To evaluate the use of stent-grafts for the percutaneous closure of arteriovenous fistulas that develop after cardiac catheterization.
From January 1994 to November 1997, 14 arteriovenous fistulas in 13 patients (eight men, five women; age range, 46-65 years; mean age, 53.5 years) were treated. Eleven fistulas were situated between the deep femoral artery and the common femoral vein, and three fistulas were between the superficial femoral artery and the common femoral vein. All fistulas were closed with stent-grafts positioned in the artery at the level of the fistula.
The percutaneous treatment of arteriovenous fistulas was successful in all cases. The findings at angiography performed after the procedure demonstrated the closure of the fistulas and the correct positioning of the prostheses; veins were no longer visible. One complication occurred--a partial thrombosis of the common femoral vein at the puncture site after manual compression.
On the basis of the preliminary data, the authors believe that the percutaneous closure of arteriovenous fistulas with stent-grafts is a safe and effective alternative to conventional surgery.
评估使用覆膜支架经皮闭合心脏导管插入术后形成的动静脉瘘。
1994年1月至1997年11月，对13例患者（8例男性，5例女性；年龄范围46 - 65岁，平均年龄53.5岁）的14处动静脉瘘进行了治疗。11处瘘位于股深动脉与股总静脉之间，3处瘘位于股浅动脉与股总静脉之间。所有瘘均通过将覆膜支架置于瘘口水平的动脉内进行闭合。
所有病例经皮治疗动静脉瘘均获成功。术后血管造影结果显示瘘口闭合且假体位置正确；静脉不再显影。发生了1例并发症——手动压迫后穿刺部位股总静脉部分血栓形成。
基于初步数据，作者认为使用覆膜支架经皮闭合动静脉瘘是传统手术的一种安全有效的替代方法。
