Brain Arteriovenous Malformation (AVM)
Overview:A brain AVM (arteriovenous malformation) is a tangle of abnormal blood vessels in the brain that allows blood to bypass normal brain tissue and flow directly from arteries to veins. This can lead to a decreased supply of oxygen and nutrients to the brain, and can also increase the risk of bleeding in the brain (hemorrhage).
Symptoms
The symptoms of a brain AVM depend on its location and size, as well as whether or not it has ruptured. Some common symptoms of brain AVM include:
- Seizures
- Headaches
- Weakness or numbness in a limb
- Vision or speech problems
- Memory loss or confusion
Causes
The exact cause of brain AVMs is not known. It is thought that they may occur due to genetic mutations, but they can also occur spontaneously.
FAQ’s
How is a Brain AVM diagnosed?
A brain AVM is typically diagnosed through imaging tests, such as MRI, CT scan, or angiography.
How is a Brain AVM treated?
The treatment for a brain AVM depends on its size, location, and the patient’s overall health. It may be treated with surgical removal, embolization, or radiation therapy.
What is the recovery time after treatment for a Brain AVM?
The recovery time after treatment for a brain AVM varies depending on the extent of the AVM and the type of treatment. Some patients may recover fully within a few weeks, while others may require ongoing rehabilitation and monitoring.
Is a Brain AVM life-threatening?
Yes, a brain AVM can be life-threatening if it ruptures, causing bleeding in the brain. Close monitoring and early treatment are necessary to reduce the risk of complications from a brain AVM.
