Abstract:
Introduction:
A 65-year-old patient presented with subtle lumbalgia twenty days following his failed endovascular retrograde recanalization of the right iliac
artery, followed by a surgical femoral-femoral left-to-right by-pass graft.
Case Presentation:
Computer tomography angiography (CTA) revealed a left-sided 18 mm large pseudoaneurysm (PA) at the level of L5 lumbar vertebrae adjacent to
the aorta. This lumbal artery originated from the false lumen of the known chronic infrarenal aortic dissection. Within a single session, the
pseudoaneurysm was treated by percutaneous nonadhesive liquid embolic agent (NALEA - Onyx 34) embolization under CT-fluoroscopy
guidance. Follow-up imaging showed complete occlusion of the PA.
Conclusion:
This case shows the first usage of Onyx as a liquid embolic agent for this complication.
