Overview

Among patients who have undergone EVAR, there is a significant risk of 20-50% endoleak. These endoleaks often require secondary interventions to reduce the risk of expansion or rupture. Currently, three-phase CT angiography and CEUS ultrasound are recommended in the post-operative monitoring of EVAR but these remain limited in characterizing the type and source of endoleak. In this study the investigators will study the interest of d-CTA for a better detection and characterization of endoleaks.

Eligibility

Inclusion Criteria:

  • Patients 18 years of age and older,
  • Patients who have received EVAR ,
  • Detection of endoleak and/or with an aneurysmal sac enlargement greater than or equal to 5 mm over 6 months.

Exclusion Criteria:

  • Minor patients,
  • absence of endoleak and growth of the aneurysmal sac (greater than or equal to 5 mm over 6 months),
  • patient under guardianship, curators, safeguard of justice,
  • patient deprived of liberty,
  • pregnant woman
  • Patient who does not benefit from a social security scheme

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
