title: Superior mesenteric vein thrombosis accompanied with severe appendicitis.
abstract: Superior mesenteric vein (SMV) thrombosis caused by acute appendicitis is a very rare entity nowadays. We report a successfully treated case of a 21-year-old man with SMV thrombosis associated with severe acute appendicitis. Intravenous heparin was administered, and it was later substituted with warfarin. Systemic antibiotic therapy was continued for 1 week, and it was substituted with oral antibiotics, which were administered for 3 weeks. On the 45th postoperative day, follow-up computed tomography scan demonstrated dissolution of SMV thrombosis. Anticoagulation therapy was maintained for 3 months. He was discharged without any complications. SMV thrombosis can be treated successfully with emergency appendectomy, broad-spectrum antibiotics, and anticoagulation therapy.
