頸動脈疾病(carotid artery disease) 是頸動脈狹窄或是阻塞。大多是因為粥狀動脈硬化所 形成，狹窄或阻塞造成大腦供應不足而缺氧，進一步可能會造成暫時性腦缺血發作或是中 風。治療包括生活型態的改變、藥物或是開刀。

Carotid artery disease is the narrowing or blockage of the carotid arteries. Carotid artery disease is caused by atherosclerosis, or hardening of the arteries. Narrowing or blockage of the carotid arteries can prevent blood from reaching parts of the brain. This lack of blood can cause shortages of oxygen that can result in transient ischemic attacks (TIAs), also called mini-strokes, or strokes. Treatment of carotid artery disease includes lifestyle changes, medications, or surgical procedures. (J Intern Med Taiwan 2017; 28: 206-212)
