Not all people have symptoms. Symptoms may vary in those who do. It depends on the size and location of the AVM. A person may have:
- Loss of movement on one side of the body
- Sudden, severe back pain
- Problems with certain movements, such as walking
- Speaking problems
- Vision problems
- Memory loss
- Confusion or problems thinking
- Shaking that they cannot control
The goal of treatment is to prevent bleeding and to remove the AVM.
Care depends on if the AVM has ruptured or not. Sometimes, more than 1 method is used. Care may be in a hospital.
Medicines may be given to manage an AVM that has not ruptured. They may also be given to ease:
- High blood pressure
- Blood clots
- Pressure inside the skull
If the AVM has ruptured, surgery may be delayed for 2 to 6 weeks. The type of surgery depends on the size and site of the AVM. Options are:
- Microsurgery—An operation to remove the AVM. A special microscope will help the surgeon see the area.
- Embolization—A tube is inserted through the skin. It is passed through arteries until it reaches the AVM. A substance is passed to the area. It will block off blood flow to the AVM.
- Radiosurgery—A beam of radiation is focused on the AVM. It destroys the blood vessel walls leading to the AVM. This will block off blood flow to AVM.
