Disease of cerebral arteriovenous disease (AVM)


Arthrovenous deformation (AVM) is a group of blood vessels that do not interconnect unconditional among themselves. AVM can occur throughout the body, and AVM brains can be particularly harmful.Due to its structure, another term commonly used to describe AVM is’ Arteriovenous fistula.’

AVM consists of arteries and veins that are connected to each other Abnormally.

Matrix compounds to Vienna

There are two main types of blood vessels : arteries and Vienna. The arteries bring a rich blood of oxygen from the heart to each part of the body.When the artery is driving more deeply in tissues, they will destroy the inkotoinner of blood vessels until they become tiny and narrow.This area of small blood vessels is known as a capillary bed, where oxygen is delivered directly to each cell in the body.The capillary beds are combined to form veins, and they are gradually more when they go to organs on the way to the heart and light, where blood is replenished with oxygen.

Abnormal compounds of the artery to Vienna

The AVM brain consists of arteries And veins, who are connected in such a way that there is no capillary bed at all.This leads to the fact that the pressure of the arteries is transmitted directly to the veins within AVM.This blood flow creates a high pressure area and a high turbulence, which causes AVM to become more time and affects the role of surrounding brain tissue. .

How do you see?

Brain AVMs differ in size.Small white and may not cause any problem. Other form large and sinuous channels of arteries that are strongly pressed when they are directly connected to Viennes AVM.AVMS can be found at any point of the brain, including the bark of the brain, the white substance and the brain.

Who develops the AVMS brain?

The AVS brain affects more than 1% of the population, and is present at birth, but rarely affects more than one family member. They occur approximately equally in men and women.

Symptoms can start at any age, but people are often diagnosed after 50 years.


AVM can bleed or explosion, causing severe symptoms of subarachnoid hemorrhage . Half of ABM raises its first symptoms in this way.The symptoms of Broken AVM include a sudden and heavy headache, weakness of one side of the face or body, cramps, confusion, loss of consciousness or a constant head. / P>

Half of those who have symptoms of AVM experience, even if AVM does not bleed.They symptoms may include Convulsions , headaches and stroke symptoms, such as hemiplegia or hemiparesis.


The CT brain or MRI brain is necessary if your health care provider believes you may have AVM.

When bleeding was produced in the brain, AVM can be difficult to identify due to the presence of close blood.Other tests, such as cerebral angiography, brain mRA or the brain of the CTA, especially evaluate the strength of blood in the brain and can finally identify AVM.


The most common types of treatment types available include surgical removal, endovascular embolization and stereotactic radiation -All of which can be used alone, or in a combination. The number of these methods of treatment is to reduce the risk of bleeding or re-bleeding. / P>

The problem in which health care providers must be treated as a result of intensive research, Let them be discovered, before they cause bleeding.The risk of bleeding is weighted from the risk of operation for each person based on factors, such as general health and the ability to support the operation, location, size and AVM form.


The AVM prediction depends on several factors, starting with whether AVM is detected before or after bleeding. More than 90% of those who bleed, is experiencing an event.Those whose AVM is detected before bleeding, the forecast is directly related to the size of AVM, symptoms, proximity to vital brain areas, and if AVM is processed.

MEDS information word

You may have said that you or your favorite is AVMSI had a neurological deficit, such as weakness due to bleeding,You probably need to undergo any rehabilitation when restored. In general, with careful consequences and treatment, your prognosis is good.Regardless of whether your AVM Bled was or not, your treatment plan will include a narrow continuous your health team, since you and your health care providers determine whether surgical processing is the correct step for you.
