FEVAR & BEVAR — Complex Aortic Repair
Fenestrated (FEVAR) and branched (BEVAR) endovascular repair extend the stent-graft approach to complex aortic anatomy where branch vessels — renal and visceral arteries — must be preserved. These techniques are used in selected cases after detailed anatomical evaluation.
What is FEVAR?
FEVAR uses a stent graft with fenestrations (openings) aligned to branch vessels, so the renal and visceral arteries remain perfused while the aneurysm is excluded — in suitable anatomy and according to manufacturer instructions for use.
What is BEVAR?
BEVAR uses a stent graft with integrated side branches to perfuse vessels in thoracoabdominal and complex anatomy. Device and technique selection depends on detailed imaging and physician judgement.
When are complex techniques considered?
FEVAR and BEVAR may be considered when the aneurysm neck or extent involves branch vessels, making a standard EVAR or TEVAR unsuitable. Planning typically requires precise sizing from cross-sectional imaging.

Frequently asked questions
What is FEVAR?+
FEVAR is an EVAR technique for complex anatomy that uses a fenestrated stent graft to preserve renal and visceral branch vessels.
What is BEVAR?+
BEVAR uses a branched stent graft to perfuse side branches in thoracoabdominal anatomy; it is used in selected cases.
What is the fenestration technique?+
An approach for complex aortic anatomy where openings (fenestrations) in the stent graft keep branch vessels patent.
What is a branched stent graft?+
A stent graft with integrated side branches, designed to preserve branch vessels in thoracoabdominal and complex aortic anatomy.
What is Chimney EVAR?+
The chimney technique places parallel stents alongside the main stent graft to preserve branch vessels, used in appropriate cases.
