Prediction of Abdominal Aortic Aneurysm Shrinkage After Stent-placement With Artificial Intelligence

ClinConnect Summary

This clinical trial is looking at how certain factors can help predict whether an abdominal aortic aneurysm (AAA) will shrink after a stent is placed. An AAA is when the main artery in your belly becomes enlarged, which can be dangerous. The researchers want to develop a model using artificial intelligence to better understand what leads to successful treatment outcomes one year after the stent placement.

To be eligible for this study, participants must be at least 18 years old and have undergone a specific type of procedure called elective infrarenal endovascular aneurysm repair (EVAR) for an unruptured AAA. They should have had a successful procedure and be using certain approved stent devices. Participants will need to have follow-up imaging done at least a year after their procedure to help evaluate the results. This study is currently recruiting and welcomes all genders. If you join, you can expect to contribute to important research that may improve future treatments for AAA.

• • Patients that were treated with fenestrated or branched endografts, iliac branched devices, non-CE marked devices within trial setting, other endografts (EVAS cases) or chimney procedures;
• • Acute procedures;
• • Reintervention before one year follow-up;
• • Revision cases after previous open or endovascular aneurysm repair of an AAA;
