Varicose veins and spider veins videos (Dr. Joseph and Dr. Anton)

What are varicose and spider veins?

Varicose veins are abnormal, dilated blood vessels caused by a weakening in the vessel wall. They may appear as swollen, twisted clusters of blue or purple veins. Varicose veins are sometimes surrounded by thin, red capillaries known as spider veins (group of tiny blood vessels located close to the surface of the skin, also called telangiectasias).

Varicose and spider veins can appear anywhere, but most often appear on the legs and in the pelvic area. Most varicose veins develop near the surface of the skin.

Who gets varicose and spider veins?

Varicose veins are common and are usually not a sign of a serious medical problem. Varicose and spider veins are seen more often in women than in men. They become more prevalent with age and have been reported to affect from 30 to 50 percent of the adult population. The incidence varies depending on the group of people who are studied.

What causes varicose and spider veins?

Varicose veins occur when healthy vein walls become weak and the vein enlarges. Blood can “pool” or collect inside the vein. Varicose veins are related to increased pressure in the leg veins or defective valves in the veins.

The exact cause of varicose veins is unknown, but there are a number of factors that contribute to the development of varicose and spider veins. Risk factors for varicose and spider veins include:
