Embolisation for bleeding

What is the embolisation procedure for bleeding?

Embolisation is a minimally invasive treatment which uses materials to block the affected vessel and so stop bleeding. There are a number of possible causes of bleeding severe enough to require this treatment, including trauma, blood clotting disorders, infections, anatomical defects and tumours.

 

How does the procedure work?

The procedure aims to stop blood flowing to the source of the bleeding whilst also preserving the blood flow to the surrounding area.

The interventional radiologist will usually insert a 2-3 mm tube into your groin and will guide this to the affected blood vessel. They will then insert small resin particles (microparticles), glue or small metal spirals (coils) into the bleeding vessel or vessels. This causes the vessel or vessels to become blocked and so stops the bleeding.

 

Why perform it?

The main reason for treating bleeding is that if too much blood is lost, the patient may go into life-threatening shock.

 

What are the risks?

Minor risks include bruising in the groin. More significant risks include the possibility that microparticles, glue or the coils may move to other areas of the body and block other artery branches.
