Brief Summary
This pilot study aims to quantitatively characterize the stresses and forces on an implanted endograft during the cardiac cycle in patients scheduled for standard endograft follow-up. The developed techniques will be applied in future studies for characterizing and comparing the currently commercially available endografts so as to gain insight into the mechanisms underlying potential endograft failure. In addition, to assist in developing endografts with long-term durability and functioning characteristics for the benefit of the patient

Outcome Measures
Primary Outcomes (1)
to quantitatively characterize the stresses and forces on an implanted endograft during the cardiac cycle in terms of longitudinal movement
Secondary Outcomes (1)
evaluate the integrity of the endograft by visualization using CT in the longitudinal and transversal plane at several moments during the cardiac cycle versus the standard transverse plane method
Study Arms (2)
1
Preoperative patients planned for a CT prior to an endograft implantation procedure
2
Patients who underwent a complicated endograft implant and/or with increased risk of complications
Eligibility Criteria
patients undergoing either a preoperative CT procedure or with an implanted aortic endoprothesis (-graft) presenting to the department of radiology for a scheduled follow-up CTA procedure.
You may qualify if:
- Preoperative patients planned for a CT prior to an endograft implantation procedure
- Patients who underwent a complicated endograft implant and/or with increased risk of complications
- years of age or older
- Patients who have given their informed consent
You may not qualify if:
- Known allergy for contrast medium
