Type 1 endoleaks following endovascular aortic aneurysm repair are associated with poor outcomes and re-intervention is recommended as soon as possible after diagnosis. When standard endovascular or surgical treatment options are unsuitable due to severe co-morbidity or adverse anatomic factors, patients can be treated by transcatheter embolisation of the endoleak itself. We describe six such patients with proximal and distal type 1 endoleaks, who have been successfully treated by transcatheter embolisation with Onyx. The embolisation technique, advantages of using this relatively novel liquid embolic agent and potential pitfalls are discussed.
