CTICasesSubclavian Endoleak after Frozen Elephant Trunk
[...]. Subclavian Endoleak after Frozen Elephant Trunk. CTICases. Published January 26, 2019. https://str-case-explorer.pages.dev/c/6ttyz
Imaging findings
Postoperative CTA shows arch replacement with a frozen elephant trunk. There is a persistent contrast collection (endoleak) originating from the manual fenestration at the origin of the left subclavian artery. Intraoperative angiograms show successful exclusion of the leak using a covered Viabahn stent graft.
Key takeaways
Manual fenestration of frozen elephant trunk stent grafts to preserve the left subclavian artery can lead to localized endoleaks. These can be treated endovascularly with covered stent grafts.
