What is Arteriovenous Malformation AVM

An Arteriovenous Malformation (AVM) is an abnormal tangle of blood vessels in the brain or spinal cord. It occurs when arteries and veins are connected directly, without the usual capillaries in between. This condition is considered rare and can develop anywhere in the body, but it is most commonly found in the brain.

AVMs can cause various symptoms depending on their size and location. Some individuals may experience no symptoms at all, while others may suffer from severe headaches, seizures, weakness, numbness, or even bleeding in the brain. The exact cause of AVMs is unknown, but they are believed to develop during fetal development or soon after birth.

Diagnosis of AVMs typically involves imaging tests such as angiography, MRI, or CT scans. Treatment options depend on the size, location, and symptoms of the AVM. In some cases, no treatment is necessary, but if the AVM poses a risk of bleeding or other complications, interventions like surgery, embolization, or radiation therapy may be recommended.

It is important for individuals with AVMs to receive regular medical follow-ups and to discuss their specific situation with healthcare professionals to determine the best course of action.
