Treatment of Facial, Nose and Neck Bleeding:

Occasionally nosebleeds (epistaxis), bleeding from trauma or bleeding from a tumor cannot be controlled by conservative measures. Using angiographic techniques,It is possible to inject arteries with a substance that closes the leaking vessel, thus halting bleeding. This process, called embolization, is performed in the neurointerventional suite while a patient is under sedation. First, a diagnostic angiogram of the problematic area is performed. Once the site of bleeding is identified, a microcatheter is advanced to the area of bleeding and particles are injected to permanently close the artery. 

After embolization, most patients are observed in hospital overnight to determine the procedure was fully successful.
