Spontaneous isolated visceral artery dissection is rarely encountered. Endovascular intervention with good outcomes has become popular for patients with persistent symptoms or developing ischemia. We could perform life-saving treatment for a spontaneous isolated superior mesenteric artery dissection with a unique endovascular intervention. We describe the case of an 80-year-old man who presented with acute abdominal pain and a spontaneous isolated superior mesenteric artery dissection measuring 35 mm in major diameter and 6.6 mm in minor diameter on abdominal contrast-enhanced computed tomography. After admission, abdominal pain was progressive, and a repeated scan revealed progression of the dissection. As an endovascular intervention, via the bilateral femoral approach, detachable coils were placed in the false lumen of the superior mesenteric artery dissection through the false lumen under the micro-balloon occlusion at the point of re-entry and entry through the true lumen to prevent coil migration. Technical and clinical success was achieved without serious adverse events. Coil embolization using micro-balloon assistance combined with the double-catheter technique for a large entry and re-entry false lumen of a spontaneous isolated superior mesenteric artery dissection was useful and feasible.

自发性肠系膜上动脉自发剥离假管腔缠绕的新技术

自发性内脏动脉解剖很少见。具有持续结果或局部缺血的患者已普遍接受具有良好结果的血管内干预。通过独特的血管内介入治疗，我们可以对自发性肠系膜上动脉自发分离进行挽救生命的治疗。我们描述了一个病例，该病例在腹部对比增强型计算机断层扫描中表现为急性腹痛和自发性孤立的肠系膜上动脉分离，其长径为35 mm，短径为6.6 mm。入院后，腹痛是进行性的，并且重复扫描显示了解剖的进展。作为一种血管内干预，通过双侧股骨入路，将可分离的线圈放置在肠系膜上动脉解剖的假腔中，穿过假性腔再进入微气球闭塞处，然后再进入并通过真腔进入，以防止线圈迁移。在没有严重不良事件的情况下取得了技术和临床成功。使用微气球辅助结合双导管技术对自发性孤立的肠系膜上动脉夹层进行大的进入和再进入假管腔的栓塞术是有用且可行的。
