A Review: Single and MultiBranch Devices for the Treatment of Aortic Arch Pathologies with Proximal Sealing in...

Recently published experience has shown that endovascular management of the aortic arch, including sealing in the proximal zones, can be a viable option for patients considered unfit for conventional open repair. Endograft designs vary and include single or multibranch devices, with or without the addition of surgical debranching. Initial reports show that both techniques can be performed with high technical success and acceptable perioperative morbidity and mortality rates in high volume centers. Single branch devices, available off-the-shelf, may provide a treatment option for emergent presentations where patients cannot wait for the design and manufacture of a customized endograft. Double or triple branched endografts are now increasingly implanted in high-volume aortic centers. The purpose of this review is to describe the single and multibranched endovascular devices currently available for aortic arch repair, their associated published outcomes, and to discuss their relative advantages and disadvantages.
