A 24‑year‑old male was brought to emergency department with blunt trauma abdomen. Ultrasound of the abdomen showed gross hemoperitoneum and splenic injury. Emergency laparotomy was done in view of hemodynamic instability and splenectomy was performed. Postoperatively patient had persistent vomiting. Upper gastrointestinal endoscopy revealed external compression of duodenum. Contrast‑enhanced CT of the abdomen revealed acute angulation of superior mesenteric artery from aorta causing compression of third part of duodenum–diagnostic of superior mesenteric artery syndrome. Duodenojejunostomy was performed due to failure of conservative management. Postoperative period was uneventful and is on regular follow up.
