Objectives: Optimal timing for intervention for abdominal aortic aneurysms remains unclear. Given the increased rupture risk with larger aneurysms, timely intervention is critical. This study sought to examine endovascular aortic aneurysm repairs (EVAR) delays across Canadian centers, focusing on potential differences related to geography, sex and race.

The orientation of a blood vessel as visualized in 3D medical images is an important descriptor of its geometry that can be used for centerline extraction and subsequent segmentation, labeling, and visualization. Blood vessels appear at multiple scales and levels of tortuosity, and determining the exact orientation of a vessel is a challenging problem. Recent works have used 3D convolutional neural networks (CNNs) for this purpose, but CNNs are sensitive to variations in vessel size and orientation.
