Both spontaneous superior mesenteric artery dissection (SMAD) and spontaneous renal artery dissection (SRAD) are very rare conditions. Their etiologies and natural histories are not precisely defined, but they are thought to be associated with underlying conditions. In this report, we describe an extremely rare case of SRAD in a man who had a history of spontaneous SMAD. We successfully treated SRAD with endovascular intervention. Isolated spontaneous SMAD and SRAD are both rare conditions. Their optimal treatment has not been established due to their rare entities, but endovascular treatment is a good option because it can prevent both advancement of infarction and renovascular hypertension, and it has become safer as device technology has improved. Patients with isolated visceral artery dissection should be carefully followed up.
自发性肠系膜上动脉夹层（SMAD）和自发性肾动脉夹层（SRAD）均为非常罕见的病症。它们的病因和自然病史尚未明确界定，但被认为与潜在病症相关。在本报告中，我们描述了一名有自发性SMAD病史的男性发生的极为罕见的SRAD病例。我们通过血管内介入成功治疗了SRAD。孤立性自发性SMAD和SRAD均属罕见病症。由于其罕见性，尚未确立其最佳治疗方法，但血管内治疗是一个不错的选择，因为它可以预防梗死进展和肾血管性高血压，并且随着设备技术的改进，其安全性也有所提高。孤立性内脏动脉夹层患者应予以密切随访。
