A Novel Approach for Treating Type 2 Endoleaks Utilizing Contrast-Enhanced Ultrasound

Abstract Endoleaks are a frequent and well-known complication following endovascular repair of aortic aneurysms. An endoleaks can lead to increased intra sac pressure, sac enlargement and potential aneurysm rupture. Type 2 endoleaks result from retrograde filling of aortic branch vessels and can be treated with surgical, endovascular or direct percutaneous approaches. Direct percutaneous treatment typically involves embolization of the perfused endoleak cavity typically using a translumbar approach with fluoroscopic guidance. We illustrate a novel image-guided approach for percutaneous transabdominal endoleak treatment utilizing contrast-enhanced ultrasound in combination with fluoroscopy.
