EVAR is performed to replace open surgeries for patients with AAA. The prostheses act as a bypass channel for blood flow through the aneurysm, preventing its enlargement and rupture. Regular follow-up imaging is necessary for all EVAR patients to assure the patency of the prostheses, as well as to rule out potential endoleaks. These occur in approximately 25% of the EVAR patients. Once an endoleak is identified, it is critical to determine the endoleak type for patient management. A type III endoleak is considered a high pressure leak and requires urgent treatment due to the high risk of sac rupture. CTA can precisely illustrate the site and the type of endoleaks and is the modality of choice.  This case presents a rare EVAR complication – a complete occlusion of the left iliac prosthesis and a concurrent endoleak salvaging the blood flow in the left leg. A dual energy (DE) CTA mode is performed which applies a special filter technique, Selective Photon Shield, enabling significant separation of energy spectrums at 80 and 140 kV settings. The attenuation measurements acquired at these two kV settings can be calculated to display images at lower keV levels to significantly enhance the contrast, using “syngo. CT DE Monoenergetic Plus”. The same image data can also be used to generate iodine images showing contrast enhancement, as well as virtual non-contrast (VNC) images simulating native scan, using “syngo. CT DE Virtual Unenhanced”. These two types of image presentation help physicians differentiate hyperdensities, for example, the contrast enhanced endoleak and the calcification of the aneurysmal wall. The bone structures can be removed using “syngo. CT DE Direct Angio” to show non-obscured vasculature. All these applications are performed in an automated workflow. Advanced techniques, such as cinematic volume rendering technique (cVRT), are also applied to enable a lifelike, three-dimensional demonstration of the anatomical details facilitating an easy and straightforward communication.
