T/NBPIA 012-2024 Blood dialysis access balloon dilatation catheter classification criteria

Scope

Main technical content: Balloon angioplasty is a technique that uses balloon dilatation catheters and other devices to dilate and reshape stenotic lesions in the vascular lumen. It is currently the first-line treatment for stenosis of vascular pathways. The balloon dilatation catheter is the key device for balloon angioplasty, and the performance and characteristics of the balloon dilatation catheter largely determine the clinical success rate of the surgery and the frequency and severity of postoperative restenosis. However, due to the structural characteristics of vascular pathways, there are special requirements for the balloon dilatation catheters used in surgery. The pathophysiological basis of stenosis of hemodialysis pathways is different from that of other peripheral vascular stenosis. In addition to neointima, fibrosis and puncture-related scar proliferation are significant, and the characteristics of the balloon dilatation catheters required for balloon angioplasty are also different from those in other peripheral vascular fields. It is necessary to classify the balloon dilatation catheters from different dimensions. The characteristics of the balloon dilatation catheters determine whether balloon angioplasty can achieve clinical and technical success, and also determine the frequency and severity of postoperative restenosis. By selecting appropriate balloon dilatation catheters, we can improve the success rate of surgery, reduce surgical trauma, reduce the frequency and severity of vascular pathway complications, fully protect patients' vascular resources, and prolong their survival time.
