Abstract

Endovascular treatment of giant, fusiform and dissecting aneurysms with flow diverter stents is becoming more and more popular. However, very few studies on the follow-up have been published. We describe a patient with a dissecting aneurysm of the right vertebral artery treated with flow diverter stent placement. The patient was followed up with CT angiography (CTA), time-resolved contrast-enhanced MR angiography (CE-MRA) and digital subtraction angiography (DSA). CTA had false negative results in two instances, whereas time-resolved CE-MRA and DSA were the most accurate in depicting the residual flow in the aneurysmal sac. However, in the case of DSA the demonstration of residual flow proved quite difficult and required a very thorough examination with oblique projections. Our 2.5-year experience with this patient led us to believe that time-resolved CE-MRA is a valuable tool in the follow-up of flow diverter-treated stents.
