Translumbar type II endoleak embolization using real-time needle guidance and fluoroscopy overlay on pre-treatment CTA

We decided to plan the intervention with the XperGuide software and verify the feasibility of a translumbar approach by drawing the puncture path on the diagnostic CTA image, because this optimally shows shape and volume of the targeted endoleak (Figure 2a). In general, we recommend the use of delayed phase CTA, although in this specific case we used the arterial phase because it still offered a good depiction of the endoleak and a better spatial resolution in the sagittal and coronal planes, which are used to guide needle puncture.
