Varicose Veins

Leg Veins
The veins of the lower extremity are subdivided, into two sets, superficial and deep; the superficial veins are placed underneath the skin; the deep veins within the muscle fascia. Both sets of veins are provided with valves.
The superficial veins of the lower extremity are the great and small  saphenous veins, the accessory veins  and their tributaries. Perforators connect superficial to deep veins.
The great saphenous vein is
the longest superficial vein in the body, begins in the medial marginal vein of the dorsum of the foot and ends in the common femoral vein about 3 cm. below the inguinal ligament. 
The small saphenous vein  begins behind the lateral malleolus and often ends in the popliteal vein,
 behind the knee.

Veins serve to return less-oxygenated blood from organs to the heart; for this purpose, they have one-way flaps called venous valves that prevent blood from flowing back excessively and pooling in the legs due to gravity.

Venous Insufficiency
When valves become floppy, they are unable to keep the blood from returning back down into the leg and allow downward, prolonged reversed flow. Venous insufficiency can be caused by progressive valvular incompetence in the superficial or deep venous system or both, or be the consequence of an episode of venous thrombosis (clot in the leg vein). In these instances  venous blood refluxes backward down the veins causing increase in leg vein pressure. 
Untreated venous insufficiency in the deep or superficial system causes  progressive symptoms including one or a combination of symptoms such as  varicose veins, pain, swelling, skin changes, and tissue breakdown.

Varicose Veins
Prominent, large, tortuous (Varicose) leg veins are an expression of venous infufficiency. In the United States, most studies demonstrate varicose reflux in about 40% of the population, most commonly women (72% of women aged 60-69 years).
Varicose veins are not just an esthetic problem, they are associated with symptoms such as:
  • Heaviness
  • Restless legs
  • Leg fatigue
  • Burning, numbness
  • Swelling
  • Throbbing
  • Cramping
  • Aching
  • Itching
  • Skin discoloration
  • Eczema

Possible complications of chronic venous insufficiency include: chronic nonhealing leg ulceration, superficial thrombophlebitis, deep venous thrombosis (blood clots) and pulmonary embolism, bleeding varices.
Besides, a number of patients with complicated varicose veinshave a significant impairment of their quality of life, sometimes with loss of working days due to hospitalizations for the complications of their advanced chronic venous disease. Risk factors for the development and progression of varicose veins may include:

- Genetic predisposition
- Female gender
- Older age
- Obesity
- Pregnancies
- Prolonged standing
- Previous episode of venous thrombosis


A precise diagnosis is very important before any vein treatment.
Vascular Ultrasound provides the most accurate initial diagnosis and is the basis for targeted treatment for varicose veins.
A vascular technologist usually performs the procedure in an out-patient setting or to assist with procedures such as radiofrequency vein ablation. 
A clear gel is applied to the area of the body being studied to help visualization of the veins. The sonographer then presses the transducer firmly against the skin and sweeps it back and forth over the area o interest. Superficial and deep leg veins are visualized and tested for disease such as valvular incompetence and blood clots.
The results are instant and reported by the vascular technologist to the physician, who supervises the technologist and is responsible for the final report.    
  • Vascular ultrasound scanning is non-invasive (no needles or injections) and is painless.
  • Ultrasound imaging uses no ionizing radiation.  
  • Ultrasound causes no health problems and may be repeated as often as is necessary.
  • There are no known harmful effects on humans.


A Vascular Surgeon is the only medical specialist trained to address vascular disease in its entirety 
A Vascular Surgeon formal training includes more experience in vein treatment than any other specialty. It spans from the diagnosis and treatment of superficial as well as deep venous incompetence, which may need anything from an office-based procedure to an hospital admission for complicated cases (i.e. leg ulcer with cellulitis, complicated deep venous thrombosis) or surgery (venous reconstructions, stripping, bypasses, stents, caval filters). Moreover, sometimes a patient with a venous condition has a concomitant arterial condition, such as peripheral arterial occlusive disease, which needs to be addressed first, and which will not be able to treated along with the venous condition by any other medical specilaty.

Use of compression stockings is almost always indicated. In addition, office-based treatments for Varicose and Spider Veins performed at SCOVAS include:


This procedure is performed to treat  spiders, varicose veins, perforating veins, venous branches and, occasionally, the saphenous veins. Liquid or foam sclerotherapy can be injected depending on the case, with or without the aid of Ultrasound. No anesthesia is needed and return to normal activities is immediate.


This minimally-invasive technique is utilized to eliminate the saphenous veins as well at perforating veins and larger venous branches. Only local anesthesia is required, and just a tiny incision is performed at the knee level. After the vein has been treated by heat (Closure), glue (Venaseal), pharmacomechanical (Clarivein), foam (Varithena). The patients can walk immediately and resume their normal activities.
