Stents are the most important advance for percutaneous coronary revascularization. After introduction of drug eluting stents, in-stent restenosis ist not more a major problem of coronary intervention. However, restenosis by bare metal stents, peripheral embolism following stent implationtan in old vein grafts, and conditions in which there is a discontinuity of the coronary lumen (rupture or perforation, aneurysm, and fistula) remain a problem in interventional therapy. Stent grafts with integration of a membrane into a coronary stent represent an interesting concept to possibly prevent intraluminal proliferation, to seal degenerated vein grafts, and to cover coronary artery perforations, symptomatic aneurysms, and fistula with high success and acceptable rates of acute complications. We presents case reports and a review article.
支架是经皮冠状动脉血运重建最重要的进展。药物洗脱支架引入后，支架内再狭窄已不再是冠状动脉介入治疗的主要问题。然而，裸金属支架导致的再狭窄、旧静脉移植物支架植入后发生的外周栓塞，以及冠状动脉管腔连续性中断（破裂或穿孔、动脉瘤和瘘管）的情况，仍然是介入治疗中的问题。将膜整合到冠状动脉支架中的支架移植物是一个有趣的概念，有可能预防管腔内增生、封闭退化的静脉移植物，并覆盖冠状动脉穿孔、有症状的动脉瘤和瘘管，成功率高且急性并发症发生率可接受。我们展示了病例报告和一篇综述文章。
