Back Table Modification of Bifurcated Endurant Stent Graft to Aorto-Uni-Iliac Stent Graft to Treat Chronic Failure of Endovascular Abdominal Aortic Repair (EVAR) for Abdominal Aortic Aneurysm

Q: What is the clinical evidence from this study?

Study design: Case Report. Population: Chronic failure of Endovascular Abdominal Aortic Repair (EVAR) for Abdominal Aortic Aneurysm (n=1). Intervention: Back table modification of Endurant bifurcated stent graft to an aorto-uni-iliac (AUI) stent graft. Primary outcome: Aneurysm regression and absence of complications.

Key result

Re-EVAR using a back-table modified aorto-uni-iliac stent graft followed by a crossover femoro-femoral bypass successfully treated a failed EVAR, resulting in marked aneurysm regression at one year without complications.

Why the study?

Does back table modification of a bifurcated stent graft to an AUI stent graft allow successful re-EVAR in a patient with chronic EVAR failure and unsuitable anatomy?

Structured PICO

Does back table modification of a bifurcated stent graft to an AUI stent graft allow successful re-EVAR in a patient with chronic EVAR failure and unsuitable anatomy?

P

Population

A woman in her 80s with chronic failure of EVAR for an abdominal aortic aneurysm and challenging anatomy, followed for 1 year after re-intervention.

I

Intervention

Re-EVAR using a back table modification of the Endurant bifurcated stent graft to an aorto-uni-iliac (AUI) stent graft, followed by a crossover femoro-femoral bypass.

O

Outcome

Aneurysm regression and absence of complications at 1-year follow-up.surrogate

Limitations

At least 10 mm of sealing area is needed to achieve a sufficient seal of the aneurysm.
The long-term durability of this technique has not been confirmed.
Inherent additional risks associated with a cross-over bypass, including graft thrombosis, infection, and pseudoaneurysm formation.

Implication

Back table modification of a bifurcated stent graft to an AUI device is a feasible and effective option for re-EVAR in patients with challenging anatomy when a manufactured AUI device is unavailable.

Abstract

A patient who had previously undergone endovascular abdominal aortic repair (EVAR) of an abdominal aortic aneurysm was found to have aneurysmal growth 5 years after the initial EVAR and endovascular reintervention was considered. However, the patient was deemed unsuitable for an ordinary bifurcated stent graft. Re-EVAR was successfully conducted with a back table modification of the Endurant bifurcated stent graft to an aorto-uni-iliac (AUI) stent graft in a setting where a manufactured AUI stent graft was not available; this procedure was followed by a crossover femoro-femoral bypass. The patient's one-year follow-up exam revealed a marked regression of the aneurysm without any related complications. This modified technique may extend the limits of abdominal endovascular treatment for patients who are not suitable for a bifurcated stent graft and may be applicable in situations where adequate AUI devices are not available.

Hongo et al. (2016) conducted a case report in Chronic failure of Endovascular Abdominal Aortic Repair (EVAR) for Abdominal Aortic Aneurysm (n=1). Back table modification of Endurant bifurcated stent graft to an aorto-uni-iliac (AUI) stent graft was evaluated on Aneurysm regression and absence of complications. Re-EVAR using a back-table modified aorto-uni-iliac stent graft followed by a crossover femoro-femoral bypass successfully treated a failed EVAR, resulting in marked aneurysm regression at one year without complications.
