Iatrogenic aortic dissection (IAD) is a rare complication of percutaneous coronary interventions (PCI). There are no clear guidelines for IAD management, and limited data are available. Registry data and case series combined with extrapolations from our experience with spontaneous Type-A dissections suggest that very limited dissections are often managed conservatively with coronary stenting of the entry tear when possible, while more extensive dissections are managed surgically. We present a case report of a 50-year-old woman who underwent PCI for an ST-elevation myocardial infarction that resulted in an extensive IAD from the ostium of the right coronary artery to the aortic root, ascending aorta, and aortic arch. While the current evidence strongly supports surgical management of such extensive dissection, our patient was successfully managed conservatively with complete resolution according to short-term computed tomography imaging. This case suggests that conservative management may be a reasonable approach for select patients with extensive IAD.
医源性主动脉夹层(IAD)是经皮冠状动脉介入治疗(PCI)的一种罕见并发症。目前尚无关于IAD治疗的明确指南,且可用数据有限。登记数据、病例系列以及我们对自发性A型夹层的经验推断表明,对于非常有限的夹层,若可能,通常在入口撕裂处进行冠状动脉支架置入术,采取保守治疗;而对于范围更广的夹层,则采用手术治疗。我们报告一例50岁女性患者,她因ST段抬高型心肌梗死接受PCI治疗,结果导致从右冠状动脉开口至主动脉根部、升主动脉和主动脉弓出现广泛的IAD。虽然目前的证据强烈支持对如此广泛的夹层进行手术治疗,但根据短期计算机断层扫描成像,我们的患者通过保守治疗成功治愈,夹层完全消退。该病例表明,对于某些患有广泛IAD的患者,保守治疗可能是一种合理的方法。
