主动脉狭窄性病变血管内支架植入术的临床观察

目的对主动脉狭窄性病变的血管内支架(ES)植入术进行疗效观察与评价.方法 14例主动脉狭窄患者,包括大动脉炎(TA)10例,动脉粥样硬化(AS)1例,先天性主动脉缩窄(CoA)3例,均行经皮血管内支架植入术.术后随访10～102个月.结果 14例血管内支架植入术治疗成功率为100%.术后即刻疗效好,跨狭窄处收缩压差由术前(70.00±24.33) mmHg降至(2.43±3.76)mmHg(P<0.01),术前与术后主动脉狭窄段最窄处直径由(5.57±1.45)mm增至(12.28± 2.09)mm(P<0.01).随访12例疗效满意;1例TA转为活动期;1例CoA症状反复行外科手术治疗.结论血管内支架植入术治疗主动脉狭窄性病变可获得满意的临床效果.

Endovascular implantation stents for stenosis of aorta

Objective To evaluate the efficacy of endovascular stent implantation for the treatment of stenosis of aorta. Methods Fourteen cases of stenosis of aorta including 10 with Takayasu's arteritis (TA), 1 with atherosclerosis and 3 with coarctation of aorta (CoA), underwent endovascular stents implantation. The patients were followed-up for 10 to 102 months. Results Immediate success after stents implantation was achieved in all patients. Stents implantation produced a significant decrease in the systolic pressure gradients from (70.00±24.33) mmHg to (2.43±3.76) mmHg (P<0.01) and a significant increase in the lumen diameters from (5.57±1.45) mm to (12.28±2.09) mm (P<0.01). The results of follow-up data indicated the efficacy of 12 cases was stable, and there was no relapse. One case with TA was reactive. One case with CoA relapsed after stent implantation. Conclusion Stents implantation for stenosis of aorta is safe and effective, worth expanding in clinic.
