If you ask, “How to prevent brain aneurysms” we have prepared the answer for you. What are brain aneurysms? how to prevent What are the treatment methods? we will examine.
Aneurysms are protrusions and bubbles in the arteries and aortic vessels in the body. A brain aneurysm is the bulge or ballooning of blood vessels in the brain. Brain aneurysms are caused by thinning of the arterial wall.
When viewed on brain MRI or tomography, these protrusions or bubbles usually give the image of hanging fruit on the branch. One out of every 10 people with a brain aneurysm develops a cerebral hemorrhage as a result of the bursting of the bubble. Severe headache, double vision, and droopy eyelid are symptoms of brain hemorrhage.
While brain aneurysms can be alarming, many brain aneurysms do not cause symptoms or cause health problems. However, if there is a family history of aneurysm, it is very important to undergo regular health check-ups and to take care for future problems.
Although the cause of aneurysms is not known exactly, it is estimated that smoking, high blood pressure, and familial factors play a role.
Many factors can lead to the development of aneurysm by weakening the artery wall. Brain aneurysms are common in adults. In addition, it is more common in women than in men.
- Advanced age (after the age of 40)
- Smoking: Cigarette may cause earlier development of the already existing problem and bleeding by aging the vascular structure.
- Atherosclerosis (hardening of the arteries)
- Drug use (especially cocaine)
- Damage to the vessels after head traumas and other traumas
- Cancer or the presence of a tumor in the head or neck
- Some blood infections
Congenital Risk Factors
- Connective tissue diseases (such as Ehler-Danlos disease)
- Polycystic kidney disease
- Rheumatic diseases
- Marfan Syndrome
- Aortic coarctation
- Arteriovenous malformation (cerebral vascular ball) in the brain
- Having had a previous brain aneurysm in the family.
Brain aneurysms can show symptoms in two ways. The first of these occurs as a result of compressing any area in the brain tissue due to the mass effect. In such cases, the function of the compressed area cannot be fully fulfilled and related problems occur. For example, aneurysm can occur next to an important nerve that moves the eyelid.
As a result of the pressure of the aneurysm on this nerve, the patient may develop droopy eyelid or enlarged pupil. For this reason, the drooping of the eyelid should be taken into consideration as it may be a sign of aneurysm.
If the non-ruptured aneurysm is small, it may show no symptoms. However, large non-ruptured aneurysms can put pressure on brain tissue and nerves, giving some symptoms:
- Pain behind the eyes
- Wide pupil
- Visual field disorders, double vision
- Numbness, weakness, paralysis on one side of the face (facial paralysis)
- Drop in the eyelid
The second is the bleeding findings, which are more severe than the first, that occur when the aneurysm bursts.
Severe headache is the first sign of a bleeding brain aneurysm. The patients stated that the headache developed in a severity that they had not experienced before and said, “Something exploded in my head”.
There is a water layer under the membrane layer around the brain. Bleeding also flows into this water and spreads wherever the water of the brain flows. As a result of the impaired circulation of the brain water, the pressure in the head increases. That’s why headaches occur in brain aneurysm. In addition to the pain, the following symptoms may also occur:
- Nausea, vomiting
- Double and blurred vision
- Confusion: Impaired memory, perception, and attention
- Light sensitivity
- Loss of consciousness
How to prevent brain aneurysms
Today, there are two effective treatment methods for aneurysms that cause bleeding by tearing:
Brain surgery is performed and the aneurysm balloon is closed with clamps called Clip. During surgery, your doctor reaches the aneurysm by removing a portion of the skull bone and opening the meninges and finds the main vein that feeds the aneurysm. It places a metal clip where the aneurysm is opening to interrupt the blood flow and stops the blood flow.
It is not an operation in which the skull is opened. A soft platinum wire is inserted into the vein, usually with the help of a catheter placed in the groin. The wire is placed in the ball-shaped balloon, forming a clot and stopping the blood flow.
Both processes have risks. Although endovascular treatment seems safer and non-invasive, the risk of recurrent bleeding is higher and may require additional procedures.
Surgery that Changes the Direction of Flow (Attaching a Mesh)
It is used for larger aneurysms where surgery or endoscopic method may not work. It is performed with open surgery under general anesthesia and the skull and membrane are opened. In this procedure, your doctor places a stent in the inner wall of the artery in the brain that changes the direction of blood flow. Thus, blood accumulation and bursting of the vein are prevented.
If you are having problems with your health, you should go to the doctor or call 911. If you want to know more about these, you should follow U.S. Department of Health & Human Services.
