Thoracic aortic dissection is a life-threatening emergency that can be easily overlooked in the absence of commonly associated risk factors, such as hypertension, connective tissue disease, cocaine use, and older age. The classic presenting symptom of abrupt-onset, severe "tearing" or "ripping" chest pain may be an unreliable finding. We present the case of a 30-year-old previously healthy male with no known risk factors who turned around to sanitize after having a bowel movement when he began feeling tight, severe back pain. After ruling out common etiologies of acute back pain with a negative computed tomography (CT) scan, point-of-care ultrasonography was performed which revealed a crescent-shaped flap within the abdominal aorta. Follow-up computed tomography angiogram (CTA) confirmed an extensive Stanford type A aortic dissection. Remarkably, the patient remained hemodynamically stable throughout his emergency department (ED) visit without developing any new pulse deficits or heart murmurs. It is a good reminder to maintain a high index of suspicion for aortic dissection in patients presenting with acute back pain without any classic risk factors. We also review the most recent literature regarding aortic dissection in young adults and ultrasonography for aiding diagnosis in the ED.

胸主动脉夹层是一种危及生命的急症,在没有高血压、结缔组织病、使用可卡因及高龄等常见相关危险因素的情况下,很容易被忽视。典型的突发、严重“撕裂样”或“刀割样”胸痛症状可能并不可靠。我们报告一例30岁既往健康、无已知危险因素的男性病例,该患者在排便后转身准备清洁时开始感到胸部紧绷、剧痛。在计算机断层扫描(CT)扫描结果为阴性从而排除急性背痛的常见病因后,进行了床旁超声检查,结果显示腹主动脉内有一个新月形瓣片。后续的计算机断层血管造影(CTA)证实为广泛的斯坦福A型主动脉夹层。值得注意的是,该患者在急诊室就诊期间血流动力学一直保持稳定,未出现任何新的脉搏缺失或心脏杂音。这很好地提醒我们,对于没有任何典型危险因素而出现急性背痛的患者,要高度怀疑主动脉夹层。我们还回顾了有关年轻成人主动脉夹层及急诊室辅助诊断超声检查的最新文献。
