Varicose vein ablation is a minimally invasive treatment option for varicose veins, a common condition where veins, usually in the legs, become enlarged, swollen, and often twisted. This condition not only affects the appearance of the legs but can also cause discomfort, pain, and sometimes more serious health problems. In this blog, we will explore what varicose vein ablation involves, its types, benefits, risks, and what to expect before, during, and after the procedure,Varicose Vein Treatment: Endovenous Laser Therapy.

What is Varicose Vein Ablation?

Varicose vein ablation is a medical procedure designed to close off varicose veins, improving blood flow and reducing symptoms. Unlike surgical stripping, ablation is less invasive and can be performed in a doctor’s office or outpatient setting. The procedure works by applying heat, laser light, or chemical substances to the inside of the vein, causing it to close and eventually be reabsorbed by the body.

Types of Varicose Vein Ablation

There are primarily two types of varicose vein ablation: thermal and non-thermal techniques.

  • Thermal Ablation: This involves using heat to close the vein. The two main types are:
  • Endovenous Laser Ablation (EVLA): A laser fiber is inserted into the vein, and laser energy is used to heat and close the vein.
  • Radiofrequency Ablation (RFA): Similar to EVLA, but uses radiofrequency energy to generate heat.
  • Non-Thermal Ablation: These methods do not use heat. Examples include:
  • Mechanochemical Ablation (MOCA): Combines mechanical damage with a chemical sclerosant to close the vein.
  • Cyanoacrylate Adhesive (VenaSeal™): A medical adhesive is used to seal the vein.

Benefits of Varicose Vein Ablation

Varicose vein ablation offers several benefits over traditional surgical methods:

  • Minimally invasive with no need for general anesthesia.
  • Reduced recovery time and minimal discomfort.
  • Immediate return to daily activities, in most cases.
  • High success rate and low recurrence of varicose veins.

Risks and Complications

While varicose vein ablation is generally safe, it can carry risks, such as:

  • Infection at the puncture site.
  • Deep vein thrombosis (DVT).
  • Nerve damage, though this is rare.
  • Skin burns or discoloration, particularly with thermal ablation methods.

Before the Procedure

Preparation typically involves:

  • A detailed medical history review and physical examination.
  • An ultrasound to map the veins and plan the procedure.
  • Instructions to avoid certain medications or supplements that can increase bleeding risk.

During the Procedure

The procedure usually takes about an hour and involves:

  • Local anesthesia to numb the treatment area.
  • A thin catheter or probe inserted into the vein through a small incision.
  • Application of the chosen ablation technique to close the vein.
  • Removal of the catheter and application of a bandage or compression stocking.

After the Procedure

Post-procedure care is crucial for a successful recovery:

  • Walking immediately after the procedure to encourage blood flow.
  • Wearing compression stockings for a specified period to support vein closure.
  • Avoiding prolonged standing or sitting, heavy lifting, and strenuous exercise for a short time.
  • Follow-up ultrasound to ensure the vein has closed properly.


Varicose vein ablation is a safe, effective, and minimally invasive treatment option for those suffering from varicose veins. It offers a quick recovery, minimal discomfort, and a high success rate. If you’re considering this procedure, consult with a vascular specialist to discuss the best treatment option for your specific condition.
