Brief Summary

Abdominal aortic aneurysm, a condition characterised by an increase in the diameter of the aorta, can be treated either surgically or endovascularly. In the latter, an endoprosthesis consisting of a metal spring covered with an impermeable fabric is inserted through an artery and deployed inside the aorta. This new method appears to be less invasive than surgery, but its long-term results are not yet fully understood. As a result, patients who have undergone this treatment are monitored by their surgeon to ensure that there is no endoleak. Several research teams have proposed analysing medical images to predict this risk of endoleak. Doctors are now trying to use artificial intelligence to automate the analysis of these images.

Outcome Measures

Primary Outcomes (1)

  • Number of endoleaks following endograft implantation

    Endoleak is the most common complication after AAE placement, with incidence varying greatly depending on type and time elapsed since endoprosthesis placement. It is defined by blood circulation between the AAE and the arterial wall of the AAA. Five types of endoleak have been described according to anatomical, chronological, or physiological characteristics.

    From AAE placement to the end of the two-year follow-up

Secondary Outcomes (3)

  • Number of embolizations

    From AAE placement to the end of the two-year follow-up

  • Sac size

    Two-year follow-up

  • Number of serious adverse events

    From AAE placement to the end of the two-year follow-up

Study Arms (1)

Patient treated for an abdominal aortic aneurysm

Indications for infrarenal abdominal aortic aneurysm (AAA) treatment with abdominal aortic endoprosthesis (AAE) were : * AAAs with greatest diameter \> 50 mm for women and \> 55 mm for men, or diameter increase of more than 5 mm in six months and 10 mm in 1 year. * A symptomatic or complicated AAA is treated regardless of size. * Despite the absence of conclusive data, a saccular AAA is considered high-risk due to its particular morphology and is proposed for treatment even if its greatest diameter is \< 50 mm.

Procedure: Abdominal aortic endoprosthesis

Interventions

An endoprosthesis consisting of a metal spring covered with an impermeable fabric is inserted through an artery and deployed inside the aorta.
