Successful transcatheter embolization of a superior mesenteric arteriovenous fistula: Comprehensive imaging assessment and 3-year follow-up

Abstract

Superior mesenteric arteriovenous fistulas (SMAVFs) are uncommon vascular anomalies. Advances in vascular interventional radiology have introduced transcatheter embolization as a safe and effective minimal invasive treatment option of SMAVFs. We report a successful case of transarterial coil embolization of an iatrogenic SMAVF in a 24 year old patient. We illustrate relevant imaging findings from different imaging modalities that were used for assessment of the fistula and evaluation of the treatment outcome. In addition, we report the post-procedural clinical outcome after three year follow-up.
