患者经血管造影证实的股浅动脉血栓形成 3例、动脉血栓形成 2例、肱动脉血栓形成 1例 ,对下肢动脉血栓采用对侧或同侧股动脉穿刺 ,插入超声导管溶栓 ,对上肢动脉血栓采用股动脉穿刺 ,插入超声导管至上肢动脉溶栓。对 6例患者均进行 4～ 6min血管内超声溶栓治疗。结果　治疗后即刻造影显示血管内超声成功地溶解了 6例患者动脉内血栓 ,治疗 2 4h后有 1例患者发生了动脉再次血栓形成 ,其余 5例患者无再次血栓形成发生。结论　血管内超声溶栓可以有效地治疗周围动脉血栓形成。

Ultrasonic Angioplasty in Treatment in Thrombosis of Peripheral Arteries

Objective To examine the clinical feasibility of ultrasonic thrombolysis in totally occluded peripheral arteries. Methods The ultrasonic thrombolysis was performed in 3 patients totally occluded femoral arteries 2 patients totally occluded popliteal arteries and 1 patient totally brachial artery. The ultrasonic thrombolysis device consisted of acolysis ultrasonic unit and 1.6mm diameter flexible wire. Results The thrombolysis was successful in 6 patients after treatment and thrombosis was recurrent in 1 case 24h after treatment. Damage of arterial wall was not shown in all patients. Conclusion The results suggest that ultrasonic thrombolysis might be a safe and effective catheter-based therapeutic modality for patient with occluded peripheral arteries. Ultrasonic energy could not appear to cause injury of intima of peripheral artery.
