Superior mesenteric artery aneurysms are a rare clinical finding but can present with a wide range of symptoms. They are associated with a high risk of rupture, as well as high morbidity and mortality. We present a case of a 38-year-old female who presented with acute abdominal pain and a pulsatile palpable mass in the right epigastric region without other signs or symptoms.

We report a case of nonocclusive mesenteric ischemia (NOMI), which developed after grafting for a descending thoracic aortic aneurysm in a hemodialysis patient. On postoperative day 5, acute increases in serum enzyme levels developed. Emergency angiography revealed severe vasoconstriction in the superior mesenteric artery (SMA) and other splanchnic arteries. Therefore an infusion of papaverine ...

Spontaneous visceral artery dissection is an uncommon event with an unpredictable natural history with superior mesenteric artery being the most common affected artery. It is most often asymptomatic and usually diagnosed at autopsy. Pre-disposing factors are not specific but have been suggested to be pre-existing vascular disease, hypertension and pregnancy. Spontaneous resolution, definitive o...

A 60-year-old man who 10 years earlier underwent replacement of a thoracoabdominal type B dissecting aortic aneurysm with a Dacron graft, was admitted for an 8 cm pseudoaneurysm involving the coeliac axis, the superior mesenteric artery (SMA) and the right renal artery, and a 3 cm pseudoaneurysm involving the left iliac arteries (Fig. 1). During the primary procedure, the coeliac axis, the SMA ...

Bacterial endocarditis may give rise to mycotic arterial aneurysms in any part of the body, but particularly in the thoracic aorta, intracranial vessels, superior mesenteric artery, and the large arteries to the extremities (Weintraub and Abrams, I968). Aneurysms occurring in the coronary arteries are commonly arteriosclerotic or congenital and are very rarely mycotic in origin (Daoud et al., I...
