5. Conclusion
The present meta-analysis of 5068 patients with TAAD and/or thoracic aortic aneurysm undergoing FET procedure provides a clear understanding of the incidence of FET complications, including negative aortic remodeling, dSINE and endoleak. These events may necessitate secondary endovascular intervention, thus minimizing their incidence is ideal. Therefore, the choice of FET graft type, size and length must be taken with great care. In addition, patients’ clinical/anatomical characteristics should be seriously taken consideration. Nevertheless, Thoraflex Hybrid can be considered the primary FET device choice due to its superior results. Finally, in our results the type of stent-graft and the study location were sources of heterogeneity, emphasizing the need for multicenter studies directly comparing FET grafts.
