Superior mesenteric arteriovenous fistulae (SMAVF) are a rare complication from trauma or iatrogenic surgical intervention. There are less than 50 cases reported in the literature and no clear guidelines as to the best practices for diagnosis and treatment. SMAVF are often asymptomatic but can present with nonspecific abdominal symptoms ranging from nausea and vomiting to gastrointestinal bleeding and mesenteric ischemia. Symptom onset, when present, is often delayed years after the inciting event, further complicating the diagnosis. We present a case of a 71-year-old man presenting with mesenteric ischemic symptoms secondary to a large SMAVF that was successfully treated with coil embolization. We describe our approach to treatment and describe the classical imaging findings. We, then, review the current literature and management recommendations.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
