Virtual angioscopy and 3D navigation of the aorta

Abstract

The objective of this study is to demonstrate the applicability of virtual angioscopy (VA) in different forms of aortic disease where the diagnosis is unclear or uncertain. Five cases are presented where VA helped to establish a correct diagnosis and to choose the best surgical strategy by providing an intuitive image of the aorta.

Failure of CT angiogram to detect an ascending aortic dissection

“…Computed tomography angiography (CTA) is currently the imaging modality of choice to evaluate acute aortic pathology. Their quality may be enhanced with 3D modeling and 3D navigation with virtual angioscopy to assist in determing the best surgical strategy . However, dissections may still be missed on two‐dimensional CTAs .…”
