What is an AVM?
An Arteriovenous Malformation (AVM) is a rare, congenital disorder in which the walls of the affected arteries and veins do not form properly, resulting in a tangle of abnormal blood vessels that can be hazardous to one’s health. AVMs are often undetectable until they are discovered during a medical procedure or an imaging study such as an MRI or CT scan.
AVMs can occur anywhere in the body, however, they are most common in the brain and spine, leading to an increased risk of stroke and other serious medical conditions such as seizures and paralysis. In some cases, an AVM can be surgically removed, but in other cases, the malformation is too deep or too close to vital structures, leading to complications during surgery.
AVM is not a common disorder, and the exact prevalence is unknown. However, it is estimated that about 0.2-0.4 percent of the population has an AVM, with the majority of those affected being under the age of 25. The risk of AVM increases with age, and it is more common in males than females.
The causes of AVM are still not fully understood, however, some research suggests that it may be caused by a defect in the genes that control the development of blood vessels. It can also be caused by environmental factors such as radiation and certain medications.
AVMs can cause a variety of symptoms, depending on the size and location of the affected vessels. These can include headaches, seizures, difficulty speaking, paralysis, vision or hearing loss, and even death in some cases. If an AVM is suspected, a doctor will typically order an MRI or CT scan to confirm the diagnosis.
If the AVM is causing severe symptoms, treatment may be necessary. Depending on the size and location of the malformation, treatment may involve medications, surgery, radiation therapy, or a combination of these treatments. In some cases, the malformation may eventually heal on its own without any treatment.
In conclusion, AVM is a rare disorder that can cause a variety of symptoms. It is estimated that 0.2-0.4 percent of the population has an AVM, with the majority of those affected being under the age of 25. While the exact cause of AVM is still unknown, genetic and environmental factors may play a role. Treatment for AVM may involve medications, surgery, radiation therapy, or a combination of these treatments, depending on the severity of the condition.
