Veins are blood vessels that carry blood from your body’s tissues to your heart. The heart pumps blood to your lungs to pick up oxygen. The oxygen-rich blood flows through tiny blood vessels called capillaries, where it gives up its oxygen to the body’s tissues. Your blood then returns to your heart through your veins to pick up more oxygen. Veins have one-way valves that help keep blood flowing toward your heart. If your valves are weak or damaged, blood can back up and pool in your veins. This causes the veins to swell and can lead to varicose veins.
Varicose veins are abnormal, dilated blood vessels caused by a weakening in the vessel wall. They can look like swollen, twisted clusters of blue or purple veins under the skin. Varicose veins may be surrounded by thin, red capillaries known as spider veins (a group of tiny blood vessels located close to the surface of the skin).
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 (superficial veins). Deeper varicose veins can’t be seen but may cause the skin above them to become darker or hard.
Symptoms usually start before the age of 40 and may include:
Varicose veins are related to increased pressure in the leg veins or defective valves in the veins. They form when healthy vein walls swell and cause blood to back up and collect inside the vein. Normally, blood flows through the vein in one direction toward the heart. Varicose veins create new paths for blood flow.
There are several factors that increase your risk of getting varicose veins:
Topical steroids, trauma or injury to the skin, previous venous surgery and exposure to ultra-violet rays may also increase your risk of varicose veins.
Your doctor will examine you and check your legs while you are standing. You may need an ultrasound exam (Doppler scan) to check the blood flow in the veins near the skin’s surface and the deep veins.
Not everyone needs treatment for varicose and spider veins. Call your doctor if:
Varicose veins can be harmful to your health if they lead to:
Complications are more likely when varicose veins are due to a problem or disease in the deep veins or the perforating veins that connect the deep and superficial veins, such as deep vein thrombosis or chronic venous insufficiency. Ask your doctor about your risk of developing any of these conditions.
The goals of treatment are to reduce symptoms and reduce the risk of complications. Since not all patients need medical treatment, the goal of treatment may be to improve the appearance of the affected areas.
Wearing properly fitting support hose(also called compression stockings) is the most conservative treatment approach, especially when the veins don’t cause symptoms. It is important to talk to your doctor about the right compression level for you.
Other conservative treatment methods include:
Other treatment options include sclerotherapy, laser and light therapy, minimally invasive procedures and surgery.
Sclerotherapy is a nonsurgical treatment that involves injecting a chemical solution into the veins to make them collapse.Because the veins can no longer carry blood, they will eventually disappear. Circulation improves because the work of carrying the blood is shifted to nearby healthy blood vessels.It usually takes 1 to 3 sessions for the treatment to be effective, and treatments should be spaced 4 to 6 weeks apart. Upto 40 veins can be treated during each session. Once treated, the veins disappear over a period of six months and do notreappear. However, sclerotherapy treatment cannot stop new varicose or spider veins from developing.The only discomfort during sclerotherapy is the sensation of small needle pricks. After treatment, you will wear medical-grade support stockings for 2 to 4 weeks. Walking and moderate exercise can help you recover faster.Temporary reactions to the treatment can include slight swelling of the leg or foot, minor bruising, itching, redness and mild soreness. Rare complications include the development of telangiectasias – small clusters of red blood vessels, skin ulcers, and brown pigmentation around the treated vessels.
Laser and pulse-light therapy are used to heat the blood vessel to shrink it. Laser therapy is most effective for the treatment of small varicose veins. Laser therapy may be used as an additional treatment after sclerotherapy, endovenous procedures, or surgery of larger veins. It may take several treatments, spaced at six-week intervals, for treatment to be effective.
High-intensity, pulsed light (photoderm or light therapy) is another treatment option. It is different than laser and pulse-light therapy because it uses a spectrum of light instead of a single wavelength. It can be used to shrink small spider veins, certain varicose veins and vascular birthmarks. This treatment may be recommended if sclerotherapy or laser therapy is not effective.
Endovenous thermal ablation uses lasers or radio waves to create heat to close off a varicose vein. Your doctor makes a tiny cut in your skin near the varicose vein and inserts a small tube called a catheter into the vein. A device at the tip of the tube heats up the inside of the vein and closes it off. You will be awake during this procedure, but the area around the vein will be numbed. You usually can go home the same day as the procedure.
Surgery may be the best treatment if you have varicose veins that are severe or cause problems such as bleeding, pain or swelling. Several surgical treatments are available. Your doctor can help you understand your options and the risks and benefits of each procedure. Surgical treatments are performed by a vascular specialist in either a hospital or outpatient center.
Ligation and stripping are often done at the same time. Vein ligation is a minor procedure that involves cutting and tying off the problem veins. Most patients recover in a few days and can get back to their normal activities.Stripping is the surgical removal of larger varicose veins through two small incisions. Stripping is a more extensive procedure than ligation. It can take up to 10 days to recover and usually causes bruising that lasts several weeks.
Many insurance companies cover the cost of treating varicose veins, but generally not spider veins. Please check with your insurance company before considering a particular treatment option.
