It is caused by a narrow angle between the aorta and the superior mesenteric artery, resulting in the clamping of the third portion of the duodenum. It is more common in females (2:1), with no racial differences. It is also more frequent in patients under 30\u2005years and may have a congenital or acquired aetiology. There is only one case of the familial form described in the medical literature. We present a case of a 20-year-old woman, with recurrent episodes of epigastric discomfort and vomiting since she was 10\u2005years old. After clinical suspicion, diagnosis was achieved after digestive endoscopy, upper gastrointestinal transit and abdominal MR. The patient was kept under parenteral nutrition for 17\u2005days before surgery. She was discharged 8\u2005days after surgery and the postoperative course was uneventful.<\/jats:p>","DOI":"10.1136\/bcr-2016-214784","type":"journal-article","created":{"date-parts":[[2016,4,28]],"date-time":"2016-04-28T17:10:43Z","timestamp":1461863443000},"page":"bcr2016214784","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":5,"title":["Familial superior mesenteric artery syndrome"],"prefix":"10.1136","volume":"2016","author":[{"given":"Ana Raquel","family":"Martins","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jos\u00e9 Filipe","family":"Cunha","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joana","family":"Patr\u00edcio","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jorge","family":"Caravana","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[2016,4,28]]},"reference":[{"key":"2025042703185664000_2016.apr28_1.bcr2016214784.1","doi-asserted-by":"publisher","DOI":"10.1007\/s11606-005-0237-7"},{"key":"2025042703185664000_2016.apr28_1.bcr2016214784.2","unstructured":"Supriya G , Saritha S , Kuma P .
