Review the imaging monitoring protocols of aortic aneurysms treated with endoprotheses. Describe the typical post treatment findings of acute and chronic complications after endovascular aortic repair (EVAR) of abdominal aneurysms.

In the last years there have been an increase of EVAR and secondarily, in the number of postreatment imaging controls. This protocol of imaging follow up intends to detect aneurysm growth, endoleaks, prothesis dislogement, thrombosis or infection.

CT is the preferred method, because its availability, speed and spatial resolution, although there are many descriptions using ultrasound/doppler or enhanced MRI. We found an article using unenhanced CT with aneurysm volumetric calculation, considered to be normal a maximum increase of 2% by volume, due to error from estimation, and in case of a variation of >2%, the patient should be evaluated with standard enhanced CT technique. Studies describe o recommend to assess at 1st month, 3rd month, 6th month and if no abnormalities are...

The post-treatment follow-up of endovascular abdominal aortic aneurysms, its based on the CT imaging study, because it is considered the gold standard for the assessment of complications, so, their knowledge is essential for general or the body image dedicated radiologist.
