endoleak
Pronunciation: EN-doh-leek
Persistent blood flow into aneurysm sac after endovascular repair.
Full Definition
Continued perfusion of an aneurysm sac following endovascular stent-graft placement, classified into five types based on source and mechanism. Type I endoleaks involve inadequate seal at proximal or distal attachment sites, Type II involves retrograde flow from branch vessels, and Type III indicates graft defects. Proper classification is essential for determining appropriate treatment strategies and surveillance protocols.
Usage
Usage note: Always specify type (I-V) when documenting endoleaks in clinical reports.
