About this trial

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.

Trial outcomes

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.

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

Secondary outcomes

1

Number of embolizations

Minimally invasive treatment that blocks one or more blood vessels or abnormal vascular channels

Time frame
From AAE placement to the end of the two-year follow-up
2

Sac size

Normal aortic diameter varies with age, sex, and body habitus, but the average diameter of the adult human infrarenal aorta is approximately 2.0 cm. In most adults, an aortic diameter \>3.0 cm is generally considered aneurysmal.

Time frame
Two-year follow-up
3

Number of serious adverse events

deaths, ruptures, endoleaks, limb occlusions, and reinterventions

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