Technical tips and clinical experience with the Terumo Relay ®Branch aortic endovascular graft

J Cardiovasc Surg (Torino). 2023 Feb;64(1):26-32. doi: 10.23736/S0021-9509.22.12552-8.ABSTRACTAdvances in thoracic endovascular aortic repair (TEVAR) are enabling the treatment of increasingly proximal pathology. While the practice of vascular surgery has thus far been mostly limited to TEVAR in zone 2 or more distally, there are emerging devices for zone 1 and zone 0 repair that do not require any further arch debranching compared with a zone 2 repair. Moreover, such devices set forth repair options for patients unable to tolerate the insult of open surgery. One zone 0 device under evaluation is the Terumo Relay®Branch (Terumo, Tokyo, Japan) endovascular graft, which is an off-the-shelf device based on the Relay®Pro platform (Terumo). This double branch device uniquely features a large gate, facilitating easy cannulation that contains two locking portal stents for the innominate artery (IA) and left common carotid artery (LCCA) branch grafts. Within our institution, we have had excellent technical success with Relay®Branch (Terumo) device deployments as part of the Early Feasibility Study, and other centers outside of the USA have published results with this device in small patient series. Notably, there is still a concerning stroke rate associated with the Relay®Branch (Terumo) device, with permanent stroke rates higher than expected but similar to those for open repair. Thus, these interventions must be undertaken with careful patient selection, thorough planning, and ...
