The most common type of aneurysm is the saccular aneurysm, which is a saccular enlargement. “Pseudo Aneurysm” is a condition that occurs as a result of the weakening of the vascular wall for various reasons and expands without forming a sac. Another type, "mycotic aneurysm", is irregular ballooning that develops as a result of the weakening of the vascular wall due to microbial infection.

Aneurysms can also occur in other vessels in our body. The most distinctive feature that distinguishes aneurysms in the brain from other vessels is that the muscle layers of the brain vessels are thinner, that is, weaker, than other body vessels. This weakness makes it more likely that aneurysms will develop in the brain vessels. Aneurysms that develop in the brain, unlike other parts of the body, progress alone in the brain water, without any muscular support around them.

The most important aneurysm that develops in our body outside the brain is the aorta, which extends from the heart to the abdominal cavity. In any vessel, conditions that weaken the muscle due to injury to the wall may cause aneurysm formation. Brain and aortic aneurysms are the most dangerous.

During aneurysm treatment, it is essential to preserve the continuity of the vessel from which it originates. While brain aneurysms are closed with a device called "clip", aortic aneurysms are treated with stent application. In cases where the vessel diameter is large, stent application may be preferred.

In the last decade, there have been positive developments in coils, stents, which enable the aneurysm to be filled by entering the aneurysm intravenously, and methods that treat aneurysms by regulating blood flow. In addition, it is a great advance that operating microscopes that support microsurgical techniques offer ICG angiography during surgery.

If the main vein is preserved, it fulfills its duty as before and functions like a normal vein.
