title: Molded Parallel Endografts for Branch Vessel Preservation during Endovascular Aneurysm Repair in Challenging Anatomy.
abstract: Parallel endografts (also known as snorkels or chimneys) are a proposed strategy for increasing the applicability of endovascular repair to aneurysms involving branch vessels. One major disadvantage of this strategy is the imperfect nature of seal inherent to having multiple side-by-side endografts. In this article, the use of odd-shaped parallel endografts to facilitate apposition and improve seal is proposed and a technique to mold a round stent graft into an "eye" shape using balloons is described.
