Aortic diameter remodelling after the frozen elephant trunk technique in aortic dissection: results from an international multicentre registry†

Abstract

The FET technique provides an effective treatment for AoD, promoting FL thrombosis and remodelling in the descending thoracic aorta. Changes in the diameter of the aortic lumen depend mainly on the status of the FL and are similar between acute and chronic AoD. Changes in the diameter of true lumen are affected by both the FL status and the timing of the presentation. However, increased FL thrombosis and positive remodelling rates are not maintained at the level of the abdominal aorta, and strict follow-up is mandatory to detect early changes in the aortic dimensions, which may warrant further interventions.
