Superior mesenteric artery syndrome: A rare case of bowel obstruction in schizophrenic patient

Introduction: superior mesenteric artery syndrome is a rare condition of obstruction to the third part of duodenum. Identification of this syndrome is challenging and is frequently made by a process of exclusion. case report: We report the first case of superior mesenteric artery syndrome in a severely cachectic schizophrenic patient with paranoid delusions who presented with features of proximal gastrointestinal obstruction. the diagnosis was not straightforward and was supported by radiologic evidence of obstruction. the patient was treated conservatively with nasogastric tube decompression, fluid and electrolyte correction and enteral nutrition via nasojejunal tube. However, the patient was not cooperative with treatment and subsequently demised. conclusion: this report aims to strengthen the awareness of this condition to prevent delay in diagnosis and treatment of this life-threatening condition.
