Determination, Calculation and Representation of the Upper and Lower Sealing Zones During Virtual Stenting of Aneurysms
This addresses the need for improved surgical planning in vascular interventions, though it appears incremental as it builds on existing stent simulation methods.
The paper tackles the problem of simulating stents for preoperative planning in aneurysm treatments by automatically calculating and visualizing sealing zones from CTA scans, with results demonstrated for abdominal, thoracic, and iliac aneurysms.
In this contribution, a novel method for stent simulation in preoperative computed tomography angiography (CTA) acquisitions of patients is presented where the sealing zones are automatically calculated and visualized. The method is eligible for non-bifurcated and bifurcated stents (Y-stents). Results of the proposed stent simulation with an automatic calculation of the sealing zones for specific diseases (abdominal aortic aneurysms (AAA), thoracic aortic aneurysms (TAA), iliac aneurysms) are presented. The contribution is organized as follows. Section 2 presents the proposed approach. In Section 3, experimental results are discussed. Section 4 concludes the contribution and outlines areas for future work.
