Research Abstract

We investigated the usefulness of aneurysmal embolization using liquid material and balloon-expandable stent. First, we studied the safety of liquid material consisted of ethylene vinyl alcohol and ethanol. Then, it was proved that the liquid material was very safe and easy to use. Using the animal model of the side-wall aneurysm, aneurysmal embolization using liquid material and balloon-expandable stent. Then, it was proved that the embolization we used was safe and useful, however, some small infraction was seen.
