《急診每日一題》近端十二指腸梗阻原因之一2021年2月
Question?問題:
Superior mesenteric artery syndrome is a cause of proximal intestinal obstruction. What causes SMAS??
腸系膜上動脈綜合癥(SMAS)是導致近端腸梗阻的一個原因。SMAS是如何發(fā)生的?

?Answer?答案:
SMAS results from compression of the third portion of the duodenum between the SMA and abdominal aorta due to narrowing of the space between these two structures, primarily due to loss of the intervening mesenteric fat pad。
SMAS是由于腸系膜上動脈和腹主動脈間隙狹窄對這兩個結構之間的第三段十二指腸造成壓迫。(此間隙狹窄)主要原因是缺乏腸系膜脂肪墊。
