An 81-year-old man following a Whipple with pancreatic leak and a pseudoaneurysm arising from the superior aspect of the proximal superior mesenteric artery (arrow, a, b ). This was crossed and a balloon expandable covered stent was placed ( c ). Follow-up imaging demonstrated persistent filling (arrow, d ) and a type 1 endoleak was suspected. A microcatheter was advanced alongside the covered stent ( e ) and ethyl vinyl copolymer was injected. The proximal stent graft was dilated and the leak resolved.
