Interventional minimally-invasive techniques, including percutaneous transluminal angioplasty and endovascular stent placement, have become one of the most effective methods to treat the vascular stenosis and occlusion. Compared to traditional surgical treatment, interventional treatment has many advantages. It is mini-invasive and highly effective with high technical success rate, and the patient' s hospitalization time is shorter. However, the occurrence of restenosis after stent placement is up to 20%-50% high, which has significantly affected the mid-term and long-term effectiveness. Nowadays, the research into the prevention of vascular restenosis after stent placement has become the hot spot in both clinical and fundamental medical field. This paper aims to make a detailed review of the research progress in the prevention of vascular restenosis developed after stent placement. (J Intervent Radiol, 2011 , 20: 665-668)
