Prior to Embolization of Arteriovenous Malformation and Fistula in Brain radiology procedure:
How does the Embolization of Arteriovenous Malformation and Fistula in Brain radiology procedure work?
- A catheter is inserted into the artery using an imaging technique and sent to the site of the arteriovenous malformation (AVM)
- The catheter is placed at the abnormal connection between the artery and vein, as a liquid adhesive agent is injected. The liquid adhesive agent blocks the abnormal connection between the artery and vein
How is the Embolization of Arteriovenous Malformation and Fistula in Brain radiology procedure Performed?
The Embolization of Arteriovenous Malformation and Fistula in Brain procedure is performed in the following manner:
- A CT scan or MRI is performed before the embolization procedure
- The patient’s heart rate, blood pressure, and pulse are monitored
- An intravenous (IV) line is inserted into the patient’s arm and sedatives are given through IV lines
- A catheter is inserted and sent to the site of the arteriovenous malformation
- Liquid agents are then used to plug the abnormal connection
- The catheter and IV lines are removed at the end of the procedure
- If the AVM was leaking, then the patient is hospitalized for a few days
Where is the Procedure Performed?
An Embolization of Arteriovenous Malformation and Fistula in Brain procedure is performed as an outpatient procedure, at a hospital.
