Abstract
This is a case report of acute superior mesenteric vein (SMV) thrombosis in a 24-year-old male with history of underlying psychiatric symptoms who had no traditional risk factors. The patient presented with abdominal pain, fever, and constipation. The patient's worsening symptoms led to an eventual diagnosis via computed tomography (CT) imaging. Management included anticoagulation therapy and multidisciplinary care. This case highlights the importance of considering SMV thrombosis in young adults and suggests a potential link between psychiatric conditions and thrombotic events, as evidenced by this patient's psychiatric history.
