Artificial intelligence to predict complications after abdominal aortic endoprosthesis
Official title: Implantation of an Endovascular Prosthesis for the Treatment of Abdominal Aortic Aneurysms: Use of a Machine Learning Model From CT Images to Predict Complications
Run by Groupe Hospitalier de la Rochelle Ré Aunis · NCT06884397 · Data updated 2026-11-12
This project will try an AI tool to predict endoleaks and other complications from CT and angiography images in people treated with an abdominal aortic endoprosthesis.

Is this trial a fit for you?
✓Likely a good fit
Adults treated for an infrarenal abdominal aortic aneurysm with an endovascular endoprosthesis who have follow‑up CT or angiography imaging and did not undergo intraoperative embolization of the inferior mesenteric artery or aneurysm sac are the ideal candidates.
✕Probably not a fit
Patients who had open surgical repair instead of an endovascular prosthesis, those without suitable imaging or follow‑up, or those who underwent intraoperative embolization are unlikely to benefit from this AI approach.

What this trial studies
This observational effort uses routine CT and angiography images from patients who received an abdominal aortic endoprosthesis to train and test a machine‑learning algorithm to predict post‑procedure complications such as endoleak. Patients treated and followed at Groupe Hospitalier de la Rochelle Ré Aunis who meet inclusion criteria will provide the imaging and outcome data, with exclusions for intraoperative embolization of the inferior mesenteric artery or aneurysm sac. The algorithm will be developed on retrospective image sets and validated on separate patient scans by comparing predictions to documented clinical outcomes. The aim is to automate image analysis to improve detection and risk stratification during long‑term follow‑up.
Why it matters
Potential benefit: If successful, the tool could identify patients at higher risk of endoleak earlier, allowing targeted follow‑up and quicker treatment to reduce complications.
How similar studies have gone: Previous small studies using machine learning on CT images have shown promising results for detecting or predicting endoleak, but large prospective validation remains limited.
