由于旋切术（RA）有几种独特的并发症，如毛刺截留、血管穿孔和血流缓慢，因此介入心脏病专家必须熟悉此类并发症的急救程序。紧急手术的主要部分是在手术过程中将导丝保持在目标冠状动脉中。但是，由于RA导丝的长度为300 cm，在去除毛刺的过程中，不容易将导丝保持在同一位置，并且去除毛刺需要主术者和助手之间的协作。我们描述的情况下，一个83岁的男性稳定型心绞痛。我们对左前降支动脉进行了RA，并使用KUSABI（Kaneka Meidong Corporation，OSAKA，Japan）捕获球囊技术取出了磨头，但未激活dynaglide模式。这种简单的技术将帮助RA操作者比传统的去除技术更可靠地去除毛刺。
Because rotational atherectomy (RA) has several unique complications, such as burr entrapment, vessel perforation, and slow flow, it is important for interventional cardiologists to be familiar with bailout procedures for such complications. The principal part of bailout procedures is to keep a guidewire in the target coronary artery during the procedure. However, it is not easy to keep a guidewire in the same position during the removal of a burr because the length of the RA guidewires is 300 cm, and the removal of a burr requires collaboration between the primary operator and an assistant. We describe the case of an 83-year-old male with stable angina. We performed RA to the left anterior descending artery, and removed the burr using a KUSABI (Kaneka Medix Corporation, OSAKA, Japan) trapping balloon technique without activating the dynaglide mode. This simple technique would help RA operators remove a burr more reliably than the conventional removal technique.
