血管内支架植入治疗动脉和静脉狭窄性疾病的疗效比较

Comparison on curative effect of intravascular stent therapy for vascular stenosis

目的比较血管内支架植入术治疗动脉和静脉血管狭窄性疾病的近、远期疗效。方法动、静脉狭窄性疾病分别以肾动脉狭窄（RAS）和布-加综合征（BCS）为例,回顾性分析22例RAS和46例BCS的血管内支架植入治疗的疗效,并比较其治疗3个月后发生再狭窄的情况。结果22例RAS和46例BCS接受血管内支架植入治疗后症状均有不同程度减轻,术后重复造影显示狭窄部位均消失,术后随访3年分别发生再狭窄6例和8例。结论动脉和静脉血管狭窄性疾病行血管内支架植入术的近期疗效（3个月内）均良好,远期疗效（3个月～3年）略差。

Objective To investigate the effective therapy method of percutaneous transluminal angioplasty and intravascular stent （PTAS） in the arterial and vein stenosis, and to compare their curative effect. Methods Taking the renal artery stenosis （RAS） in arterial stenosis and Budd-Chiari syndrome （BCS） in vein stenosis for examples, 22 cases of RAS and 46 cases of BCS were retrospective studied to compare their therapy effect and restenosis after treating by PTAS 3 months. Results The syndrome of all the cases was relieved, the vascular stenosis disappeared in postoperative angiography. The restenosis occurred respectively in 6 of 22 RAS patients and 8 of 46 BCS patients in 3 years after operation. Conclusion The therapy effect of PTAS in short-term （3 months） was good, while that was relatively unsatisfactory in long-term （3 months to 3 years）.
