The result of rupture of the aneurysm is subarachnoid or intracerebral hemorrhage , which can lead to death or neurological disorders of varying severity associated with damage to brain tissue.
The most effective treatment is the early diagnosis and “turning off” of the aneurysm from the bloodstream through clipping or endovascular occlusion before rupture occurs.

Aneurysm structure
In the structure of the aneurysm allocate the neck, dome, body. The cervix has a three-layer structure of the vascular wall, therefore it is the strongest part of the aneurysm. The dome has only one layer of connective tissue , so the wall of the aneurysm is the thinnest and more prone to rupture. [one]
Classification
- In a form: saccular, spindle-shaped (fusiform).
- By value: billionths (diameter up to 3 mm), usual size (4-15 mm), large (16-25 mm), gigantic (more than 25 mm).
- By the number of cameras in the aneurysm: single-chamber, multi-chamber.
- Localization: on the anterior cerebral - anterior connecting arteries (45%), on the internal carotid artery (26%), on the middle cerebral artery (25%), on the arteries of the vertebro-basilar system (4%), multiple aneurysms - on two and more arteries (15%). [one]
