Arteriosclerosis obliterans refers to the narrowing of the arteries due to the buildup of cholesterol and plaque, which eventually leads to the blockage of blood flow. Synonyms for arteriosclerosis obliterans include peripheral vascular disease, atherosclerosis, arterial occlusive disease, and vascular stenosis. In some cases, it may also be referred to as lower extremity arterial disease or peripheral arterial disease. These terms are all used to describe the same condition, with similar symptoms, causes, and treatment options. It is important for individuals at risk of arteriosclerosis obliterans to maintain a healthy lifestyle and receive regular medical check-ups to prevent complications and manage symptoms.
