自从1987年首次在髂股动脉和胭动脉内使用Simpson 外周血管切削器(Atherocath)以来,它的应用已日益增多。但此类导管越过较弯曲的成锐角的髂外和髂总动脉时易被阻挡,产生明显的阻力或使切削组件不能顺利推进,强行推进可损伤动脉。作者使用长25～70cm 的血管鞘行动脉内膜切除导管的导入和定位。动脉内膜切除导管要求有一个带止血阀的套鞘来插入血管。股腘动脉和髂外动脉中远段的狭窄使用标准的短的10～13cm 血管鞘。依从股动脉穿刺点到病变处的距离,髂总动脉和近 Its use has been increasing since the Simpson Atherocath was first introduced in the iliac and popliteal arteries in 1987. However, such catheters can easily be blocked when they cross the more tortuous acute external iliac and common iliac arteries, causing obvious resistance or preventing the cutting components from advancing smoothly. Impulsive advancement can damage the arteries. The authors used a length of 25 ~ 70cm vascular sheath endarterectomy catheter for the introduction and positioning. Endarterectomy catheters require a cuff with a hemostatic valve to be inserted into the blood vessel. The stenosis of the distal mid-femoral artery and the external iliac artery uses a standard short 10-13 cm vascular sheath. Follow the femoral artery puncture point distance to the lesion, common iliac artery and
