Patient and Staff Safety During Aorto-iliac Revascularization Procedures Under Automated Fusion Imaging Guidance With Controls

Not Applicable

Terminated

• Conditions: Patient and Staff Radiation Exposure During Aorto-iliac Endovascular Revascularization

• Registration Number: NCT03713450
• Lead Sponsor: Nantes University Hospital

Brief Summary

Endovascular revascularization has revolutionized the field of vascular surgery and has become the first-choice treatment for peripheral arteries occlusive disease. However, the drawback of this technic is the X-ray exposure for both patients and staff and the iodinated contrast injection for the patient.

One way to reduce both radiation and contrast use is to use advanced imaging techniques allowing an overlay of a 3D vascular mask (from a pre-operative CT scan) onto the live X-ray image. This has been proven during endovascular aneurysm repair.

This advanced imaging application is currently available only in the latest expensive hybrid operating rooms, requires additional manoeuvre from the operator throughout the procedure, and may be X-rays and contrast consuming.

This trial will examine the clinical benefits based on patient and staff' radiation exposure during aorto-iliac revascularisation, of a new software imaging guidance, suitable for any theatre including those equipped with mobile C-arm, fully automated and with a radiation free overlay registration process.
