Concomitant Coil Embolization for Gutter Leak during Endovascular Aortic Repair with the Snorkel Technique.

Snorkel endovascular aortic repair (SEVAR) is reported to be effective for the treatment of pararenal or juxtarenal aortic aneurysms. SEVAR can be performed with an off-the-self device, which is applied for emergency cases. However, there is a concern that SEVAR lead to gutter leak due to insertion of multiple stents. Previously, we performed 2-staged treatment for gutter leak after SEVAR. However, the gutter leaks can also occur late, and it is often difficult to close. Therefore, if a significant gutter leak is identified intraoperatively, performing concomitant gutter coil embolization at the time of the initial surgery may be reasonable.
