A Weston, Florida, neurosurgeon with more than 15 years of professional experience, Dr. Badih Adada cares for patients at the Cleveland Clinic. Dr. Badih Adada is experienced in surgical approaches to diverse conditions, from benign brain tumors to vascular malformations.

Arteries provide oxygen-rich blood to the normally functioning brain, with veins returning blood containing less oxygen back to the heart. One of the conditions associated with strokes, arteriovenous malformation (AVM), involves a tangle of blood vessels that bypass the normal brain tissue to which blood is supplied. Instead, the blood is diverted directly from the arteries to the veins that return blood to the heart.

A relatively rare condition, AVM involves weakened blood vessels that can gradually dilate. The high pressure from the arteries’ blood flow may ultimately result in their bursting, causing dangerous bleeding. More than half of AVM patients experience intracranial hemorrhage, which is best treated through surgical removal of the affected area. When the AVM is completely removed, chances of further bleeding are extremely low.
