Role of three-dimensional multidetector computed tomography for a huge superior mesenteric artery
The determination of vasorelaxant activity was performed in superior mesenteric artery
rings with or without functional endothelium pre-contracted to the same tension (approximately 8.
This in turn increases the aortomesenteric angle and relieves the extrinsic compression of the superior mesenteric artery
on the underlying duodenum.
Traumatic injury of the proximal superior mesenteric artery
A possible new ancillary sign for diagnosing midgut volvulus: The truncated superior mesenteric artery
Nutcracker syndrome refers to the compression of the left renal vein between the aorta and the superior mesenteric artery
, which results in elevated left renal vein pressure and possible collateral vein development.
The duodenum may also lie in an abnormal position, anterior to the superior mesenteric artery
1,3) The etiology of left predominance in idiopathic cases has been postulated to be stretching of the renal vein over the aorta and compression between the superior mesenteric artery
(SMA) and the aorta, known as the nutcracker phenomenon.
The superior mesenteric artery
was seen crossing the transverse portion of the duodenum, though resultant ileus was not seen.
Incidental note was also made of double inferior vena cavae (Figures 1 and 3) and transposition of the superior mesenteric artery
and superior mesenteric vein axis with associated intestinal malrotation.
CT can show prevertebral extension of tumor across the midline as well as encasement of the celiac axis or superior mesenteric artery
by the neuroblastoma.
