What is the term for the narrowing or blockage of blood vessels in the leg?

The term for the narrowing or blockage of blood vessels in the leg is peripheral arterial disease. This condition occurs when the arteries that supply blood to the limbs, typically the legs, become narrowed or blocked, leading to reduced blood flow. This can result in symptoms such as pain and cramping during physical activity, as well as potential complications like wounds that do not heal properly.

Understanding this condition is important in the context of overall cardiovascular health, as it can signify systemic issues related to blood circulation. While coronary artery disease refers specifically to the narrowing of arteries that supply blood to the heart, and atherosclerosis is the process that leads to the buildup of plaques in the arteries throughout the body including peripheral arteries, peripheral arterial disease specifically targets blood flow issues in the extremities. Deep vein thrombosis involves blood clots in the deep veins, which is a different vascular concern. Thus, peripheral arterial disease is the most precise term for the blockage or narrowing of blood vessels in the leg specifically.
