Three-dimensional printed templates to guide fenestrated endovascular aneurysm repair are not as straightforward as they appear

摘要

The current delay in receiving commercially availablefenestrated endografts has proved fatal for somepatients. In addition, efforts to reduce planningcomplexity and to increase fenestration location accu-racy, thereby expediting the implantation procedure,are appreciated. Indeed, we agree that part of the reasonfor the relatively slow adoption of fenestrated endovas-cular aneurysm repair relates to case planning andprocedural complexity.
