经皮冠状动脉腔内成形术(PTCA)和支架置入术已成为冠心病血管重建的重要手段,疗效确定,但一些复杂病变仍然是目前冠心病介入治疗的难点,主要原因是复杂冠状动脉病变介入治疗存在着风险性高、再狭窄率高、并发症多、成功率低及对术者要求高等特点。我们通过运用锚定技术治疗冠状 Percutaneous transluminal coronary angioplasty (PTCA) and stenting have become an important means of revascularization of coronary heart disease, and the curative effect is confirmed. However, some complicated lesions are still the difficult point of interventional therapy of coronary heart disease, mainly due to complicated coronary artery disease Interventional therapy has the characteristics of high risk, high restenosis rate, multiple complications, low success rate and higher demands on the surgeon. We treat the coronas by applying anchoring techniques
