Varicose veins are very common with estimates ranging as high as 15 to 20% of the general population. In patients over the age of 50 years, varicose veins are estimated to be present in as high as 50% of the general population. This age relationship tends to be due to the atrophy of the muscle as we age resulting in loss of muscle tone and less support for the vein. The superficial veins of the leg are particularly predisposed to increased pressure due to lack of support on all sides of their walls.


  • Deep blue and red visible veins on the leg and foot
  • Often no pain described
  • If painful, pain increases with duration of time spent standing
  • Swelling of the distal 1/3 of the lower leg
  • Changes in the skin causing peeling and redness
  • Ulceration of the medial ankle


The venous system of the leg consists of three categories of veins; superficial, perforating and deep. Superficial and deep veins are lined with valves. Valves are varicosity of the footsmall cups that allow blood to flow in one direction (uni-directional). Venous flow begins in the distal, superficial veins, into the perforating veins and finally to the deep veins with return to the heart. The muscles of the legs aid in compressing the veins of the leg, pushing the blood through the veins to the heart. Defects in the valves allow blood to flow in a reverse direction creating back pressure on the wall of the vein. This back pressure is called venous hypertension.  If venous hypertension is sufficient to damage the supportive wall of the vein, the vein will change in shape to become tortuous and dilated creating what we know as a varicose vein. Telangectasia are very similar to varicose veins and are the small visible superficial veins often referred to as spider veins.

Varicose veins and telangectasia account for more than 90% of overall venous disease. The importance of treating varicose veins lies in the factvenous_ulcer_of_the_leg that patients with varicosities are more predisposed to the formation of emboli (blood clots) within the varicosity. Emboli can have significant sequella including pulmonary embolus (blood clot to the lung) or myocardial infarction (heart attack). Another common problem associated with chronic venous disease of the legs is edema (swelling). Chronic edema of the legs due to venous hypertension may lead to venous stasis dermatitis, cellulitis, venous ulcers and the inability to stand or walk.

Causes and contributing factors

The causes of varicose veins and telangectasia are many, but the single most common contributing factor is genetic. Most of the contributing factors implicated in causing varicose veins do so by creating a back pressure on the flow of blood from the legs into the pelvis. These include obesity, prolonged periods of standing, pregnancy or abdominal tumors.

Differential diagnosis

The differential diagnosis for varicose veins includes;

Peripheral arterial disease
Tumor of the leg


TelangectasiaAt the onset of varicose veins or telangectasia, support by leg compression is essential to control the progression of the damage to the vessel wall. In early cases, support may be a simple as OTC support hose. As the damage to the vessel increases, support will require prescription support hose. Prescription support hose are made on a case by case basis and require that the patient be measured for an exact fit.

Homeopathic medicine discusses nutritional support for healthy veins and varicose veins. Horse chestnut (Aesculus hippocastanum) has been used for years as a natural product known to promote the health of the vein wall. Other homeopathic remedies for varicose veins include white oak bark.

Sclerotherapy is a popular method used to treat telangectasia and small varicose veins. Sclerotherapy is performed in the office without the use of anesthesia. The chemicals used to perform sclerotherapy vary, but the most popular is 23% saline, or salt water. The concentrated salt solution scleroses the vein by dehydrating the cells of the vein wall. Compression is applied to the leg for several days following sclerotherapy to promote the ability of the sclerosing agent to complete its' job.  Although sclerotherapy is a permanent change to the vein, sclerotherapy needs to be performed every 3-5 years due to new telangectasia that form over time.

Several types of lasers are also to treat telangectasia. The draw back to the lasers are that they treat a very focused area compared to the injection methods of sclerotherapy. The laser's most appropriate use seems to be for touch-up sclero following an incomplete or partially successful injection.

Radiofrequency ablation is a popular office based technique use for large varicosities. The technique uses ultrasound to view the saphenous vein to guide the insertion of a small catheter from the knee to the groin. Radio-frequency energy is then used to destroy the lining of the vein. As the catheter is slowly removed, the destruction of the vein is performed to the insertion point above the knee. This technique can be completed in an office setting and patients can bear weight immediately follow surgery.  Use of support hose is recommended for a period of 10-14 days following the procedure.

In advanced cases of varicose veins, venous stripping may still be the treatment of choice for some vein specialists. Venous stripping is a surgical procedure, performed under general anesthesia.  But with the popularity and success of radiofrequency ablation, vein stripping is rarely recommended.
