Arteriovenous Malformation (AVM) is not contagious. It is a rare condition that affects the blood vessels in the brain or spinal cord. AVM occurs when there is an abnormal tangle of blood vessels connecting arteries and veins, bypassing the capillary system. This can lead to various symptoms such as headaches, seizures, weakness, or even life-threatening hemorrhages.
AVM is a congenital condition, meaning it is present at birth and develops during fetal development. It is not caused by any infectious agent or transmitted from person to person. The exact cause of AVM is still unknown, but it is believed to be a result of abnormal development of blood vessels in the womb.
While AVM itself is not contagious, it is important to note that certain risk factors may increase the likelihood of developing an AVM. These include a family history of AVM, certain genetic disorders, and prior radiation therapy to the head or neck. However, these risk factors do not make AVM contagious either.
If you suspect you or someone you know may have an AVM, it is crucial to seek medical attention. Diagnosis typically involves imaging tests such as angiography, MRI, or CT scans. Treatment options vary depending on the size, location, and symptoms of the AVM, and may include medication, embolization, or surgical removal.
