The superior mesenteric artery syndrome is an uncommon entity included in the spectrum of vascular syndromes. low presentation, variety specific symptoms and shortage bibliography presents a challenging diagnosis for both clinicians radiologists.

Mesenteric ischemic symptoms appear only when two of the three major splanchnic arteries from the abdominal aorta are involved. Recently, we encountered a case of chronic mesenteric ischemia in a 50-year-old female patient caused by atherosclerotic obstruction of the celiac trunk and superior mesenteric artery. She was treated with a retrograde bypass graft from the right common iliac artery to...

We studied the effect of endothelium on the flow-induced response of conductance arteries and the resistance arteriolar network in an in situ model of perfused mesenteric artery in normotensive Wistar-Kyoto and spontaneously hypertensive rats. The mesenteric network was perfused with a Tyrode's albumin solution. The diameter of a conductance mesenteric artery was measured using a video camera s...

Chronic mesenteric ischaemia is a rare and potentially fatal condition most commonly due to atherosclerotic stenosis or occlusion of two or more mesenteric arteries. Multivessel revascularisation of both primary mesenteric vessels, the celiac artery and superior mesenteric artery (SMA), is the current mainstay of treatment; however, in a certain cohort of patients, revascularisation one or both...

SUPERIOR MESENTERIC ARTERY SYNDROME AN UNUSUAL CAUSE OF DUODENAL OBSTRUCTION. (Abstract): Superior mesenteric artery (SMA) arising from aorta at the level of first lumbar vertebra usually takes an angular downward course from ventral surface of aorta. It is through this vascular angle that the 3rd part of duodenum passes at the level of 4th lumbar vertebra. Fat and lymphatics around SMA maintai...

hepatic artery aneurysms are rare but potentially life threatening. we describe a novel case of a successful endovascular coil embolization of a huge hepatic artery aneurysm. a 67-year-old woman presented with recent abdominal pain that had begun from 2 weeks before referring to our hospital. sonographic and computerized tomographic (ct) findings revealed a huge hepatic artery aneurysm with 95 ...

This study was designed to determine if the differential effect of high fat and high carbohydrate meals on mesenteric blood flow is a result of changed gastric emptying rate. Eight healthy men were studied twice. Superior mesenteric artery blood flow (Doppler ultrasound) was measured before and after a 2.5 MJ meal (either 74% of the energy as carbohydrate or 71% as fat). Emptying of meals was f...

AIMS Microdomain signalling mechanisms underlie key aspects of artery function and the modulation of intracellular calcium, with transient receptor potential (TRP) channels playing an integral role. This study determines the distribution and role of TRP canonical type 3 (C3) channels in the control of endothelium-derived hyperpolarization (EDH)-mediated vasodilator tone in rat mesenteric artery...

Renal vasculatures variations was normally found. Awareness of these variation was useful in many clinical fields procedures. During the routine dissection of posterior abdominal wall of approximately a 67 year old male formaldehyde cadaver. The left kidney present with arterial variation. An accessory renal artery was detected arising from the lateral aspect of the abdominal aorta at level dis...
