「脈管」とは動脈・静脈およびリンパ管の総称であり，動脈と静脈を「血管」と称している．血管疾患には動脈疾患（脳・頸動脈，大動脈，冠・腹部・腎・末梢などの疾患）と静脈疾患（深部静脈血栓症など）がある．近年では動脈硬化性疾患の増加に伴い，無（低）侵襲的に動脈疾患を診断する方法などが注目され関心も高まってきた．動脈は全身に分布するため，全身の臓器とともに，動脈疾患の診断では動脈の特性やその特異性に注目する必要がある．本稿の目的は，高齢化や生活習慣病（糖尿病，脂質異常症，高血圧症，喫煙，肥満など）と関連し増加傾向にある動脈硬化疾患である「大動脈・末梢動脈病変」の超音波検査による標準的な評価方法を提示することである．それぞれの疾患を周知し，その診断基準に応じて確定診断をすることが必要である．

“Vessel” is a generic term for arteries, veins, and lymphatic vessels, and arteries and veins are called “blood vessels.” Vascular disease is comprised of arterial disease (diseases of cerebral/carotid arteries, aorta, and arteries in the abdomen/kidney/periphery, etc.) and venous disease (e.g., deep venous thrombosis). With an increase in arteriosclerotic disease in recent years, methods for diagnosing arterial disease that are noninvasive and minimally invasive have been attracting more and more attention. Because arteries are located throughout the body, attention must be paid to all organs in the body as well as to the characteristics and specificity of arteries when diagnosing arterial disease. This report is aimed at providing a standard method for ultrasound assessment of “aortic and peripheral arterial lesions,” which are forms of arteriosclerosis that are on the rise in association with aging and lifestyle-related diseases (e.g., diabetes mellitus, dyslipidemia, hypertension, smoking, obesity). We have to know the details of vascular diseases and examine them by vascular ultrasound according to the standard method.
