A surgical procedure in which a portion of an artery is removed or excised to treat disease or repair damage.
From 'arteria' (artery) combined with '-ectomy' (surgical removal), following the established medical convention for naming surgical procedures that became standardized in the late 1800s.
The '-ectomy' ending became the universal code for 'surgical removal'—appendectomy, tonsillectomy, arteriectomy—it's like a prefix that instantly tells you 'something is being cut out'!
