Endovenous Ablation: Indications and Risks

Endovenous ablation is a new method for treating varicose veins. This procedure has the advantage of being less painful and faster recovery time compared to the other techniques with the same outcome.

Vein Ablation Procedure

This procedure can be performed under general anaesthesia or local anaesthesia. Your surgeon will insert a thin tube called a catheter into a vein in the affected area under the guidance of an ultrasound probe. This is generally done below the knee or from the ankle. Different modalities can be used for ablation of the incompetent vein.

• Endovenous Laser Ablation (EVLA): with the use of laser, transmitted through a glass fibre, heat is generated at the tip of the fibre which caused the incompetent vein to collapse permanently.
• Radiofrequency ablation (RFA): an electromagnetic current is used to generate heat which causes a permanent closure of the vein.
• Ultrasound-guided foam sclerotherapy: your surgeon introduces a sclerosing agent, like sodium tertadecayl sulphate, into the vein which causes the cells to die and initiates a process that leads to the collapse of the vein.

Indications for Vein ablation

This procedure is suggested to individuals with varicose veins i.e. for individuals whose veins have incompetent valves, which when left untreated may lead to non-healing leg ulcers and discolouration of the skin. This procedure reduces complications from the venous disease.

Preparation for Vein Ablation

Before the procedure, your doctor would like to order a battery of tests to assess your fitness. You might also be asked to stop taking some medications in preparation for the surgery. Your doctor would also like to know about any past history of reaction to an anaesthetic.

Complications of Vein Ablation

Endovenous ablation carries fewer complications compared to other procedures. You may experience pain and discolouration of skin at the site of the procedure. Rarely, you may have a tingling sensation in the calf.

Recovery after Vein Ablation

You may be allowed to return home a few hours after the procedure. It is advised to arrange for someone to drive you home. Your doctor will advise you to avoid strenuous activities for some time. Keep the wound site clean and dry. You will be advised to keep you leg elevated when at rest.
