Spontaneous infrarenal abdominal aortic dissection (SIAAD) is rare. Patients with SIAAD may be asymptomatic or may present with abdominal pain or lower extremity ischemia. We describe a case report of a patient with SIAAD who presented with claudication. We reviewed the English literature on this disorder and specifically evaluated the differences between patients on the basis of their presenting symptoms. Patients who had SIAAD and lower extremity ischemia were more likely to have the dissection process extend into the iliac or femoral artery and were less likely to have an associated abdominal aortic aneurysm. Aortic rupture in the presence of SIAAD was associated with increased risk of death.
自发性肾下腹主动脉夹层（SIAAD）较为罕见。SIAAD患者可能无症状，或表现为腹痛或下肢缺血。我们报告一例表现为间歇性跛行的SIAAD患者。我们回顾了关于该疾病的英文文献，并特别根据患者的症状表现评估了差异。患有SIAAD且有下肢缺血的患者，夹层过程更有可能延伸至髂动脉或股动脉，且合并腹主动脉瘤的可能性较小。SIAAD患者发生主动脉破裂与死亡风险增加相关。
