AVM stands for arteriovenous malformation, which is a rare vascular disorder caused by an abnormal connection between arteries and veins. It affects approximately 1 in 100,000 people and is more common in men than women. Symptoms can vary depending on the location of the AVM and may include headache, seizures, stroke, and bleeding. Treatment options include surgery, radiation therapy, and embolization.
The prevalence of AVM depends on the population being studied, but it is generally considered rare. In the United States, the incidence of AVM is estimated to be 0.1% to 0.2%, meaning that about 1 in 400 to 800 people are affected. The risk of having an AVM increases with age, and it is more common in men than women.
The causes of AVM are not completely understood. It is thought that genetic factors may play a role, as AVMs tend to run in families. Other risk factors include trauma, smoking, and chronic inflammation.
The diagnosis of AVM is made through imaging tests such as MRI or CT scans. Treatment options depend on the size and location of the AVM and may include surgery, radiation therapy, and embolization. Surgery is the most common treatment and involves the removal of the abnormal vessels. Radiation therapy and embolization can be used to reduce the size of the AVM or block off its blood supply.
In conclusion, AVM is a rare vascular disorder that affects approximately 1 in 100,000 people. The prevalence of AVM depends on the population being studied, but it is generally considered rare. Treatment options depend on the size and location of the AVM and may include surgery, radiation therapy, and embolization.
