Superior mesenteric artery (SMA) syndrome is a rare etiology of upper gastrointestinal obstruction. The measured angle between the SMA and the aorta is typically between 38 and 65° and maintained by mesenteric fat. Excessive fat loss can lead to intestinal obstruction due to an exaggerated acute angularity of the SMA, compressing the third part of the duodenum. We present a 22-year-old female with a history of aplastic anemia, status post bone-marrow transplant, who presented with intractable nausea and had confirmed SMA syndrome on CT angiography. Subsequently, the patient underwent nasogastric decompression and successful laparoscopic duodenojejunostomy.
肠系膜上动脉（SMA）综合征是上消化道梗阻的一种罕见病因。SMA与主动脉之间的测量角度通常在38°至65°之间，并由肠系膜脂肪维持。过度的脂肪丢失可导致SMA急性角度增大，压迫十二指肠第三部，从而引起肠梗阻。我们报告一例22岁女性，有再生障碍性贫血病史，骨髓移植术后，出现顽固性恶心，CT血管造影证实为SMA综合征。随后，该患者接受了鼻胃减压及成功的腹腔镜十二指肠空肠吻合术。
