Endoleak is still an unsolved problem associated with endovascular repair of aortic aneurysms. Percutaneous treatment of type II endoleaks after endovascular repair of abdominal or thoracic aneurysms is feasible and effective. Although there is only very limited data available, this technique appears to be at least as effective as the endovascular approach. As this is a straight forward procedure, which is much less time consuming when compared with the endovascular approach, the indication for using this technique may expand in the future.
