Abstract
Background: Isolated spontaneous dissection of the superior mesenteric artery is rare. We encountered this rare entity and successfully treated it by endovascular stent placement. Methods: The patient was a 48-year-old man and he developed sudden abdominal pain. Contrast-enhanced computed tomography revealed dissection of the superior mesenteric artery and the true lumen was compressed by the partially thrombosed false lumen. Two PALMAZTM stents (7 × 20 mm and 8 × 20 mm) were deployed in the true lumen through a transfemoral approach. Results: Blood flow to the distal branches improved significantly after stent deployment. Immediately after the procedure he became asymptomatic and was discharged 9 days after the procedure. One year later, the superior mesenteric artery was shown to be patent by contrast-enhanced computed tomography. Conclusion: Endovascular therapy is a good option for anatomically feasible cases of isolated spontaneous dissection of the superior mesenteric artery.
