CEREBRAL ARTERIOVENOUS MALFORMATION (AVM)
An arteriovenous malformation (AVM) in the brain is an abnormal connection of arteries and veins that disrupts the pattern of normal blood flow and pressure. It is present typically since birth and the exact cause is often unknown. AVMs may remain asymptomatic for many years or they can cause symptoms such as headaches, seizures, or neurological deficits, depending on their size and location. The severity of symptoms often increases if the AVM ruptures, leading to bleeding in the brain
The diagnosis of AVMs is confirmed through imaging studies such as cerebral angiography, CT scan,
or MRI.
Treatment options may include surgical removal through a craniotomy, embolization (blocking blood
flow to the AVM), or stereotactic radiosurgery to shrink or obliterate the malformation. This is achieved through a multidisciplinary team of neurosurgeons, interventional radiologists, and neurologists to determine the most appropriate treatment plan based on the specific characteristics of the AVM and the patient’ s overall health.
Causes
AVMs are often present at birth and result from abnormalities in the development of blood vessels in the brain.
Symptoms
Symptoms can include weakness, numbness, or paralysis in one part of the body.
Treatment
Some small AVMs may be observed without immediate intervention, especially if they are not causing symptoms.
Rehabilitation
Ongoing support for both the individual and their caregivers is crucial for the rehabilitation process.
Cerebral Arteriovenous Malformation (AVM)
Seizures
A common symptom is seizures, which may be the first sign of an AVM.
Speech and Language Difficulties
AVMs near language centers can lead to difficulties in speech and language.
Radiosurgery
Techniques like stereotactic radiosurgery use focused radiation to target and treat the AVM.
