Superior mesenteric artery (SMA) syndrome is a rare cause of small bowel obstruction (SBO) resulting from compression of the duodenum by the SMA. Patients at risk of developing SMA syndrome include those who have experienced rapid weight loss from chronic illnesses, malignancy, bariatric surgery, eating disorders, burns, trauma, or substance abuse. We present the case of a 54-year-old cachectic female patient who presented with sudden onset nausea, vomiting, and severe epigastric pain. Imaging studies revealed distention of the stomach and proximal portion of the duodenum with abrupt narrowing of the third part of the duodenum consistent with SMA syndrome. A laparoscopy confirmed the diagnosis and duodenojejunostomy resulted in resolution of the symptoms.
肠系膜上动脉（SMA）综合征是小肠梗阻（SBO）的一种罕见病因，由肠系膜上动脉压迫十二指肠所致。有患SMA综合征风险的患者包括那些因慢性疾病、恶性肿瘤、减肥手术、饮食失调、烧伤、创伤或药物滥用而体重迅速下降的人。我们报告一例54岁恶病质女性患者，该患者突然出现恶心、呕吐和严重上腹部疼痛。影像学检查显示胃和十二指肠近端扩张，十二指肠第三部突然变窄，符合SMA综合征。腹腔镜检查确诊了该诊断，十二指肠空肠吻合术使症状得到缓解。
