Laser Ablation of Varicose Vein

Varicose veins or varicosities are enlargement or dilation of veins with blood due to malfunctioning of the one-way valves in veins that prevent blood from flowing backward. Blood starts to collect in the veins rather than moving towards the heart leading to swollen, raised and painful veins. 
To treat varicose veins, experienced interventional radiologists, phlebologist, dermatologist or vascular surgeons at SRV Group of Hospitals perform image- guided, minimally invasive procedure like endovenous ablation. It uses radiofrequency or laser energy to burn and closes the varicose veins. A local anesthesia will be used and using ultrasound guidance, a catheter or vascular access sheath is inserted through the skin and positioned within the abnormal vein. Through the catheter, the laser fibre or radiofrequency electrode is inserted and the tip of the fibre or electrode is exposed by pulling the catheter back slightly. Local anesthetic is injected around the abnormal vein and laser or radiofrequency energy is applied as the catheter is slowly withdrawn. There is no need of sutures and opening in the skin is bandaged. Patient is advised to wear compression stockings for almost 14 days for recovery. Post ablation, the malfunctioning vein will shrink and scar down. It usually takes one hour to complete the procedure. 
The patient would be called for a follow up examination after one week to assess the treated vein and to check for adverse outcomes, if any. Endovenous laser ablation (EVLA) has a successful initial closure rate of 95–100%. The outcomes appear long-lasting, with a persistent closure rate after 10 years of 85–97%.
