Take Home MessageTranslumbar Type 2 endoleak embolisation is safe & efficient
Faster than transarterial for lumbar embolization
Intermediate assessments with Stereo 3D instead of additionalCBCT
Easy with Discovery IGS 730 with Needle ASSIST
LumbarIMA
Transarterial
(Check intestinal arterial arcade)Translumbar
if accessible fromthe left/right side
Growing aneurysm with type II
Rule out Type I or III
if not
Transarterial
