This is a case report of a 30-year-old female patient with a splenic arteriovenous fistula of rare, atypical clinical course. The patient was admitted to the hospital due to strong abdominal pains and fever. 13 years earlier, the patient underwent splenectomy due to post-traumatic rupture of the spleen. On imaging examinations prior to surgery (ultrasonography, CT), a splenic arteriovenous fistula was diagnosed. The patient was operated on due to increasing abdominal pain. The fistula was closed by splenic artery and splenic vein banding during the course of laparotomy. This case report will be discussed based on literature review.
