简要总结
The purpose of this study is to determine whether the use of drug-eluting balloons is effective in the treatment of (re)stenosis in dialysis fistulae.
详细描述
Drug-eluting devices have proved beneficial in the treatment of stenosis in native coronary and lower limb arteries. Stenosis and restenosis is a known problem in dialysis fistulae and drug-eluting devices might be beneficial in this field as well.
In the procedure a conventional balloon is passed through the stenosis which is then dilated. After this patients are randomized before a second dilatation with either a conventional balloon or a drug-coated balloon.
The stenosis is evaluated preoperatively and followed up by means of ultrasound by a vascular technician. Follow-up will end at 12 months.
