Traumatic Isolated SMA Dissecting Aneurysm Associated with Burst Fractures of Lumbar Spines

ABSTRACT

Isolated dissecting aneurysm of the superior mesenteric artery (SMA) is a rare condition. Although aneurysms of the SMA are frequently classified with other splanchnic aneurysms, dissecting SMA aneurysms are quite different in terms of their etiology and natural history. Therefore, independent consideration is warranted during their treatment. In this case report, a dissecting aneurysm was accompanied by burst fractures of the first and third lumbar spines at the same height. We treated the patient, who was suffering from chronic post-prandial intermittent abdominal pain after falling down. The patient stopped displaying repeated episodes of abdominal pain did not recur after the false lumen entry was closed by a short exclusion stent graft, and there were no procedural complications. The stent graft remained patent, and the patient has remained free of symptoms during the 16 months follow-up period. We present here the case of a traumatic isolated SMA dissecting aneurysm that was successfully managed by endovascular treatment.
