A Systematic Review of Contemporary Outcomes from Aortic Arch In-Situ Laser Fenestration During Thoracic Endovascular Aortic Repair.

In situ laser fenestration is a feasible, safe and effective approach to treat aortic arch disease in patients who are unsuitable for open or custom-made endovascular means. High technical success and excellent short-term branch patency can be achieved. These single-institution series exhibit promising short-term outcomes. In a similar paradigm to investigational device exemptions studies for custom-made and physician modified endografts, these preliminary data make a persuasive argument for larger long-term multi-institutional prospective study of this promising technique.
