Overview
Non-surgical treatments include sclerotherapy, elastic stockings, elevating the legs, and exercise. The traditional surgical treatment has been vein stripping to remove the affected veins. Newer surgical treatments are less invasive (see radiofrequency ablation) and are slowly replacing traditional surgical treatments[1]. Since most of the blood in the legs is returned by the deep veins, and the superficial veins only return about 10%, they can be removed or ablated without serious harm.[2]
Medical Therapy
Conservative treatment
The symptoms of varicose veins can be controlled to an extent with the following:
- Elevating the legs often provides temporary symptomatic relief.
- "Advice about regular exercise sounds sensible but is not supported by any evidence."[3]
- The wearing of graduated compression stockings with a pressure of 30–40 mmHg has been shown to correct the swelling, nutritional exchange, and improve the microcirculation in legs affected by varicose veins.[4] They also often provide relief from the discomfort associated with this disease. Caution should be exercised in their use in patients with concurrent arterial disease.
The symptoms of varicose veins can be controlled to an extent with either of the following:
- Anti-inflammatory medication such as ibuprofen or aspirin can be used as part of treatment for superficial thrombophlebitis along with graduated compression hosiery – but there is a risk of intestinal bleeding. In extensive superficial thrombophlebitis, consideration should be given to anti-coagulation, thrombectomy or sclerotherapy of the involved vein.
- Diosmin 95 is a dietary supplement distributed in the U.S. by Nutratech, Inc. The U.S. Food and Drug Administration does not approve dietary supplements, and concluded that there was an "inadequate basis for reasonable expectation of safety." [5] [6]

Non-surgical treatment
Sclerotherapy
A commonly performed non-surgical treatment for varicose and "spider" leg veins is sclerotherapy. It has been used in the treatment of varicose veins for over 150 years.[7] Sclerotherapy is often used for telangiectasias (spider veins) and varicose veins that persist or recur after vein stripping.[8][9]
Sclerotherapy can also be performed using microfoam sclerosants under ultrasound guidance to treat larger varicose veins, including the greater and short saphenous veins.[10][11] A study by Kanter and Thibault in 1996 reported a 76% success rate at 24 months in treating saphenofemoral junction and great saphenous vein incompetence with STS 3% solution.[12] A Cochrane Collaboration review[13] concluded sclerotherapy was better than surgery in the short term (1 year) for its treatment success, complication rate and cost, but surgery was better after 5 years, although the research is weak.[14]
A Health Technology Assessment found that sclerotherapy provided less benefit than surgery, but is likely to provide a small benefit in varicose veins without reflux.[15] Complications of sclerotherapy are rare but can include blood clots and ulceration. Anaphylactic reactions are "extraordinarily rare but can be life-threatening," and doctors should have resuscitation equipment ready.[16] There has been one reported case of stroke after ultrasound guided sclerotherapy when an unusually large dose of sclerosant foam was injected.
Endovenous laser and radiofrequency ablation
The Australian Medical Services Advisory Committee (MSAC) in 2008 has determined that endovenous laser treatment for varicose veins "appears to be more effective in the short term, and at least as effective overall, as the comparative procedure of junction ligation and vein stripping for the treatment of varicose veins."[17] It also found in its assessment of available literature, that "occurrence rates of more severe complications such as DVT, nerve injury and paresthesia, post-operative infections and hematomas, appears to be greater after ligation and stripping than after EVLT". Complications for endovenous laser treatment include minor skin burns (0.4%)[18] and temporary paresthesia (2.1%).[18] The longest study of endovenous laser ablation is 39 months.
-
Varicose veins after EVLT
Two prospective randomized trials found speedier recovery and fewer complications after radiofrequency obliteration (AKA radiofrequency ablation) compared to open surgery.[19][20] Myers[21] wrote that open surgery for small saphenous vein reflux is obsolete. Myers said these veins should be treated with endovenous techniques, citing high recurrence rates after surgical management, and risk of nerve damage up to 15%. In comparison, radiofrequency ablation has been shown to control 80% of cases of small saphenous vein reflux at 4 years, said Myers. Complications for radiofrequency ablation include burns, paresthesia, clinical phlebitis, and slightly higher rates of deep vein thrombosis (0.57%) and pulmonary embolism (0.17%). One 3-year study compared radiofrequency, with a recurrence rate of 33%, to open surgery, which had a recurrence rate of 23%.
Endovenous laser and radiofrequency ablation require specialized training for doctors and expensive equipment. Endovenous laser treatment is performed as an outpatient procedure and does not require the use of an operating theater, nor does the patient need a general anesthetic. Doctors must use ultrasound during the procedure to see what they are doing. Some practitioners also perform phlebectomy or ultrasound guided sclerotherapy at the time of endovenous treatment. Follow-up treatment to smaller branch varicose veins is often needed in the weeks after the initial procedure.
