Coil embolisation

What is coil embolisation? This is a form of treatment which requires the use of a catheter (slim tube), x-rays and ultrasound. These x-rays and ultrasound act as a guide for the specialist as he/she inserts the catheter into the affected vein.

Coil embolisation procedure

The procedure involves the insertion of a catheter into the problematic vein in the back of the calf muscle or the leg. This catheter contains a small length of coil, made from platinum which is then placed into the vein.

A measure of alcohol is injected into the vein at the same time the catheter is removed. This alcohol acts as an irritant on the inner layer of the vein which forces it to close. This closure results in a scar.

Advantages of coil embolisation

This procedure is minimally invasive with no risk of scarring or infection on the outside of the body. The only scarring that occurs is within the affected vein.

Note: scarring and infection are side effects of surgery due to trauma occurring as a result of this invasive procedure.

It does not require a general anaesthetic which means no time off work due to sickness, dizziness or tiredness. This also means a quicker recovery time and improved success rates.

Disadvantages of coil embolisation

There are a few disadvantages to this procedure which include the simple fact that it is not suited to every case of varicose veins.

There is a small risk of bruising around the area where the catheter has been inserted.
