Popis: Patching after endarterectomy, especially carotid artery surgery, is a common procedure to repair and close the surgical site. Both synthetic and natural materials can be used, but saphenous vein is preferred due to its greater long-term patency. In situations where it is not possible to use the saphenous vein, both Dacron and expanded polytetrafluoroethylene (ePTFE) patches have been used successfully. Expanded PTFE patches are readily available, soft and pliable, have excellent biocompatibility and do not require preclotting prior to implantation. Comparison of two types of ePTFE patches versus natural vessel show that they have more than adequate properties for their intended use.
