经皮冠状动脉介入(PCI)治疗已经成为冠心病患者冠脉血运重建的主要手段。第二代金属药物洗脱支架(DES)虽然较以往裸金属支架显著减少了支架内再狭窄和靶病变再次血运重建的发生率,但仍不能从根本上解决支架长期存留带来的问题。新型可吸收支架早期提供血管支撑,随后完全消失,从根本上克服了支架永久存留的不足,成为目前心血管介入领域研究的焦点。本文就目前主要的全吸收式血管支架的种类及相关临床研究进行概述。
Percutaneous coronary intervention (PCI) has become the main means of coronary revascularization in patients with coronary heart disease. Although the second-generation metal-drug-eluting stent (DES) significantly reduces the incidence of in-stent restenosis and re-revascularization of target lesion compared with the bare metal stent, it still can not fundamentally solve the problem caused by the long-term retention of the stent. The new type of absorbable stent provides vascular support early, and then disappear completely, thus fundamentally overcoming the shortcomings of permanent stent has become the focus of the current field of cardiovascular intervention. This article summarizes the current major types of total-absorption stent and related clinical studies.
