Superior Mesenteric Artery Syndrome in a Young Male: A Rare Case Report

Introduction: Superior mesenteric artery (SMA) syndrome is a rare acquired disorder in which acute angulation of SMA causes compression of the third part of the duodenum between the SMA and the aorta, leading to obstruction. Case report: A 18-year-old male patient presented to PDU Civil hospital Rajkot with complaints of abdominal pain, nausea and occasional vomiting since 7 days. The vomiting was aggravated after each meal. Patient was managed conservatively initially, surgical intervention done after failure of response to conservative management. Patient posted for surgery and undergone Laparoscopic Duodenojejunostomy after 5 days of conservative management. Discussion: The Superior Mesenteric Artery usually forms an angle of approx.45?with the abdominal aorta at its origin, while the third part of the duodenum crosses in between the SMA anteriorly and aorta posteriorly. Any factor that sharply narrows this aortomesentric angle (to less than 25?approx.) can cause entrapment and compression of the third part of the duodenum as it passes between the SMA and aorta, resulting in the Superior Mesenteric Artery Syndrome. Conclusion: This case describes an SMA syndrome presenting in a young adolescent male with no any surgical history or history of weight loss but represented with complains of upper GI Obstruction representing a rare, but important differential for upper gastrointestinal obstruction.
