Interobserver variability in physician-modified endograft planning by comparison with a three-dimensional printed aortic model

Physician modification of endografts is able to accommodate the patient's anatomy outside of currently commercially available fenestrated grafts. However, the fenestrations may not appropriately coincide with the native vessel ostial positions despite measurement with specialized software. This can create a situation of overlap or “eclipsing” and may thus influence branch vessel patency. Further study is needed to elucidate the clinical impact of this finding.
