肠系膜上动脉压迫综合征——不能忽视的消瘦病因

Superior mesenteric artery syndrome:a nonnegligible cause of emaciation

消瘦是内分泌与代谢病专业临床诊疗中经常遇到的一种症状,肠系膜上动脉压迫综合征(SMAS)是其重要原因之一,但常被内分泌科医生忽略。SMAS可由极端体重下降引起,同时又会致后者进一步加重,两者形成恶性循环导致难于纠正的消瘦。其治疗手段有胃肠减压、肠内或肠外营养等,部分危重症患者需要手术解除梗阻以达治疗效果。

Emaciation is a symptom encountered frequently in clinical diagnosis and treatment of endocrine and metabolic diseases,and superior mesenteric artery syndrome(SMAS) is one of the major causes.But SMAS is often overlooked by endocrinologists.SMAS can be caused by extreme weight loss,which can further aggravate weight loss at the same time,and the two form a vicious circle that leads to difficult-to-correct emaciation.The treatment includes gastrointestinal decompression,enteral or parenteral nutrition,etc.Some critically ill patients require surgical relief of the obstruction to achieve therapeutic effect.
