Vascular disease includes any condition that affects the circulatory system. As the heart beats, it pumps blood through a system of blood vessels called the circulatory system. The vessels are elastic tubes that carry blood to every part of the body. Arteries carry blood away from the heart while veins return it.
Vascular disease ranges from diseases of your arteries, veins, and lymph vessels to blood disorders that affect circulation. The following are conditions that fall under the category of vascular disease.
Peripheral Artery Disease
Like the blood vessels of the heart (coronary arteries), your peripheral arteries (blood vessels outside your heart) also may develop atherosclerosis, the build-up of fat and cholesterol deposits, called plaque, on the inside walls. Over time, the build-up narrows the artery. Eventually the narrowed artery causes less blood to flow and a condition called "ischemia" can occur. Ischemia is inadequate blood flow to the body's tissue.

Aneurysm
An aneurysm is an abnormal bulge in the wall of a blood vessel. They can form in any blood vessel, but they occur most commonly in the aorta (aortic aneurysm) which is the main blood vessel leaving the heart. The two types of aortic aneurysm are:
Small aneurysms generally pose no threat. However, one is at increased risk for:
Renal (Kidney) Artery Disease
Renal artery disease is most commonly caused by atherosclerosis of the renal arteries (see above). It occurs in people with generalized vascular disease. Less often, renal artery disease can be caused by a congenital (present at birth) abnormal development of the tissue that makes up the renal arteries. This type of renal artery disease occurs in younger age groups.
Raynaud's Phenomenon (Also Called Raynaud's Disease or Raynaud's Syndrome)
Raynaud's phenomenon consists of spasms of the small arteries of the fingers and sometimes the toes, brought on by exposure to cold or excitement. Certain occupational exposures bring on Raynaud's. The episodes produce temporary lack of blood supply to the area, causing the skin to appear white or bluish and cold or numb. In some cases, the symptoms of Raynaud's may be related to underlying diseases (ie, lupus, rheumatoid arthritis, scleroderma).

Buerger's Disease
Buerger's disease most commonly affects the small and medium sized arteries, veins, and nerves. Although the cause is unknown, there is a strong association with tobacco use or exposure. The arteries of the arms and legs become narrowed or blocked, causing lack of blood supply (ischemia) to the fingers, hands, toes, and feet. Pain occurs in the arms, hands and, more frequently, the legs and feet, even when at rest. With severe blockages, the tissue may die (gangrene), requiring amputation of the fingers and toes.
Superficial vein inflammation and symptoms of Raynaud's occur commonly in patients with Buerger's disease.
Peripheral Venous Disease
Veins are flexible, hollow tubes with flaps inside called valves. When your muscles contract, the valves open and blood moves through the veins. When your muscles relax, the valves close, keeping blood flowing in one direction through the veins.
If the valves inside your veins become damaged, the valves may not close completely. This allows blood to flow in both directions. When your muscles relax, the valves inside the damaged vein(s) will not be able to hold the blood. This can cause pooling of blood or swelling in the veins. The veins bulge and appear as ropes under the skin. The blood begins to move more slowly through the veins, it may stick to the sides of the vessel walls and blood clots can form.
Varicose Veins
Varicose veins are bulging, swollen, purple, ropy veins, seen just under your skin, caused by damaged valves within the veins. They are more common in women than men and often run in families. They can also be caused by pregnancy, being severely overweight, or by standing for long periods of time. The symptoms of varicose veins include:

Blood Clots In the Veins
Blood clots in the veins are usually caused by:
There are many types of blood clots that can occur in the veins:
Blood Clotting Disorders
Blood clotting disorders are conditions that make the blood more likely to form blood clots in the arteries and veins. These conditions may be inherited (congenital, occurring at birth) or acquired during life and include:
