Abstract
Physician-modified endovascular grafts (PMEGs), with fenestrations added to accommodate major branch vessels, provide a means for endovascular treatment of juxta-renal abdominal aortic aneurysms. Manual measurements of vessel origin locations from computed tomography images, however, take time and can lead to errors in the positions of the fenestrations. To make the fenestration process faster and more accurate, we have developed a procedure to create custom templates that serve as patient-specific guides for graft fenestration. We use a three-dimensional printer to create a clear rigid sleeve that replicates the patient’s aorta and includes holes placed precisely at the locations of the branch vessels. The sleeve is placed over the graft, the locations of the openings are marked with a sterile pen, and the fenestrations are created after the sleeve is removed. Custom fenestration templates can potentially save procedural costs and make minimally invasive aortic aneurysm repair available to many more patients. This chapter summarizes the 3D printing applications to create models for preoperative planning of PMEGs.
