Using artificial intelligence to predict abdominal aortic aneurysm shrinkage after stent placement

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to identify factors that contribute to successful treatment outcomes in patients who have undergone elective endovascular aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA). The primary objective is to develop a predictive model for the shrinkage of AAA one year post-treatment using artificial intelligence. Eligible patients must have received specific types of endografts and have follow-up imaging available for analysis. The study will analyze preoperative imaging data to enhance understanding of aneurysm remodeling.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Age ≥ 18 years;
* Elective, initially technically successful (as described by the ESVS guidelines11), infrarenal EVAR for unruptured infrarenal AAA;
* Implanted endograft is a Gore Excluder, Medtronic Endurant, Cook Zenith, Cordis Incraft, Endologix AFX, Jotec E-Tegra, or Vascutek Anaconda endograft;
* Follow-up of the AAA of at least one year with imaging of the same modality as the preoperative imaging;
* Axial reconstructions of preoperative CT angiography available, preferably in the arterial phase and with 3 mm or smaller slice thickness.

Exclusion Criteria:

* Patients with ruptured or symptomatic 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;
