2024年7月20日 · Superior mesenteric artery (SMA) syndrome, also known as Wilkie syndrome, cast syndrome or aortomesenteric duodenal compression syndrome, is a rare acquired vascular compression disorder in which acute angulation of the superior mesenteric artery (SMA) results in compression of the third part of the duodenum, leading to obstruction.

2020年1月2日 · This examination includes evaluation of the abdominal aorta and the celiac, superior mesenteric (SMA), and inferior mesenteric (IMA) arteries. Doppler ultrasonography can accurately assess anatomic…

2021年11月15日 · Superior mesenteric artery stenosis refers to any form of narrowing involving the superior mesenteric artery and may result from a number of factors. It can result in acute or chronic mesenteric ischemia. Several values on doppler ultrasound have been proposed that include: From a different paper: 1.

SMA （shape memory alloy）即记忆合金，具有形状记忆效应（shape memory effect），是目前 形状记忆材料 中形状记忆性能最好的。该种合金的形状被改变后，一旦受热到一定的跃变温度，便又可以恢复到最初形态。

2005年3月14日 · Superior mesenteric artery (SMA) syndrome (or aorto-mesenteric compass syndrome or Wilkie's disease) is a relatively rare condition caused by a short Treitz's ligament, or by an unusually low origin of the SMA causing a reduction of …

2024年12月19日 · The superior mesenteric artery (SMA) is one of the three non-paired major splanchnic arteries in the abdominal cavity arising from the abdominal aorta and supplying the midgut; i.e. from mid duodenum to distal transverse colon.

Ultrasound – Mesenteric Artery Protocol. PURPOSE: To determine the absence or presence of stenosis or aneurysm of the central visceral arteries.
