I73: Other peripheral vascular diseases

The group of conditions known as "Other Peripheral Vascular Diseases" encompasses a variety of diseases that impact the blood vessels outside of the heart and brain. These conditions typically involve narrowing, blockage, or spasms in blood vessels. They may be caused by build-up of fatty deposits in the arterial wall (atherosclerosis), an inflammation of blood vessels (vasculitis), or blood clot formation (thrombosis). Notably, these diseases can affect any blood vessel, including those that supply blood to the arms, legs, and organs. Common symptoms can include pain, changes in skin temperature, color changes in the skin, and slower growth of hair or nails on the affected limb. However, some patients may also experience no symptoms until the disease has significantly progressed. The progression of these conditions can lead to serious health issues like heart attack or stroke if the blood supply to those vital organs is compromised.
