Refractory Epistaxis Embolization

Epistaxis embolization is a minimally invasive procedure in which the radiologist deliberately blocks blood vessels to stop the nosebleed.

When is the procedure recommended?

  • Treatment is recommended for patient's experiencing severe nosebleeds.
  • Epistaxis embolization aims to minimize the risk of the patient breathing in blood, which could cause drowning.
  • This treatment approach is much less invasive and does not require general anesthesia.

How is the procedure performed?

The procedure stops the blood flowing into the vessels, which causes the nosebleed. It also prevents blood from flowing into the area around the affected vessels.

Using X-ray imaging for guidance, a catheter (a long, thin tube) is guided up the femoral artery in the groin to the blood vessel causing the nosebleed. Once in position, an embolizing agent in the form of either small resin particles (known as microparticles), small metal spirals (known as microcoils), a glue-like substance, or some other material, is injected to block the artery and stop the bleeding.

What are the benefits of this procedure?

  • Minimally invasive procedure that requires local anesthesia only
