This case outlines an unusual complication of coronary intervention, the likely mechanisms leading to this and possible retrieval options. It is the first case to the best of our knowledge reporting this complication. A 78-year-old Caucasian man underwent coronary stenting. During the procedure kinking and subsequent fracture of a non-compliant percutaneous transluminal coronary angioplasty (PTCA) balloon occurred. Injection of contrast down the guide to opacify the coronary arteries resulted in 'inflation' of the balloon with air, and embolisation of the inflated balloon into the proximal left anterior descending artery. The embolised balloon was retrieved by removal of the guide catheter and wire as a unit. The patient had a good angiographic outcome. This case highlights risks associated with usage of kinked balloons catheters, and describes for the first time to our knowledge, the inflation of a PTCA balloon with air from its shaft within the catheter, causing 'floatation' embolisation into the coronary artery.
本病例概述了冠状动脉介入治疗的一种罕见并发症、导致该并发症的可能机制以及可能的取出方法。据我们所知,这是首例报告该并发症的病例。一名78岁的白种男性接受了冠状动脉支架置入术。在手术过程中,一个非顺应性经皮腔内冠状动脉成形术(PTCA)球囊发生了扭结并随后断裂。通过导管注入造影剂使冠状动脉显影,导致球囊内充入空气而“膨胀”,并且膨胀的球囊栓塞至左前降支近端。通过将导引导管和导丝作为一个整体取出,成功取出了栓塞的球囊。该患者获得了良好的血管造影结果。本病例突出了使用扭结球囊导管相关的风险,并且据我们所知首次描述了PTCA球囊从其在导管内的轴杆充入空气,导致“漂浮”栓塞至冠状动脉。
