A cerebral aneurysm is a bulging in the wall of a blood vessel supplying the brain. the sequel is more serious stroke. symptoms.

An aneurysm in the brain occurs when the wall of a blood vessel is weakened. May be congenital or may develop through life. The most common type of aneurysm is the berry aneurysm and can vary in size from a few millimeters to over a centimeter, can reach up to two centimeters. It is sometimes inherited from parents to children more frequently than other less common aneurysms

Diseases that can cause an aneurysm

Other types of cerebral aneurysm involve widening of an entire blood vessel or may appear as a “bulge” of part of a blood vessel. These types of aneurysms can occur in any of the blood vessels supplying the brain.

· Atherosclerosis .
· Trauma.
· Infection. can injure the vessel wall and can cause brain aneurysms.
· Polycystic kidney disease.
· Coarctation of the aorta.
· Endocarditis.
· Hypertension ·

Symptoms of brain aneurysm

A person may have an aneurysm without having any symptoms. This type of aneurysm may be found when an MRI. A cerebral aneurysm may begin to “leak” a small amount of blood, which can cause a very strong headache. Therefore a headache may be a symptom or warning sign of a break, days or weeks after the headache occurs for the first time. Symptoms may also occur if the aneurysm presses on nearby structures in the brain or opens (breaks) and cause interracial bleeding. Symptoms depend on the location of the aneurysm, if it breaks or not and on what part of the brain is pressing, these include:

aneurysm-symptom

· Double vision.
· Loss of vision.
· Headaches.
· Pain in the eye.
· Pain in the neck.
· Stiff neck.
· Confusion, drowsiness.
· Eyelid drooping.
· Headaches with nausea or vomiting.
· Difficulty moving any body part.

Numbness or decreased sensation in any.

· Speech.
· Stiff neck (occasionally).
· Changes in vision (double vision or loss of it)

Treatment of cerebral aneurysm

Two methods are used to cure common aneurysm.

· The clipping is done during open surgery, neurosurgery.
· Endovascular repair is almost always implies the use of a “spiral” or embolization . It is a less invasive way to treat some aneurysms. And faster recovery.

Even when there are no symptoms, the doctor may order treatment to prevent future possibly fatal rupture.Not all aneurysms need immediate treatment. Those are very small (less than 3 mm) are less likely to break. In some cases it is possible to treat the aneurysm, for two reasons: One who is in a difficult location brain. Second the person is too ill to stand this intervention. This treatment of a ruptured aneurysm may involve:

· Be committed to an intensive care unit (ICU).
· Bed rest and activity restrictions.
· Drainage of blood from the area of ​​the brain (cerebral ventricular drainage)
· Drugs to prevent seizures or convulsions
· Medications to control blood pressure and headaches.
· Intravenous to prevent infection.

Once an aneurysm has been repaired, it may be necessary prevention of stroke due to spasm of blood vessels.

Consequences of cerebral aneurysm

It is estimated that the bleeding caused by a brain aneurysm kills about 60% of its victims,incapacitates the 20 to 30% and just over 10% of patients able to maintain a normal rhythm of life after a stroke (ACV).
