Superior mesenteric artery (SMA) syndrome is a rare condition resulting in small bowel obstruction. The third part of the duodenum becomes compressed because of the narrow angle between the aorta and the SMA. Those at risk of developing SMA syndrome include patients who develop rapid weight loss, malignancy, eating disorders, burns, trauma and substance abuse. We present a case of a 73-year-old man that presented 5 days post a total hip replacement with abdominal pain and profuse bilious vomiting for 2 days. A computed tomography scan of his abdomen showed gross distension of his stomach with an abrupt occlusion of the duodenum at the level of the SMA which was consistent with SMA syndrome. The patient was treated conservatively and was later discharged from surgical services once his symptoms resolved and he was able to tolerate diet.
肠系膜上动脉（SMA）综合征是一种导致小肠梗阻的罕见病症。由于主动脉和肠系膜上动脉之间的夹角变窄，十二指肠第三部受到压迫。有患SMA综合征风险的人群包括体重迅速下降、患有恶性肿瘤、饮食失调、烧伤、创伤和药物滥用的患者。我们报告一例73岁男性病例，该患者在全髋关节置换术后5天出现腹痛和大量胆汁性呕吐2天。其腹部计算机断层扫描显示胃明显扩张，在肠系膜上动脉水平处十二指肠突然闭塞，这与SMA综合征相符。该患者接受了保守治疗，症状缓解且能够耐受饮食后，随后从外科出院。
