Back-table fenestrated endograft limb inversion for type Ia endoleak repair.

We present a case of a type Ia endoleak from an aortic endograft in close proximity to the renal arteries that was successfully treated with a back-table physician-modified endograft with inversion of the contralateral limb. This modification allowed for deployment of a fenestrated cuff and bifurcated distal main body over the flow divider of the previous endograft, thus avoiding the need for either an open aneurysm repair, physician-made fenestrations, or aorto-uni-iliac repair with femoral-femoral bypass. This case demonstrates that back-table physician-modified endograft contralateral limb inversion is an easy, reproducible, and effective technique.

Laser Fenestration in TEVAR: Perspectives and Future Directions.

Endovascular aortic repair has been increasingly used to treat a multitude of thoracic aorticpathologies. When placement of a thoracic endograft necessitates coverage of one or more of the great vessels, in situ laser fenestration is a safe and effective option for supra-aortic trunk revascularization. Certain anatomic factors may render laser fenestration more technically challenging, particularly depending on aortic arch type and branch vessel characteristics.
