Superior mesenteric artery dissection with prolonged abdominal angina treated by laparotomy, endarterectomy, patch angioplasty, and retrograde open mesenteric stenting: a case report.

BACKGROUND

Most patients with isolated superior mesenteric artery (SMA) dissection are successfully managed conservatively. However, some patients require more invasive treatment.

CASE PRESENTATION: We herein describe a 45-year-old man with isolated SMA dissection. He initially underwent conservative treatment. However, because of persistent abdominal angina, we considered the need for surgical revascularization. He was successfully treated by endarterectomy, patch angioplasty, and retrograde open mesenteric stenting. The abdominal angina was stabilized thereafter.

CONCLUSIONS

The combination of endarterectomy, patch angioplasty, and retrograde open mesenteric stenting is useful for isolated SMA dissection, and long patency can be expected for some patients.
