Brain Arteriovenous Malformation (AVM) Treatment in Bangalore
Expert AVM surgery, embolisation, and Gamma Knife at Bangalore's top neurovascular centres.
A brain arteriovenous malformation (AVM) is an abnormal tangle of blood vessels connecting arteries and veins, bypassing the normal capillary system. AVMs can rupture and cause brain haemorrhage, or cause seizures, headaches, and neurological deficits. Treatment requires a multidisciplinary approach combining microsurgery, endovascular embolisation, and stereotactic radiosurgery. Bangalore's neurovascular centres have experienced teams for all three modalities.

Symptoms of Brain AVM
Sudden, severe headache from AVM rupture (haemorrhage)
Seizures (fits) — often the first symptom of unruptured AVMs
Progressive neurological deficits: weakness, numbness, vision problems
Pulsatile tinnitus (whooshing sound in the ear)
Headaches
Many AVMs are discovered incidentally on brain imaging
Causes & Risk Factors
Congenital — most AVMs are present from birth
Genetic factors — hereditary haemorrhagic telangiectasia (HHT)
Rare acquired AVMs after brain injury or infection
Treatment Options
Brain AVM Treatment in Bangalore
Bangalore's top neurosurgery hospitals offer the full spectrum of treatment options for Brain AVM.
Microsurgical Resection
Open surgery to remove the AVM. Most effective for small, superficial AVMs (Spetzler-Martin Grade 1–2). Immediate cure if complete removal achieved.
Endovascular Embolisation
Catheter-based injection of glue or coils to reduce blood flow through the AVM. Usually combined with surgery or radiosurgery rather than used alone.
Gamma Knife / Stereotactic Radiosurgery
For small, deep AVMs not suitable for surgery. Radiation causes gradual obliteration over 2–3 years. 80–90% obliteration rate for AVMs under 3 cm.
Observation
For unruptured AVMs in elderly patients or high-risk locations, the risks of treatment may outweigh the benefits. Regular MRI monitoring.
