Abstract:

OBJECTIVE: To investigate the material characteristics of the cardiovascular stent-graft and the clinical application of stent placement for the treatment of aortic dissection.
METHODS: Wanfang Database and China Academic Journal Full-text Database were retrieved on computer by the first author using the key words of “aortic dissection; stent-graft; biological materials; clinical research; complications” in Chinese between 1998 and 2010 for articles related to stent-graft treatment for aortic dissection. The repeated study or old literatures were excluded.
RESULTS: According to inclusion and exclusion criteria, 18 literatures were included. Stent-graft is a product of metal or alloy stent endovascular stent with artificial (natural) membrane structure, which is often coated with polyester and biofilm. Polyester is easily obtained, low-cost, but lacks flexibility and can not expand, may induce thrombosis; biofilm has good biocompatibility, and can promote endothelial growth, is the most potential membrane. As for the clinical application curative effect, stent-graft treatment of aortic dissection achieves good results.
CONCLUSION: The endovascular stent-graft can effectively treat Stanford B type/Debakey III type aortic dissection, it is a safe and effective minimally invasive therapy, but long-term effects still need long-term and close follow-up study to be confirmed.
