Late-acquired angiographic coronary aneurysm formation after drug-eluting stent implantation is a rare phenomenon but potentially life-threatening event that has become a major cause of concern. Optical coherence tomography (OCT) is a high-resolution imaging method that allows detailed evaluation of stent strut coverage and characterization of neointimal tissue. This case report describes the possible mechanism of late-acquired angiographic coronary aneurysm formation after bare-metal stent implantation using OCT and intravascular ultrasound.
药物洗脱支架植入术后迟发性血管造影冠状动脉瘤形成是一种罕见但可能危及生命的现象,已成为主要关注原因。光学相干断层扫描(OCT)是一种高分辨率成像方法,可对支架小梁覆盖情况进行详细评估,并对新生内膜组织进行特征描述。本病例报告使用OCT和血管内超声描述了裸金属支架植入术后迟发性血管造影冠状动脉瘤形成的可能机制。
