Abstract: BACKGROUND: With the increasing incidence of vascular diseases, the clinical application of vascular stents combined with minimally invasive treatment surgery is widely used.
OBJECTIVE: To describe the research background, performance requirements, types, raw materials, production and modification techniques of endovascular stents, and analyze the complications and improvement methods after the endovascular stent implanted in the human body.
METHODS: The databases of CNKI and Web of Science were searched, and the search time period was from 2005 to 2020. The key words were “vascular stent, aneurysm, endovascular exclusion, research status” in English and Chinese. 
RESULTS AND CONCLUSION: The use of endovascular stents combined with minimally invasive treatment for aneurysms is very important in clinic. Traditional vascular stents cannot have good long-term patency rate, durability, anti-thrombosis and anti-tumor functions at the same time; it should be systematically designed and improved from the aspects of structural design, endothelialization, and functional modification of high effective drug release. The study of endovascular stents is a cutting-edge research involving multidisciplinary interdisciplinary research. To develop vascular stents with more biocompatible, more stable, and lower costs, the collaborative innovation of a multidisciplinary team of talents in biological materials, engineering technology and clinical medicine is important, so as to contribute to the medical cause of human beings.

Key words: materials, stents, vascular stents, aneurysms, research status, endothelialization, anti-thrombosis, review
