Early Experience With the Twin Branch in the Endovascular Treatment of Complex Aortic Aneurysms: A Multicenter Retrospective Study

The twin branch is a feasible option in the treatment of complex aortic aneurysms with certain anatomic variations. Simultaneous inflation of both stent grafts should be performed to avoid compromising a previously-inflated stent graft.Clinical ImpactThe twin branch was developed as a component of the E-xtra Design MultiBranch stent graft system (Artivion, Hechingen, Germany). In this multicenter retrospective study, we demonstrate that the twin branch is a feasible option in the treatment of complex aortic aneurysms where a regular F/BEVAR is not possible because of the visceral vessels originating in close proximity to each other and where the aortic lumen is too narrow to allow for external branches. The short-term outcomes show a good technical success rate. Simultaneous insufflation of bridging stents might be beneficial to maintain target vessel patency..
