EC-IC Bypass in the COSS study
EC-IC Bypass surgery involves taking an artery from the scalp outside the skull, making a small hole in the skull, and then connecting the scalp artery to a brain artery inside the skull. In this way, the blockage of the carotid artery in the neck is bypassed and more blood can flow to the brain.
