Paper Abstract

The characterization of the vessel and its lesion is part and parcel of any patient specific planning of endovascular interventions. Thanks to the virtual exploration of a CT volume image acquired under clinical routine conditions we provide the practitioner with the primary elements to plan the intervention. Thus, the curve representing the evolution of the area of the lumen cross-section along the vessel centerline as well as the localization of the stenosis are derived from the virtual exploratory navigation. Due to the lack of reference in medical applications, an animal model of stenosis has been created and used to evaluate our approach. The stenosis characterization through virtual exploratory navigation has been applied to a set of ten sheep iliac arteries and compared with the characterization performed from classical reformatted CT slices and histological cross-sections. The validation of this virtual navigation based analysis is essential to the elaboration of planning systems aimed at the prevention of restenosis phenomena in transluminal angioplasty (accurate localization and covering of the lesion), as well as the treatment of the restenosis phenomena by intravascular brachytherapy (taking the vessel geometry into account).
