Arteriovenous malformation (AVM) is a rare, abnormal tangle of blood vessels in the brain or spine that disrupts normal blood flow. This condition can lead to serious complications such as bleeding, seizures, and neurological deficits. AVMs are typically congenital, meaning they are present at birth, and their exact cause is not fully understood. Treatment options for AVMs may include surgery, embolization, or radiation therapy, depending on the size and location of the malformation. Research in this area focuses on understanding the underlying mechanisms of AVM formation, improving diagnostic techniques, and developing new and more effective treatment strategies for patients with AVMs.
