Varicose Veins

Varicose veins are one of the common diseases seen in everyday life and present as large dilated blood vessels in the legs.  In a few people, the varicose veins are simply a cosmetic concern. But in others, they can present with pain, discomfort, bleeding, or an ulcer. Thanks to recent advances in interventional radiology, this disease can be easily treated using pinhole procedures.

Frequently Asked Questions

What are varicose veins?

The veins are the blood vessels that bring blood back from the body to the heart. In the lower limbs, there are two sets of veins, the superficial and the deep. The superficial group lies below the skin. Varicose veins are enlarged tortuous ugly-looking blood vessels beneath the skin. These usually protrude from the skin’s surface and have a “rope /worm” like appearance.

What causes varicose veins?

All veins have valves that allow the flow of blood to the heart and prevent backflow. When these valves do not function properly, the blood flows backward and causes enlargement of blood vessels.

Who suffers from varicose veins?

Varicose veins are quite common and affect up to 15-20% of the Indian population. Women are more likely to be affected by varicose veins than men because female hormones tend to relax the walls and valves of the veins. Patients that are obese and have spent long hours standing have a higher incidence of varicose veins. There is a vital genetic component as well.

What are the symptoms of varicose veins?

  1. Pain and heaviness in legs. 
  2. Skin discolouration.
  3. Leg edema.
  4. Can bleed or cause ulceration which can be pretty challenging to heal.

Can one prevent the varicose veins?

  1. If one starts early in life, varicose veins can be prevented. The primary preventive measure is to exercise and wear compression stockings.
  2. Elevation of the legs
  3. During pregnancy, one should always lie on the left side with the legs elevated on a pillow. This prevents the fetus from pressing on the blood vessels and decreases the chance of developing varicosities.
  4. Avoid standing for prolonged periods.
  5. Wear elastic support stockings.

What problems can occur if left untreated?

The varicose vein’s size is not related to complications, but the duration of the varicose vein is. The complications include:
1. Superficial thrombophlebitis – in this condition, the varicose vein is inflamed and tender. A clot is usually present in the vein.
2. Bleeding – even with minor trauma, the varicose vein may be associated with bleeding. Because the vein is under high pressure, the bleeding can be quite profuse.
3. Eczema – the skin around the vein may become dry and very itchy.
4. Skin pigmentation – this is brown staining of the skin around the ankle. It is due to the leakage of a small amount of blood from the veins into the skin.
5. Leg ulcers

How can varicose veins be diagnosed?

Varicose veins can usually be diagnosed by a simple physical examination. However, the cause of the varicose vein requires the use of Doppler ultrasound. This painless test assesses the blood vessels traveling close to the skin as well as to the bone.

What is the treatment for varicose veins?

The symptoms are initially treated with simple compression stockings. When symptoms from varicose veins do not improve with compression stockings or when patients develop complications, as mentioned earlier, they need further treatment. The conventional method of treatment is surgery (Stripping of veins), which is rarely done today. The latest technology of varicose vein removal in Interventional radiology departments are ablation and adhesive embolization (Pinhole techniques).

Pinhole Techniques

Ablation treatment

Ablation is a technique of blocking the blood vessel using radiofrequency / microwaves, delivered by a small wire with a special tip. This device is placed in the abnormally dilated vein through a 2mm skin incision in the leg. The probe delivers heatwaves. The heat energy released will destroy the walls of veins. This treatment causes complete occlusion of the vein in more than 90% of the patients, with dramatic improvement in their symptoms. This procedure can be done under local anesthesia. The process requires less than a 24hours hospital stay.

Adhesive embolization

This is a non-thermal non-tumescent method for varicose vein treatment. In this treatment, specialized glue is injected into the abnormal veins. This glue instantaneously obliterates the vein permanently, which takes away the symptoms caused by varicose veins. This procedure has several advantages. The method requires just one single injection. It requires a much shorter time, and there is no need for a compression stocking, enabling the patient to get back normal function immediately following the procedure.

Why pinhole techniques are preferred over surgery?

  • Outpatient procedure. 
  • No scars 
  • The procedure can be done under local anesthesia. 
  • Mobilization within an hour and Can resume routine activities for the next day. 
  • Decreased incidence of post-procedure complications and recurrence.
