Varicose Veins

Most varicose veins aren't a serious medical problem, but they sometimes can lead to complications.

Complications can include:

• Bleeding from a varicose vein, which may occur without an injury or after an injury to the thin skin over the varicose vein. Bleeding can be heavy, but it can be controlled by elevating the leg and applying pressure to the area that is bleeding.
• Blood clots or inflammation (superficial thrombophlebitis), when a blood clot and inflammation develop in a small vein near the surface of the skin. Unlike blood clots in deep veins, clots in superficial veins rarely travel to the heart or lungs, where they could cause serious blockages.
• Dry, stretched, swollen, itching, or scaling skin.
• Thin, fragile, easily injured skin at or above the ankle.
• Open sores (ulcers), usually near the ankles.
• Skin color changes (stasis pigmentation) around the ankles and lower legs.
• Fungal and bacterial infections, which may arise from skin problems resulting from fluid buildup (edema) in the leg and increased risk of tissue infection (cellulitis).

Varicose veins most often are a result of problems in the superficial veins just under the skin. But they can happen along with problems or disease in the Reference deep veins Opens New Window and Reference perforating veins Opens New Window, which connect the deep and the superficial veins. Complications are much more common when varicose veins are caused by or linked with these deeper veins.
