What Is AVM Embolization?
AVM embolization is a minimally invasive endovascular procedure used to reduce blood flow through an abnormal connection between arteries and veins in the brain, known as an arteriovenous malformation (AVM). In selected patients, embolization may also be used as part of the treatment strategy for certain brain aneurysms and other complex cerebrovascular conditions.
During the procedure, an experienced neurointerventional specialist guides a thin catheter through the blood vessels to the targeted area. A specialized embolic material is then delivered to block or reduce abnormal blood flow. Depending on the patient's condition, embolization may be performed as a standalone treatment or before surgery or other procedures.
When Is AVM Embolization Recommended?
Your doctor may consider brain AVM embolization when an AVM or vascular abnormality has a significant risk of bleeding, is difficult to access surgically, or requires blood-flow reduction before another treatment. Detailed brain imaging and angiography are typically used to assess the location, size, blood-flow pattern, and overall treatment approach.
Recovery and Follow-Up
Recovery varies depending on the procedure and the patient's overall condition. Medical teams monitor neurological status and may recommend follow-up imaging to evaluate treatment progress. Your specialist will explain expected recovery, activity restrictions, warning signs, and further treatment if required.
