Abstract:

OBJECTIVE: To explore mechanism, prevention and treatment of thrombosis following implantation of coronary artery stent.
METHODS: The first author used computer to retrieve Vip Database (http://www.cqvip.com/) for articles concerning thrombosis following implantation of coronary artery stent published from January 2000 to October 2009. The key words included “coronary artery, stent implantation, thrombus”. The data were primarily screened, and references of each article were checked. Inclusion criteria: mechanism and risk factor of thrombosis in stent; prevention and treatment of thrombosis in stent. Exclusion criteria: articles addressing duplicated or old contents. Finally, 28 articles were included.
RESULTS: Thrombosis in stent was a severe complication in interventional therapy of coronary artery disease, could induce severe outcomes for the body. Compared with common mental stent, drug eluting stents can significantly reduce restenosis rate and revascularization rate of target lesions. Following stent implantation, thrombosis in stent can occur in early, late and extremely late phases. The mechanisms are different. Antiplatelet, anticoagulation and lipid-lowering therapy can diminish the occurrence rate of thrombosis in stent. Individual surgery and individual drug therapy not only can solve revascularization in the coronary artery, but also decrease restenosis rate and occurrence rate of thrombosis in stent.
CONCLUSION: With the expectation of novel stents, various risk factors for thrombosis in stent should be assessed in detail to achieve individual surgery and individual drug therapy. During revascularization in the coronary artery, restenosis rate and occurrence rate of thrombosis in stent should be reduced.
