Superior mesenteric artery (SMA) syndrome is a gastro-vascular disorder in which the third and final portion of the duodenum is compressed between the abdominal aorta (AA) and the overlying superior mesenteric artery. This rare, potentially life-threatening syndrome is typically caused by an angle of 6–25° between the AA and the SMA, in ...
The management of isolated superior mesenteric artery dissection (ISMAD) often involves conservative treatment, which includes blood pressure lowering therapy, analgesics, and initial bowel rest. [4] Periodic follow-ups with CT angiography are a part of the conservative treatment approach. Over time, many patients show improvement or no change ...
In addition, stenosis of the inferior mesenteric artery was very severe. Abdominal angina is caused by obstruction or stenosis of the inferior mesenteric artery (IMA), celiac trunk, or superior mesenteric artery (SMA). [4] More than 95% of abdominal angina is caused by stenosis of the splanchnic arteries due to local atherosclerosis.
In embolic acute intestinal ischemia, CT-Angiography can be of great value for diagnosis and treatment. It may reveal the emboli itself lodged in the superior mesenteric artery, as well as the presence or absence of distal mesenteric branches. [18] Late findings, which indicate dead bowel, include: Intramural bowel gas [29] Portal venous gas
The nutcracker syndrome results from compression of the left renal vein between the aorta and the superior mesenteric artery. The nutcracker syndrome ( NCS ) results most commonly from the compression of the left renal vein (LRV) between the abdominal aorta (AA) and superior mesenteric artery (SMA), although other variants exist.
In human anatomy, the superior mesenteric artery (SMA) is an artery which arises from the anterior surface of the abdominal aorta, just inferior to the origin of the celiac trunk, and supplies blood to the intestine from the lower part of the duodenum through two-thirds of the transverse colon, as well as the pancreas.
Primary vascular causes of bowel infarction, also known as mesenteric ischemia, are due to blockages in the arteries or veins that supply the bowel.Types of mesenteric ischemia are generally separated into acute and chronic processes, because this helps determine treatment and prognosis.
The remaining ileum, which is of varying length, survives on a single mesenteric artery, which it is twisted around in a spiral form. [1] The term apple-peel intestinal atresia is generally reserved for when it affects the jejunum, [ 10 ] [ 11 ] while Christmas tree intestinal atresia is used if it affects the duodenum.
