ABSTRACT
BACKGROUND:
Recent advances in surgical repair of aortic arch pathologies have increasingly used endovascular stent-graft technology. The purpose of this study was to map the aortic arch diameters, branch orientations, and center line distances using a commercially available three-dimensional computed tomography-based software package and to propose a prototype design.METHODS:
TeraRecon 3D imaging software was used for morphological assessment of computed tomography scans from 45 patients (mean age 68 years; 26 males, 19 females). In each patient, 13 measurements were made in relation to the center line, including diameters at several preset points, distances, and branch vessel orientations.RESULTS:
The mode of the proximal diameters (2 cm and 4 cm distal to coronary artery) was 32 mm and 34 mm. The mode of the distance between the innominate and left common carotid arteries was 5 mm and 6 mm, and the mode of the distance between the left common carotid artery and left subclavian artery was 8 mm. Most commonly, the left common carotid artery was anterior to the other arch branches by 3 to 5 mm.CONCLUSIONS:
These anatomic measurements provide useful information for the advancement of minimally invasive and safer surgical repair of the aortic arch. Based on the most commonly observed measurements, a standardized off-the-shelf stent-graft is proposed that would be appropriate for the majority of patients.
