Problem Formulation:
Endovascular aneurysm repair (EVAR) effectively treats aortic aneurysms but often faces challenges such as endograft migration, which can result in severe clinical complications. The deployment of EndoAnchors is designed to improve fixation and migration resistance, yet there is limited understanding regarding the optimal configuration and positioning of these anchors. Identifying the best practices for deploying EndoAnchors could significantly reduce migration risk and enhance patient safety.
Project Tasks:
-
Background Research:
-
Review current literature on EVAR, emphasizing migration risks and current fixation technologies, with a particular focus on the Heli-FX EndoAnchor system.
-
-
Experimental Methodology:
-
Understand and operate the existing in vitro experimental apparatus used to assess displacement resistance of aortic endografts.
-
Conduct validation procedures for the experimental setup (including silicone models, sensors, and imaging equipment).
-
-
Configuration Evaluation:
-
Systematically test different configurations of EndoAnchors, including varying circumferential distributions and distances between anchors.
-
Record displacement force (EDF) for each configuration under controlled experimental conditions.
-
-
Statistical Analysis:
-
Analyze collected data using statistical tools to determine which configurations offer superior resistance to displacement.
-
Draw meaningful conclusions from the statistical analysis regarding optimal anchor placement.
-
-
Documentation and Recommendations:
-
Draft a comprehensive report detailing the methodology, experimental findings, and potential clinical implications.
-
This project offers a valuable opportunity to improve clinical outcomes in vascular surgery through advanced insights into endograft fixation strategies.
