By convention, a total obstruction of the coronary artery with no flow at the occluded segment that has been present for at least 3 months is termed as chronic total occlusion or CTO. This is to be distinguished from a sudden occlusion of the coronary artery lumen by a thrombus during an acute myocardial infarction. Percutaneous coronary intervention (PCI) of CTO is increasingly being performed by interventional cardiologists with improved success rates. In this article, the focus will be on antegrade techniques that will assist the operator to maximise the success rates and to minimise the complications.
按照惯例，冠状动脉完全阻塞，闭塞节段无血流且持续至少3个月，被称为慢性完全闭塞（CTO）。这要与急性心肌梗死期间血栓导致的冠状动脉管腔突然闭塞相区分。介入心脏病学家越来越多地对慢性完全闭塞病变进行经皮冠状动脉介入治疗（PCI），且成功率有所提高。在本文中，重点将放在正向技术上，这些技术将帮助操作者最大化成功率并最小化并发症。
