A 77-year-old woman was admitted to our hospital with a complaint of abdominal pain. The image examination confirmed sigmoid volvulus. We performed endoscopic detorsion. A few days later, she developed abdominal pain again. We performed contrast computed tomography (CT) scan, which showed the inferior mesenteric veins thrombosis. After the diagnosis, heparin was started. The abdominal pain gradually diminished, and edoxaban was administered orally. On day 16, she was discharged from the hospital because there was no exacerbation of symptoms after the cessation of heparin. On day 60, contrast CT scan showed that the thrombus in the inferior mesenteric veins disappeared. The inferior mesenteric veins thrombosis might be associated with blood flow disturbance due to sigmoid volvulus. The present case is the first reported case of the inferior mesenteric veins thrombosis associated with sigmoid volvulus. The inferior mesenteric veins thrombosis could be one of the differential diagnoses in abdominal pain after endoscopic detorsion.
