All About
Brain AVM Embolization with Onyx
Symptoms
- Severe headache.
- Weakness, numbness or paralysis.
- Vision loss.
- Difficulty speaking.
- Confusion or inability to understand others.
- Severe unsteadiness.
Causes
The cause of cerebral AVM is unknown. An AVM occurs when arteries in the brain connect directly to nearby veins without having the normal small vessels (capillaries) between them. AVMs vary in size and location in the brain. An AVM rupture occurs because of pressure and damage to the blood vessel.
More about Treatment
The treatment of brain arteriovenous malformations (AVMs) is challenging based on a multidisciplinary approach involving neurosurgery, radiosurgery, and interventional neuroradiology. The embolization of brain AVMS was for a long time performed using particles and glue. Onyx has been recently introduced in the armamentarium for AVM embolization, but large, multicenter evaluation is lacking. BRAVO study was conducted to evaluate the clinical and anatomical results of brain AVM embolization with Onyx.
FAQ on this Treatment
Is brain AVM embolization with Onyx a dangerous procedure?
It is an overall safe and standardized procedure adopted very frequently for AV malformation correction.
What are the side effects of brain AVM embolization?
Brain AVM embolization rarely shows side effects like weakness in limbs, numbness, stroke-like symptoms, speech disturbance etc.
What is the recovery period of brain AVM embolization surgery?
Full recovery takes few months, but normal day to day activities can be resumed after 4 to 6 weeks. If side effects are seen, rehabilitation programmes may also be advised during this period.
