The abnormal dilation or enlargement of an artery, often used interchangeably with arteriectasia to describe widened blood vessels.
Variant of arteriectasia using the Greek suffix '-ectasis' (dilation) instead of '-ectasia', both forms became standard in medical terminology during the 19th century.
Medical terminology often has multiple names for the same condition—both arteriectasia and arteriectasis describe the same thing, which can be confusing but shows how medical language evolved organically from different traditions!
