Summary

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.
