1977年瑞士Gruentzing成功地进行了世界上第1例经皮冠状动脉腔内成形术(Percutaneous transluminal coronary angio-plasty,PTCA),此后,PTCA作为一项重要的冠心病血管重建技术迅速在世界范围内推广应用。但PTCA术后急性血管闭塞发生率为2%～11%。约30%～50%的患者在PTCA术的3～6个月发生再狭窄。1987年,Sigwart首先将冠状动脉支架置入术应用于临术,明显减少了再狭窄的发生率。根据BE- In 1977, Gruentzing in Switzerland successfully performed the world’s first Percutaneous Transluminal Coronary Angioplasty (PTCA). Since then, PTCA has rapidly become an important global coronary revascularization technology Promote the application. However, the incidence of acute vascular occlusion after PTCA is 2% ~ 11%. About 30% to 50% of patients undergo restenosis 3 to 6 months after PTCA. In 1987, Sigwart first applied coronary stenting to surgery, significantly reducing the incidence of restenosis.
