Superior mesenteric artery (SMA) syndrome: an unusual cause of intestinal obstruction in palliative care

Superior mesenteric artery (SMA) syndrome is an uncommon cause of intestinal obstruction and seldom been mentioned in palliative care. Hereby, we reported a case of SMA syndrome who presented with symptoms of upper intestinal obstruction in a 68-year-old patient; subsequent CT findings were classical of SMA syndrome. The patient's history of poliomyelitis and recent significant weight loss were the predisposing factors for SMA syndrome. It also highlights the importance of monitoring signs and symptoms of intestinal obstruction in such patients before considering switching to oral feeding.
