妊娠晚期急性A型主动脉夹层合并Neri C型右冠状动脉撕脱：病例报告
Acute type A aortic dissection with Neri type C avulsion of the right coronary artery in late pregnancy: a case report.
摘要(中文译文)
妊娠晚期急性Stanford A型主动脉夹层罕见但危及生命，右冠状动脉Neri C型撕脱进一步增加围手术期风险。本病例强调了早期识别和协调序贯管理的重要性。患者为24岁女性，妊娠38周3天，因突发胸背部疼痛就诊。超声心动图和主动脉磁共振成像证实急性Stanford A型主动脉夹层，疑累及分支血管。经多学科评估后，患者接受子宫下段剖宫产术及产科止血操作，随后行Sun手术、升主动脉置换术及右冠状动脉Neri C型撕脱的冠状动脉旁路移植术。母婴恢复良好，随访期间未见复发症状。妊娠晚期突发胸背部疼痛应警惕急性主动脉夹层，尤其当存在血管或超声心动图警示征象时。在此高危病例中，及时多学科序贯实施剖宫产、产科止血和主动脉修复对获得良好的母婴结局至关重要。
Abstract
Acute Stanford type A aortic dissection in late pregnancy is rare but life-threatening, and Neri type C avulsion of the right coronary artery further increases perioperative risk. This case highlights the importance of early recognition and coordinated sequential management. A 24-year-old woman at 38 weeks and 3 days of gestation presented with sudden chest and back pain. Echocardiography and aortic magnetic resonance imaging confirmed acute Stanford type A aortic dissection with suspected branch-vessel involvement. After multidisciplinary assessment, she underwent lower-segment cesarean delivery with obstetric hemostatic procedures, followed by Sun procedure, ascending aortic replacement, and coronary artery bypass grafting for Neri type C avulsion of the right coronary artery. The mother and infant recovered well, and no recurrent symptoms were observed during follow-up. In late pregnancy, sudden chest and back pain should prompt evaluation for acute aortic dissection, especially when vascular or echocardiographic warning signs are present. In this high-risk case, timely multidisciplinary sequencing of cesarean delivery, obstetric hemostasis, and aortic repair was critical to achieving favorable maternal and neonatal outcomes.
