Enlarging Paravisceral Aortic Aneurysm Treated With In Situ Laser Fenestration of Physician-Modified Stent Graft for Preservation of Accessory Renal Arteries.

In situ laser fenestration will provide surgeons with a valuable intra-operative method to create additional stents when organ perfusion would otherwise be lost. As more surgeons develop this technical ability and more long-term outcomes are studied, this method has the possibility to not only be used for urgent and emergent cases but may one day be an acceptable variation to standard practice.
