Aneurysm of the brain is a disease, with a violation of the structure of spinal cord or brain, which indicated the formation of saccular enlargement of the vascular walls. The most common cause of this pathological condition can include trauma, congenital changes in the structure of vascular walls, as well as atherosclerosis. Brain aneurysm symptoms are directly dependent on the location of saccular expansion, as well as the existing complications. Identify this pathology can be through nuclear magnetic resonance or computed tomography. It is these diagnostic methods make it possible to establish the exact location and size of the aneurysm. Treatment of this disease is carried out by surgical intervention.

What is an aneurysm of the brain, and what are the reasons for its development?

Cerebral aneurysms - a sac-like or rounded extension of arterial walls of the spinal or brain. The most frequent causes conducive to the development of this disease is considered to be vascular abnormalities or disorders of the structure of vascular walls, which are observed in a child with the first day of his birth, then there are innate. There are cases when the development of this disease was caused by atherosclerosis of cerebral vessels. Much less likely this disease is a consequence of injury.

Aneurysm - what can they be?

Depending on the location of the expansion in the nervous system, experts distinguish two kinds of pathological condition - it aneurysms of spinal cord and the extension of cerebral vessels. If we talk about extensions of cerebral vessels, they occur in medical practice more often. They may be located both in the brain, and at the base of the skull, namely in the area of circle. This pathology has another classification, which is characterized by the nature of its flow. In this case, it can be arterial or arteriovenous.

Arteriovenous aneurysm - all in their appearance resembles a tangle consisting of extended venous vessels of the brain. There is this kind of disease due to a direct relationship between venous and arterial vessels of the brain. Well-known fact is that the pressure in the arteries is much higher than the level of blood pressure in the veins. It turns out that the direct relationship between the veins and blood vessels; arterial blood with incredible force goes straight into a vein. As a result, the veins dilate, which promotes the development of aneurysms. Manifestations of this form of the disease resemble a number of symptoms that characterize the states of compression of brain tissue, as well as insufficient blood supply to the brain. The most common signs of this pathology could be considered: epileptic seizures, migraine headaches, disturbances of movement and sensitivity. In spite of this about fifty percent of the expansion occurs without any symptoms. Rupture of arteriovenous expansion occurs as a result of excessive thinning of the walls, as well as increased blood pressure inside it. As soon as there is a rupture, a person begins immediately intracranial bleeding, which can be fatal. Define the beginning of intracranial bleeding can be on the following grounds: violation of consciousness up to coma, sudden loss of movement or sensitivity, a very bad headache.
