简要总结
This trial is aimed to evaluate the safety and efficacy of DCB in treating AVF stenosis in chinese population.
详细描述
For years, first-line treatment of AVFs stenoses has been percutaneous transluminal angioplasty. However, restenosis and reintervention rates remain incredibly high and occur, according to recent studies, in up to 60% and 70% of patients at 6 and 12 months, respectively. Drug-coated balloons delivering paclitaxel at the angioplasty site have proved their superiority in the treatment of coronary and peripheral arterial stenoses. Paclitaxel reduces neointimal hyperplasia and drug-coated balloons,therefore, it represents an attractive option for AVF stenoses.

结局指标
主要结局
primary patency of target lesion in 6 months
时间窗: 6 months
Primary Patency is defined as the freedom of reintervention for the target lesion,including: 1)clinical driven target lesion reintervention;2)thrombus formation in target lesion; 3) surgical removal of target lesion;4) AVF was abandoned because of the target lesion could not be retreated
次要结局
- primary patency of target lesion in 12 months(12 months)
- number of reinterventions(12 months)
- device success(during the procedure)
- clinical success(5 days)
- Procedural Success(2 weeks)
