From: Clinical experience with a shape memory polymer peripheral vascular embolisation plug: a case series
Case 4. a Pre-embolisation DSA imaging of a type II endoleak into the thoracic aorta following TEVAR. b Intraprocedural DSA imaging following delivery of a 12 mm diameter shape memory polymer plug into the 10 mm diameter left subclavian artery. Arrows indicate the anchor coil and proximal marker. Shape memory polymer is radiolucent but is between the anchor coil and proximal marker. c Contrast injection following deployment of the plug. A small endoleak is still present. It should be noted that although complete occlusion ultimately occurs, it may take 10–20 min to occur. d Preprocedural CTA shows the type II endoleak. e Six-week follow-up CTA confirmed no recurrence of the type II endoleak. Arrows indicate the device anchor coil and proximal marker
