What is Arteriovenous Malformation (AVM)?An arteriovenous malformation (AVM) occurs when the natural capillary system is bypassed by the network of arteries and veins and the blood gets transferred directly from the arteries to the veins without being supplied to the organs. It is most commonly seen in the central nervous system and can cause severe pain and bleeding along with other medical problems. This is mostly an asymptomatic condition which is often discovered in pursuit of diagnosis of another disorder. An AVM can occur almost anywhere on the body however the AVM in the brain is considered to be the most dangerous kind as even a small amount of bleeding from the arteriovenous malformation can cause neurological deficit, pain as well as epilepsy. The most common way an AVM is detected is when a person has epileptic seizures or constantly painful headaches. These are some of the other symptoms that are seen in a person suffering from AVM:
- Difficult hand-to-eye coordination
- Muscular weakness
- Dizziness (vertigo)
- Aphasia (communication difficulty)
- Dysarthria (speech difficulty)
- Apraxia (difficulty in normal activities)
- Spontaneous pain
- Tingling sensation
- Memory lapse
What are the surgical treatment options for an Arteriovenous Malformation (AVM)?There are various different methods to treat an AVM although most of these methods are concentrated mainly on preventing hemorrhage. The secondary aim of the AVM treatment method is to control seizures as well as any other possible neurological complication that may occur. The type of treatment is dependent on the patient’s health, age as well as the location and size of the abnormal blood vessels. The doctor usually prescribes medicines to treat symptoms of AVM such as seizures and headaches. Surgery is the main form of treating AVMs. These are the three different methods of surgical treatment of AVMS:
Resection (surgical removal)If the AVM is present in the brain in such an area that can be easily accessed by a conventional surgical method then the neurosurgeon will remove the part of the skull directly over the AVM affected part of the brain.

The surgeon then replaces the removed skull and closes the incision. The resection method is used only when the AVM can be easily reached and is not too deep inside the brain.
