Abstract
Thoracoabdominal aortic aneurysm (TAAA) is a severe and complex condition with multifactorial etiology that can
lead to life-threatening complications. Its treatment is genuinely complex irrespective of the chosen technique,
open or endovascular repair. Fenestrated-branched endovascular aneurysm repair (F/B-EVAR) has been
increasingly accepted in patients with suitable anatomy, resulting in outcomes compared to or superior to open
repair. The selection of patients, judicious surgical planning, and device selection are paramount to achieving
successful treatment. The field of TAAA repair is continuously evolving with ongoing research and the
development of new techniques and devices to further improve patient outcomes. This paper aims to present a
review of endovascular TAAA treatment, summarizing anatomical and clinical features relevant to technical
performance and treatment indications.

Keywords: F/B-EVAR, TAAA, thoracoabdominal aortic aneurysm, aneurysm, endovascular

INTRODUCTION
The endovascular treatment of thoracoabdominal aortic aneurysms (TAAAs) continues to evolve over time
[1]
with novel techniques and devices, expanding the pool of patients eligible for this approach . To
successfully repair complex TAAAs, one should take into consideration the anatomy of the patient, clinical
[2]
characteristics, and the anatomic suitability of each device . Fenestrated and branched grafts have had a
crucial role in improving outcomes, allowing treatment for high-risk patients who would not tolerate more
