An aneurysm is a balloon that forms in blood vessels as a result of weakening of the walls of the blood vessels. It refers to the balloon-like enlargement that occurs in the main arteries feeding the brain. The vessel wall where the aneurysm develops is thinner than the normal vessel wall and bursts where it is thin, causing cerebral hemorrhage.
In an aneurysm, there is a risk of weakness, thinning and rupture of the vessel wall. The biggest cause of aneurysm formation is arteriosclerosis. According to researches, aneurysm is seen in women and generally in people over the age of 30-40. There is also a genetic predisposition to aneurysm formation. There are factors that increase the likelihood of an aneurysm rupturing and bleeding. These factors include high blood pressure, smoking or sudden high blood pressure due to stress.
What are the Symptoms of Aneurysm?
An aneurysm is caused by the weakening or underdevelopment of the intravascular muscle layer in the vessel walls, which forms the entire vessel, due to some congenital or acquired causes. Some factors trigger an aneurysm and there is a risk of rupture as the vessel wall becomes thinner and weaker. We can list the symptoms of aneurysm as follows;
- Double and blurred vision
- Other vision loss in the eyes
- Excessive, persistent and severe headache
- Eyelid drooping
- Nausea and vomiting
- Sudden contractions in physical movements
- Some of the symptoms listed can also be considered as symptoms of other diseases.
How is aneurysm treatment performed?
Balloons that form in the vessels are called "aneurysms". Aneurysm rupture, i.e. aneurysm rupture, can be seen at any age. It is possible to detect them beforehand. A cerebral angiography through the groin can detect aneurysms that have formed in the vessels of the brain and have not yet burst. Just as with heart angiography, there are some risks involved in brain angiography. There is a risk of aneurysms in the brain vessels bursting during angiography.
It is possible to treat aneurysms detected without bursting. Endovascular coiling (platinum coil placed inside the bubble) is used in the treatment.
A plastic tube is inserted through the patient's groin and is guided along the vessel until it reaches the aneurysm. When the center of the bubble is reached, the platinum hair is twisted through the tube into the bubble and the spiral in question is enlarged until a spiral ball is formed.
When the ball-shaped platinum spiral completely covers the bubble, its connection with the hair (micron-sized wire) inside the tube is broken by a process called electrolytic separation. The main purpose here is to fill the inside of the bubble and allow the blood flowing in the vein to bypass the bubble by cutting its contact with it.
The reason why the spiral is made with platinum wire is to ensure that the spiral can be monitored by the simultaneous x-ray device used during the operation, which makes this type of operation possible. The name given to this technology is Detachable Platinum Coil Technology.
