Don’t be taken easy the seizures in children or adults.
Especially if accompanied by a severe headache that will not go away or suddenly
paralysis. It could be a symptom of vascular malformations of the brain
artery-vein.
Ordinary people refer to as epileptic seizures. Epilepsy
(epilepsy) could be due to electrical abnormalities in the brain cells, called
primary epilepsy, or a disorder in the brain, called secondary epilepsy.
Secondary trigger epileptic brain
abnormalities that may be abnormal formation of blood vessels connecting
arteries and veins in the brain (arteriovenous malformation) or because of
tumors.
Although abnormalities present at birth, many new symptoms
appear when the child is a teenager or adult.
Actually, this disorder can occur in any body part as long
as there arteries and veins. However, vascular malformations in the brain and
spinal cord have a more fatal.
Under normal conditions, the heart pumps oxygen-rich blood
and nutrients to the brain through arteries. Blood and entered capillaries.
Here, the blood flow is slowed to allow the release of oxygen to the
surrounding tissues. Furthermore, reduced oxygen content of blood delivered to
the heart through veins.
Without capillaries
Patients with arteriovenous malformation of the vein, blood
from an artery in the brain directly to veins without passing through
capillaries. Role of capillaries replaced abnormal blood vessels called a
fistula.
In fistula, blood flow becomes very fast. This is dangerous
because the release of oxygen to be more difficult. Rapid blood flow also makes
the pressure on the vessel wall becomes so high that can cause blood vessel
rupture and bleeding arise.
Rupture of blood vessels known as a stroke. Generally
induced hypertension stroke. However, bleeding in the brain can also be
triggered artery-vein malformation.
The bleeding can damage brain cells. The extent of damage
depends on the location of the arterial-venous malformation.
Mothers who suffer from vein arteriovenous malformation will
decrease 18 percent risk of malformations to her kids. However, the number of
cases of arteriovenous malformation vein revealed very little. Lack of public
awareness and the difficulty of the detection process makes a lot of people
with the malformation should receive no treatment.
Introduction vein
arteriovenous malformation symptoms needs to be done. However, those who have
symptoms of artery-venous malformations, such as seizures, bleeding in the
skull, or a headache will not go away even after treatment, no need to worry
immediately. Detailed examination required by a doctor to confirm the cause of
the symptoms.
Detection of malformations is often done using a magnetic
resonance imaging (MRI).
Therapy
To prevent to prevent stroke and improve patient quality of
life, there are at least three choices of action, microsurgery, endovascular embolization and
gamma knife radiation.
Micro-surgery suitable to remove the abnormal tissue
measuring more than 4 centimeters (cm) and were located at the surface of the
brain.
If abnormal tissue diameter less than 4 cm and its position
in the brain or between the brain hemispheres, the appointment should be made
with the gamma knife radiation. This technique is done by inserting radioactive
cobalt in the abnormal tissue.
Another treatment is endovascular embolization. This
technique is done by inserting embolan particles, similar to the glue, which
will freeze when entering the veins. Particle embolan inserted using a catheter
to a position near the abnormal tissue.
Endovascular embolization is not normally selected if the
network is widespread, reaching even half a brain. This therapy does not cure,
but it can reduce the risk. Blockage by embolan will reduce the risk of brain
hemorrhage.
The earlier-venous malformations of the brain arteries
detected, the higher the success rate of treatment. Hope for people to live a
normal life is wide open.
