Spontaneous coronary artery dissection (SCAD) is an infrequent event that is most commonly associated with pregnant women or those in the postpartum period. Because of its rarity, the literature describing this condition is confined to sporadic case reports, with few reporting long-term follow-up, and no clear consensus exists on the optimal treatment strategy for these patients. The present article reports a single-centre experience with SCAD, highlighting the issues surrounding its management with a brief description of five cases of pregnancy-associated coronary dissection. The treatment used in these cases ranged from a conservative medical approach to surgical and percutaneous intervention, with one patient proceeding to transplantation. Four of the cases have long-term angiographic follow-up.In addition, a comprehensive review of all previously published cases is presented, and temporal trends in the management strategy are highlighted. Possible pathophysiological mechanisms pertaining to this condition, and the complex diagnostic and therapeutic issues involved, which may affect both patient and fetus, are discussed. Finally, an optimal approach to patients with SCAD, informed by our experience and literature review, is described.
自发性冠状动脉夹层(SCAD)是一种罕见事件,最常与孕妇或产后女性相关。由于其罕见性,描述这种病症的文献仅限于零星的病例报告,很少有报告长期随访情况,对于这些患者的最佳治疗策略也没有明确的共识。本文报告了单中心关于SCAD的经验,通过简要描述五例妊娠相关冠状动脉夹层病例,突出了围绕其管理的问题。这些病例所采用的治疗方法从保守药物治疗到手术和经皮介入不等,有一名患者接受了移植手术。其中四例进行了长期血管造影随访。此外,还对所有先前发表的病例进行了全面综述,并突出了管理策略的时间趋势。讨论了与这种病症相关的可能病理生理机制,以及所涉及的复杂诊断和治疗问题,这些问题可能会影响患者和胎儿。最后,根据我们的经验和文献综述,描述了针对SCAD患者的最佳治疗方法。
