The “elephant trunk” technique made easier

In patients with diffuse aneurysmal disease, the “elephant trunk” technique, which uses surplus intravascular graft length to facilitate subsequent operations on the downstream aorta, is an accepted method of treatment. Nevertheless, in the presence of large aneurysms without a definite neck beyond the left subclavian artery, there is an increased risk of rupture at the level of the distal anastomosis. My colleagues and I herein describe a modified elephant trunk technique performed with a new prosthesis, which was conceived to overcome the difficulties and the risks inherent in a large aneurysmal neck.
