In the emerging field of total endovascular repair of thoracoabdominal aneurysms, there currently are four techniques used for repair: the sandwich technique, the double barrel technique,1 the fenestrated technique and the branch graft technique. Most centers with expertise in this procedure favor one of these techniques depending on investigational device exceptions (IDEs) or ongoing industry-sponsored trials.
Because surgeons at the USC CVTI are experienced in all four techniques, we are able to examine each patient’s aortic anatomy and determine the technique that will work best. In addition, our team of experts has further refined the sandwich technique into a procedure termed “multilayered parallel grafting.”
