Tabular review of contemporary fenestrated-branched endovascular aortic repair experiences for treatment of thoracoabdominal aortic aneurysms.

Abstract

Introduction: Repair of thoracoabdominal aortic aneurysms (TAAAs) represents a technical challenge regardless of which technique is used. Open surgical repair (OSR) is the time-tested option against which novel techniques must be compared and it is still considered the gold standard option for younger, fit patients with heritable aortic diseases. Endovascular repair offers a less-invasive alternative in patients with suitable anatomy. This article aims to present a tabular review of the contemporary published data on endovascular repair of TAAAs using fenestrated-branched techniques.

Evidence acquisition: The published literature for single-center and multicenter studies evaluating the outcomes of FB-EVAR for TAAAs was searched using MEDLINE and Embase databases. Studies published between January 1^st 2010 and July 11^th 2024, in the English language which provided data on FB-EVAR of TAAAs with more than fifty reported cases were included.

Evidence synthesis: The average patient age at time of repair was 71 years old with majority of males (65.5%). Most patients presented with a Crawford Extent II TAAAs (21.6%), followed by Extent III (21.2%). Early mortality was 4.9% for the entire cohort. The most prevalent adverse event was acute kidney injury (9.4%), followed by spinal cord injury (8.0%).

Conclusions: FB-EVAR of TAAAs continues to evolve. Pooled analysis of early mortality and morbidity is lower in this tabular review than historical outcomes of open TAAA repair.
