A common condition, varicose veins are both a cosmetic concern and a potential health problem.

Varicose veins are essentially distended, swollen veins present in the subcutaneous layer. Often the cause of much pain and discomfort, this condition occurs in the leg when the  valves within a vein begin to fail. Since blood is pumped back to the heart against gravity, these one-way valves are required to stop blood pooling in the veins.

When it comes to treating this condition, the required procedure will ultimately depend on the severity: small varicose veins can be treated via sclerotherapy, while larger, more problematic ones require laser therapy or surgery.

Wherever possible, Mr. Venu Bhamidi will opt to perform varicose vein laser therapy rather than surgery, as it is the preferred less invasive option.


Endovenous thermal ablation is a minimally invasive technique used to obliterate the major problematic vessels causing the varicose veins. The veins can be thermally ablated using either radiofrequency or laser energy with both techniques having similar results. The procedure is done in an office setting with local anaesthetic with the whole process taking 45-60 minutes from start to finish. Both techniques (RFA and Laser) use a catheter/fibre that is inserted into the vein under ultrasound guidance and advanced to top of the problematic vein. Once this is in place, local anaesthetic is delivered around the vein to make the area numb. The local anaesthetic not only helps with preventing pain, it also allows the vein to shrink down onto the catheter and protects the skin surface from being affected by the heat. The catheter then deliver thermal energy to heat the vein and damage the vein wall which causes it to collapse, shrink and finally disappear over a few weeks to months. This is our preferred method of treatment of large veins and avoids surgery, incisions and prolonged time off work, with patients often returning to a day or so after the procedure.

The VenaSeal system improves blood flow by sealing–or closing–the diseased vein. The system delivers a small amount of a specially formulated medical adhesive to the diseased vein. The adhesive seals the vein and blood is rerouted through nearby healthy veins. The treated superficial veins close immediately and stay closed. Blood flows through nearby healthy veins and symptoms improve.  The VenaSeal system and thermal energy (radiofrequency ablation; RFA) treatments have similar clinical results in the short to medium term. The most common effect that patients notice after Venaseal is phlebitis (i.e., inflammation of a vein). Phlebitis occurs a little more frequently in VenaSeal-treated patient compared to RFA-treated patients.
