Fenestrated Aortic Endografts in the Last 3 Years: An Update

Abstract

Purpose of Review

Fenestrated endovascular aortic aneurysm repair (FEVAR) is an accepted treatment option for patients who are not suitable for conventional endovascular aortic aneurysm repair or open surgical repair (OSR). Five years ago, the FDA approved the use of FEVAR in patients with inadequate infrarenal aortic seal zones (short necks). This procedural paradigm continues to gain in popularity compared to OSR for complex aortic disease. We seek to define the current state of fenestrated endovascular repair by reviewing relevant literature over the past 3 years.

Recent Findings

FEVAR continues to prove to be efficacious with reasonable durability as a therapy for patients who are not candidates for OSR. As a second-line treatment, FEVAR is less morbid in the short-term with trade-off of high reintervention rates in the follow-up period. Mid- to long-term outcomes have proven to be comparable to OSR in selected patients with persistent excellent patency of the visceral target vessels. Recent publications have thrust FEVAR into consideration as the primary interventional modality in juxtarenal abdominal aortic aneurysms, a traditional indication for OSR.

Summary

As FEVAR continues to evolve from surgeon-modified devices to custom built and eventually off-the-shelf grafts, it is anticipated to be employed widely for managing complex aortic aneurysms. Compared to OSR, FEVAR carries a low risk of perioperative morbidity while demonstrating continued safety and durability in early to mid-term reports.
