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 will use high-powered microscope to seal off the AVM with surgical clips and removes the surrounding brain tissue. 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.
This surgical procedure is performed using a catheter (thin surgical tube) which is inserted into one of the main arteries of the leg and is slowly pushed in, with the aid of x-ray imaging, till it reaches the brain.
This catheter is used to inject an embolizing agent (such as microcoils, adhesive substance or small particles) into the artery to block it and decrease the blood supply to it.
This is a minimally invasive procedure which is at times also used before other conventional procedures to decrease the risk of stroke by redirecting the blood to the brain tissue in a normal way.
Stereotactic radiosurgery (SRS)
This procedure uses focused beams of radiation to destroy the AVM and is a non-invasive technique for treating AVM.
This is the preferred method to treat smaller sized AVMs that are hard to remove with conventional surgery and also which are not at a risk of causing life-threatening hemorrhages.
Once removed there are no chances of the AVM of recurring as it is a congenital condition.
