Aneurysm of the abdominal aorta is defined by a loss of parallelism of the arterial wall.
The main risk of this pathology is the rupture of the aneurysm which is life threatening
and this risk increases with the size of the aneurysm. Connected stents allow the
management of complex thoracoabdominal aneurysms in patients at high surgical risk and/or
contraindicated for open surgery. These endovascular techniques have demonstrated their
safety and efficacy, however, long-term CT follow-up remains essential to detect
complications such as endo-leaks and restenosis/thrombosis of visceral and renal stents.
The prognostic factors of these complications remain poorly elucidated. The type of stent
to be used could be an explanation, however, no stent has been proven to be superior in
this application to date. Data from the literature suggest an influence of stents on the
aortic geometry and the arterial axes of the digestive tract during respiratory
movements. The work of the Stanford vascular surgery team shows that the deformations and
modifications of the geometry of these stents induced by the respiratory cycle could have
a negative impact by migration, stenosis and thrombosis.
