目的 探讨血栓消融新技术治疗急性肺栓塞的疗效。方法 对 1例急性左肺动脉巨大栓塞患者先用尿激酶 10 0万单位静脉滴注溶栓 ,经肺动脉造影证实血栓未被溶解后 ,采用血栓消融导管 ,经股静脉插至左肺动脉血栓处 ,以高压氧气为动力 ,导管内置叶片高速旋转 ,产生强大涡流 ,将血栓吸入导管并粉碎 ,经消融后肺动脉造影 ,血栓处已有 5 0 %再通 ,再局部注射尿激酶 5 0万单位 ,下腔静脉置入滤器 1只 ,以后每日静脉滴注尿激酶 5 0万单位 ,共 7天 ,并用肝素及华法令抗凝治疗。结果 经导管消融治疗后患者胸闷、呼吸困难等症状迅速缓解。 2 0天后经CT检查左肺动脉血栓已溶解。随访至今近 6个月 ,病人情况良好。结论 应用血栓消融导管使血栓碎解这项新技术加溶栓治疗左肺动脉主干栓塞获得成功 ,为肺栓塞的治疗提供了新的有效途径
Objective To investigate the therapeutic effect of thrombus ablation on acute pulmonary embolism. Methods Thrombolysis catheter was inserted into the left pulmonary artery thrombosis by a thrombolysis catheter after thrombolytic catheter was confirmed by pulmonary arteriography in 1 case of acute left pulmonary artery occlusion. High-pressure oxygen as the driving force, the catheter built-in blades rotate at high speed, resulting in a strong vortex, the thrombus into the catheter and crushed by pulmonary artery angiography after ablation, Thrombosis 50% recanalization, and local injection of urokinase 500,000 units, Venous into the filter 1, after a daily intravenous infusion of urokinase 500,000 units for a total of 7 days, and anticoagulant therapy with heparin and warfarin. Results After the catheter ablation, patients with chest tightness, difficulty breathing and other symptoms quickly relieved. Twenty days after CT examination of left pulmonary artery thrombosis has been dissolved. Nearly 6 months follow-up, the patient is in good condition. Conclusion The thrombolytic catheter thrombolysis thrombolysis of this new technology plus thrombolysis in the treatment of left pulmonary artery embolization was successful, providing a new effective way for the treatment of pulmonary embolism
