: Percutaneous coronary intervention (PCI) of chronic total occlusion (CTO) can be challenging, but high success rates (85-90%) are currently achieved at experienced centers with approximately 3% risk for a major periprocedural complication.: CTO PCI complications can be categorized according to location such as cardiac and non-cardiac (vascular access complications, thromboembolic complications, contrast-related and radiation injury) complications. Cardiac complications are further subdivided into coronary (acute closure, perforation, and equipment loss or entrapment) and non-coronary (hypotension, myocardial infarction, tamponade, arrhythmias).: In this article, we review strategies to prevent and treat CTO PCI complications. Careful monitoring throughout the case enables prevention and early detection of a complication. If a complication occurs, rapid implementation of treatment using an algorithmic approach can minimize its adverse impact.
经皮冠状动脉介入治疗（PCI）慢性完全闭塞（CTO）可能具有挑战性，但在经验丰富的中心，目前成功率高达 85-90％，围手术期主要并发症的风险约为 3％。CTO PCI 并发症可根据部位进行分类，如心脏和非心脏（血管入路并发症、血栓栓塞并发症、对比剂相关和辐射损伤）并发症。心脏并发症进一步细分为冠状动脉（急性闭塞、穿孔和设备丢失或嵌顿）和非冠状动脉（低血压、心肌梗死、心脏压塞、心律失常）并发症。在本文中，我们回顾了预防和治疗 CTO PCI 并发症的策略。在整个手术过程中进行仔细监测可预防和早期发现并发症。如果发生并发症，使用算法方法快速实施治疗可以最大程度地减少其不良影响。
