a 48-year-old male patient presented to the emergency department with the complaints of epigastric pain and melena for the past 3 days. the pain was started suddenly and has progressed and after a while, he passed melena stool. he also mentioned some episodes of vomiting that was not bloody. the pain score was about 8/10 (based on verbal quantitative scale) and slightly radiated to back. he loo...

Spontaneous dissection of the superior mesenteric artery (SMA) is a rare condition. Here we report 2 cases of spontaneous SMA dissection causing acute abdomen. Bowel infarction did not occur in either case despite total occlusion or severe stenosis of the SMA;we successfully managed isolated SMA dissection without surgical intervention. Our nonoperative management regimen for spontaneous SMA di...

Superior mesenteric artery (SMA) dissection without aortic dissection is a rare condition, and its diagnosis is considered to be difficult. Intestinal infarction is a severe complication of the disease, which may require resection of the intestine. We present a case of isolated SMA dissection. A 53-year-old man experienced sudden pain in the abdomen while playing Japanese pinball and was admitt...

A Stanford Type A aortic dissection is a life-threatening surgical emergency that requires emergent surgery. The mortality after repair is high especially if the aortic dissection is complicated by visceral or peripheral malperfusion. We describe a case of a male patient who presented with an aortic dissection involving the ascending aorta, aortic arch, descending thoracic aorta, and the abdomi...

Spontaneous superior mesenteric artery (SMA) dissection is a rare, but potentially fatal disease. Prompt diagnosis and treatment of SMA dissections result in a lower prevalence of intestinal infarction and mortality. In the current era, imaging techniques can promptly diagnose SMA dissection; however, no definitive guidelines have been established to treat this condition.

OBJECTIVES To analyze computed tomography (CT) imaging features of isolated dissection of the superior mesenteric artery (SMA). METHODS The imaging findings of 20 consecutive patients with isolated dissection of the SMA were retrospectively evaluated and categorized according to a new imaging classification: Type A, dissections localized at the curved part of the SMA and extended proximally; ...

A 50-year-old man had a mesenteric ischemia related to superior mesenteric artery (SMA) occlusion associated with a type B aortic dissection. We decided to perform stent placement for the SMA and could avoid mesenteric ischemia. We think the stent placement in the SMA might be an option for the treatment of mesenteric ischemia caused by aortic dissection.

Introduction. Isolated superior mesenteric artery (SMA) dissection, without associated aortic dissection, is relatively uncommon. Therefore, there are insufficient data to support a particular therapeutic option in the specific setting of isolated SMA dissection associated with thrombotic complications. Case report. In this article we describe the diagnosis and treatment of a patient who presen...

OBJECTIVE Isolated spontaneous dissection of the superior mesenteric artery (SMA) is very rare among of the visceral artery dissection and its treatment is not established. In this paper we present our experiences and consider the treatment of isolated SMA dissection. METHODS A retrospective review of our cases from 2005 was performed. Clinical symptoms, radiologic findings and results were e...

We report the case of a 49-year-old man admitted to our Institute because he suffered acute abdominal pain induced by eating. Sonography don't revealed pathological findings. Then underwent a multi-detector row computed tomography angiography (MDCTA) that revealed an intimal flap separating true and false lumens that was located 2 cm from the origin of the superior mesenteric artery (SMA) and w...
