About

Fenestrated stents are used for the management of complex juxta-renal, para-renal or thoracoabdominal aneurysms in patients with high surgical risk and/or contraindicated for open surgery. These endovascular techniques have demonstrated their safety and efficacy, however, long-term follow-up CT scans remain essential for the detection of complications such as endo-leaks and restenosis/thrombosis of visceral and renal stents. The respiratory cycle might induce changes in the geometry and deformations of visceral and renal stents after complex aortic procedures. These could be detected by an adapted CT scan analysis by deep inhalation and deep exhalation acquisition carried out pre-operatively and post-operatively for monitoring of these same stents and screening for complications.

Protocol

Experimental group

Description:

Each patient agreeing to participate in the study will be distributed in the protocol group and will receive an angioscan according to the protocol in pre-operative and at the usual post-operative check-up within 3 months after the operation. The usual procedure, foresees an angioscanner with injection of contrast product and the measurement of the images is performed during a deep breath. In order to obtain a complete respiratory cycle, the study procedure foresees in addition to the usual procedure, an image measurement during a deep exhalation.

Treatment:

Procedure: Angioscan
