Superior mesenteric artery (SMA) syndrome is caused by compression of the transverse duodenum at the angle between the aorta and the SMA that may lead to postprandial or constant epigastric pain, nausea, vomiting anorexia and weight loss. The diagnosis is often missed given nonspecific symptoms and low reported prevalence. The authors present a case of a 29-year-old female who presented with seven months of epigastric pain and significant weight loss. The patient was diagnosed with SMA syndrome with the aid of upper endoscopy, upper gastrointestinal barium study and computed tomography imaging.
肠系膜上动脉（SMA）综合征是由于十二指肠横部在主动脉与肠系膜上动脉夹角处受压所致，可导致餐后或持续性上腹部疼痛、恶心、呕吐、厌食及体重减轻。鉴于症状不具特异性且报道的患病率较低，该综合征的诊断常常被漏诊。作者报告了一例29岁女性患者，该患者出现上腹部疼痛7个月且体重显著减轻。借助上消化道内镜检查、上消化道钡餐造影及计算机断层扫描成像，该患者被诊断为肠系膜上动脉综合征。
