A brain aneurysm does not make itself felt for a long time. Some people become aware of its existence during tests that diagnose other conditions, such as magnetic resonance imaging. Most often only when an aneurysm ruptures. This causes a sudden, very severe headache. There are other symptoms as well.
An aneurysm is a dangerous change in the structure of a blood vessel. As a result, there is a pathological expansion of the blood vessel, most often the artery (up to 50%). The walls of blood vessels become very thin and weak and can rupture, which poses a threat to the health and life of the patient. Aneurysms can form in different places and have different sizes, up to several centimeters. If the lesion occurs in the brain, it is called an intracranial or cerebrovascular aneurysm. According to statistics, this type of aneurysm affects 5% of the population. population of people around the world.
The causes of brain aneurysms are often difficult to diagnose. It may be caused by a birth defect. But it is known that untreated hypertension and atherosclerosis, weakening the vessel, contribute to the development of aneurysms. Among the factors contributing to the formation of a brain aneurysm are smoking, alcohol and drug abuse. Rupture of a brain aneurysm causes intense bleeding that is dangerous to health and life.
Symptoms of a brain aneurysm
Brain aneurysms are often asymptomatic. However, sometimes symptoms can occur when a growing aneurysm presses on one of the nerves in the brain. This is most often:
-
dilatation of one pupil,
-
double vision,
-
ptosis.
An aneurysm rupture is manifested by a very severe headache that occurs suddenly. It may be accompanied by:
-
neck muscle stiffness
-
photophobia,
-
nausea,
-
vomit,
-
speech disorders,
-
loss of consciousness.
Diagnostic test for brain aneurysm
Computed tomography of the brain can detect an aneurysm or confirm a hemorrhage, which is a consequence of its rupture. Another method for diagnosing an aneurysm is angiography of the brain. It consists in taking x-rays after the injection of a contrast agent into the intracranial arteries. Brain aneurysms are treated with surgery. Those that do not cause symptoms and have been found are treated routinely. When an aneurysm ruptures, immediate intervention is required. The success of the treatment largely depends on this.
