Vascular anatomy is the study of the structure and arrangement of blood vessels, including arteries, veins, and capillaries, within the body. Understanding vascular anatomy is essential for diagnosing and managing conditions such as aneurysms, thrombosis, and vascular malformations, as well as for performing surgical and interventional procedures safely. For example, detailed knowledge of coronary artery anatomy is crucial in treating ischemic heart disease and preventing complications during angioplasty.
