Assembly and deployment of a branched arch stent graft using the transaortic approach.
Transaortic stent grafting is an alternative method for treating distal arch aneurysms. Total arch grafts are too bulky to be inserted into a sheath catheter during usual stent grafting methods. An assembling method that uses a chain stitch enables the deployment of any type of stent graft into the distal aorta without the need for a sheath catheter. We describe how to safely assemble and use a branched arch stent graft. We consider this method to be beneficial in selected cases involving extensive distal arch aneurysms or in patients with highly calcified aortas.
