Vascular Plug Embolization of a Superior Mesenteric Arteriovenous Fistula: Case Report and Literature Review of Endovascular Treatment.

Introduction: Arteriovenous fistula (AVF) rarely occurs in the portal venous system. Aetiologies include iatrogenic, surgical, and penetrating trauma of the abdomen. Clinical manifestations of superior mesenteric portal arteriovenous fistula (SMPAVF) are right heart failure, mesenteric ischaemia, or signs of portal hypertension.

Fusion imaging for pulmonary artery embolization: impact on fluoroscopy duration and contrast agent exposure.

Objectives: To assess the impact of fusion imaging guidance on fluoroscopy duration and volume of contrast agent used for pulmonary artery embolization.

Methods: Thirty-four consecutive patients who underwent pulmonary artery embolization for pulmonary arterio-venous malformation ( = 28) or hemoptysis ( = 6) were retrospectively included. In the experimental group ( = 15), patients were treated using fusion imaging with 2D/3D registration.
