An arteriovenous malformation (AVM) is an abnormal connection between arteries and veins that can be life-threatening if not treated in a timely manner. An AVM can cause serious medical issues including stroke, seizures, high blood pressure, and even death.
When an AVM is present, blood vessels in the area become dilated and can rupture, causing internal bleeding. This can lead to an aneurysm, which is a weakened area of the artery wall that can burst and cause severe bleeding. If the bleeding is not stopped in time, it can be fatal.
AVMs can also cause a stroke, as blood supply to the brain is interrupted due to the abnormal connection between the artery and vein. When the stroke occurs, it may cause permanent brain damage, paralysis, and even death.
Finally, AVMs can cause seizures, as the extra blood flow through the area causes the brain to become over-stimulated. Seizures can be dangerous, as they can cause loss of consciousness and can even cause death in some cases.
Overall, an AVM is definitely life-threatening and should be treated immediately. If left untreated, it can lead to serious medical issues such as stroke, seizures, high blood pressure, and even death. It is important to consult a doctor as soon as possible if you suspect you may have an AVM.
