Abstract: Hemodialysis access stenosis is one of the most common complications in hemodialysis patients.Endovascular intervention has become the first choice for the treatment of vascular stenosis，but restenosis after endovascular intervention has become a difficult problem in the field of hemodialysis access.According to the location，restenosis can be divided into peripheral restenosis and central venous restenosis.The treatment methods include percutaneous transluminal angioplasty，percutaneous transluminal stent implantation，open surgery and so on.With the development of new technology，there are many new treatment options for restenosis，such as drug-coated balloon，stent graft，hemodialysis reliable outflow graft device and so on.The patency rate of restenosis treatment can be improved by reasonable selection and usage of these new methods.
