Brain AVM Embolization with Onyx Cost in India

The cost of brain AVM embolisation (Onyx) in India typically ranges from $6,000 to $12,000 USD, depending on the hospital, city, and type of procedure.

Brain AVM embolisation blocks an arteriovenous malformation from inside the blood vessels. It uses a liquid embolic agent such as Onyx, delivered through a catheter. The cost depends on:

• Number of sessions: large AVMs may need several.
• Amount of embolic agent and devices
• Combined treatment: with surgery or radiosurgery.
• Intensive care

An AVM may be treated with embolisation, surgical removal, stereotactic radiosurgery, or a combination. Some unruptured AVMs are monitored without treatment. The best choice depends on size, location and whether it has bled, decided by a neurovascular team.

Cambridge University Hospitals explains that high-flow lesions are treated through an artery or vein in the groin. It notes that more than one procedure is sometimes needed. Embolisation may cure small AVMs or make surgery or radiosurgery safer.

The CUH leaflet lists incomplete treatment as the main risk, plus bleeding, infection and radiation exposure. In the brain, embolisation also carries a risk of stroke. Ask about your individual risk.
