Endovascular repair of aortic arch pathologies currently requires custom‐made endografts to reflect an individual's anatomy, causing a treatment delay. This study's purpose is to identify common patterns in the anatomy of the type 1 aortic arch and its branches to aid in the development of an off‐the‐shelf endograft. TeraRecon 3D imaging software was used for morphological assessment of CT scans from 45 patients (26 M, 19 F; mean age 68). A total of 13 measurements were made including diameter, distance and orientation of vessels. Statistical analysis indicated various trends. The diameter of the aorta was larger more proximally (closer to the coronary arteries), the distance between the inominate artery (IA) and the left common carotid artery (LCC) was approximately half the distance measured between the LCC and the left subclavian artery (LSC). Branch ostia diameters consistently ranked in the following order IA>LSC>LCC. Lastly, the LCC orientation, with respect to the other two vessels, was within a 50° range. This study provides useful information for the production of an arch endograph prototype reflecting the anatomy of the majority of patients. Prospective validation of this design is required.
