Migration d’endoprothèse aortique : une complication rare après traitement endovasculaire

EVAR and OPEN treatment of abdominal aortic aneurysm: What is the role of MMP-9 in the follow-up?

“…The sac enlargement in the following period is also an important factor: as Bastos Gonçalves and colleagues report clinical success was highly dependent on sac growth and the generation of the implanted device influence sac growth and the original design grafts increase the risk of sac growth significantly [36]. Also in the Kaouel experience, the conversion after 18 months was necessary [37].…”

“…It may be speculated that the plasma assay of MMP-9 plays a potential role as a marker in the follow-up of patients who have received surgical or endovascular treatment; if necessary, the assay can be supplemented by an ultra-sonographic examination with echo-amplifying agents [39,40]. In fact, the spiral angio-CT presents diagnostic limits in identifying conditions of endopressure, even with the aid of coronal and sagittal axial multi-planar two-dimensional algorithms of reconstruction (MPR) and in particular with techniques of maximum intensity of projection (MIP) and volume rendering (VR) [35,37]. In a study carried out on a follow-up three years after insertion of an aortic stent-graft, Bendick compared the angio-CT examination to the ultra-sonographic examination with echo-amplifying agents and showed their sensitivity and specificity in monitoring complications, but less so for morbidity [41].…”
