How do I know if I have Arteriovenous Malformation AVM?

Arteriovenous Malformation (AVM) is a rare condition characterized by abnormal connections between arteries and veins in the brain or spinal cord. It is important to be aware of the signs and symptoms associated with AVM, as early detection and treatment can be crucial in preventing serious complications.

1. Family history: AVM can sometimes be hereditary, so if you have a close family member who has been diagnosed with AVM, it increases your risk of having it as well. It is important to inform your healthcare provider about any family history of AVM.

2. Neurological symptoms: AVMs can cause a variety of neurological symptoms, which may vary depending on the location and size of the malformation. Common symptoms include:

• Severe headaches or migraines


• Seizures or convulsions


• Weakness or numbness in the limbs


• Difficulty speaking or understanding speech


• Problems with vision, such as blurred or double vision


• Dizziness or loss of balance


• Memory or cognitive problems

3. Bleeding: AVMs have a risk of bleeding, which can lead to a sudden and severe headache, nausea, vomiting, and even loss of consciousness. If you experience any of these symptoms, it is crucial to seek immediate medical attention.

4. Other associated conditions: AVMs can sometimes be associated with other conditions, such as aneurysms or cavernous malformations. If you have been diagnosed with any of these conditions, it is important to discuss the possibility of AVM with your healthcare provider.

5. Diagnostic tests: If you suspect you may have AVM or if you experience any of the aforementioned symptoms, your healthcare provider may recommend further diagnostic tests. These may include:

• Magnetic Resonance Imaging (MRI): This imaging technique can provide detailed images of the brain or spinal cord, helping to identify the presence of AVM.


• Computed Tomography (CT) scan: This imaging test can help detect bleeding or abnormalities in the brain.


• Cerebral Angiography: This invasive procedure involves injecting a contrast dye into the blood vessels to visualize the blood flow and identify any abnormal connections.

If you suspect you may have AVM or if you experience any concerning symptoms, it is important to consult with a healthcare professional. They will be able to evaluate your symptoms, assess your risk factors, and recommend appropriate diagnostic tests if necessary. Remember, early detection and treatment can significantly improve outcomes for individuals with AVM.
