The Influence of Collagen Impregnation of a Knitted Dacron Patch Used in Carotid Endarterectomy

In selected populations, carotid endarterectomy (CEA) reduces long-term stroke risk. Studies have shown increased risk of restenosis with use of a collagen-impregnated Dacron patch compared to a PTFE patch. There is concern that collagen-impregnation may initiate thrombosis or promote restenosis due to platelet activation. We performed a retrospective analysis of our CEA experience with routine patching using knitted Dacron patches with (Hemashield) and without (Sauvage) collagen-impregnation.
