Outcomes of Secondary Endovascular Aortic Repair After Initial Frozen Elephant Trunk Procedure

30 participantsStarted 2015-01-01

Plain-language summary

Objective Complex aortic pathology has been revolutionized with the use of hybrid prostheses such as the Thoraflex® Hybrid Frozen Elephant Trunk (FET). The aim of this study was to evaluate the midterm results of secondary extension of the FET by thoracic endovascular aortic repair (TEVAR). Few data are present in the literature regarding the outcomes of this secondary treatment. The investigators perform a prospective study between 2015 and 2022 in a tertiary aortic center on all consecutive patients having undergone TEVAR after FET implantation. The TEVAR endograft covered most of the 10 cm FET module with 2 to 4 mm oversizing. All patients were monitored by computerized angiography (CTA) at 6-month and yearly thereafter. The aim of this study was the feasibility of theses secondary connexion and the mid term outcomes of the endovascular treatment.
