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. Short-term and mid-term outcomes have shown promising results for mortality, stroke, and complication rates. Future developments may extend the utility of this approach and allow it to be applied to a more widespread set of patients with challenging anatomy.
