经皮抽吸切除栓子术(PAE)基本器材有:8F导管鞘;特殊制造的5～8 F抽吸导管;50ml注射器;5～8 F顶端呈螺旋的硬性导丝,可通过5～8 F抽吸导管(螺旋尖端能用手和马达转动);硬性导丝顶端装有5～8 F转动网篮。股总动脉顺行穿刺后作诊断性血管造影,股浅动脉插入8 F导管鞘。然后经鞘放入抽吸导管,前端置于栓塞近侧时,用50ml注射器抽吸。陈旧、部分机化栓子,在小动脉内用顶端带螺旋导丝,在较大血管内用网篮式导丝,使栓子破碎,与血管壁的粘连分离后抽吸。PAE后肝素治疗3天,使部分凝血激酶时间保持在40～60秒。102例病人,男46例,女56例,平均年龄74岁(18～79岁)。心源性栓塞88例(86.2%)。下肢严重缺血,按Fontaine分级标准,Ⅱ_b37.8%(38例),Ⅲ21.6%(22例),Ⅳ41.1%(42例)。PAE前多普勒-踝指
Percutaneous Suction Excision and Embolectomy (PAE) The basic equipment is: 8F catheter sheath; specially manufactured 5-8 F suction catheter; 50ml syringe; 5-8 F top of the rigid spiral guide wire can be 5-8 F aspiration catheter (helical tip can be rotated by hand and motor); rigid wire top with 5 ~ 8 F rotating basket. Common femoral artery puncture after diagnostic angiography, superficial femoral artery catheterization 8 F catheter sheath. The sheath was then placed in the aspiration catheter and the front end was placed on the proximal side of the plug with a 50 ml syringe. Stale, partially mechanized emboli, with the top of the small arteries with spiral guide wire, larger vessels with a basket-type guide wire, the embolus broken, and the wall of the vessel after the separation of adhesions and suction. After PAE heparin treatment for 3 days, the partial thromboplastin time to maintain in 40 to 60 seconds. 102 patients, 46 males and 56 females, with an average age of 74 years (18 to 79 years). Cardiac embolism in 88 cases (86.2%). Severe lower extremity ischemia, according to Fontaine grading standards, Ⅱ b37.8% (38 cases), Ⅲ 21.6% (22 cases), Ⅳ41.1% (42 cases). Pre-PAE Doppler - Ankle
