Evaluating imaging methods for detecting endoleaks in aortic patients

Concordance of Three Imaging Methods by Dynamic CT, Contrast Ultrasound and CT Angiography in the Characterization of Endoleaks in Patients With an Aortic Endoprosthesis

Not applicable Interventional Centre Hospitalier Universitaire, Amiens · NCT06318780

This study is testing three different imaging methods to see which one works best for finding leaks in the blood vessels of patients who have had surgery to repair an aortic aneurysm.

What this trial studies

This study investigates the effectiveness of three imaging techniques—dynamic CT angiography (d-CTA), contrast-enhanced ultrasound (CEUS), and traditional three-phase CT angiography—in identifying and characterizing endoleaks in patients who have undergone endovascular aneurysm repair (EVAR). Given the significant risk of endoleaks post-EVAR, which can lead to serious complications, the study aims to improve diagnostic accuracy and patient outcomes. Participants will be monitored for endoleaks and aneurysmal sac enlargement, with a focus on enhancing current imaging protocols.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older who have undergone EVAR and exhibit signs of endoleak or significant aneurysmal sac enlargement.

Not a fit: Patients without endoleaks or those whose aneurysmal sac has not enlarged significantly over the specified period may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved detection and management of endoleaks, reducing the risk of complications for patients with aortic endoprostheses.

How similar studies have performed: While there is ongoing research in imaging techniques for endoleaks, this specific combination of d-CTA and CEUS in this context is relatively novel.
