Treatment of brain aneurysms

Interventional treatment of brain aneurysms

Cerebral aneurysm is the expansion of brain vessels, resulting in the formation of a bubble in a part of the vessel.

Aneurysms in brain vessels are divided into several groups according to the reasons for their occurrence, location, and form: traumatic, narrow-necked, wide-necked, thin-walled, thrombosis, large, atherosclerotic aneurysm, etc.

Aneurysm causes

The structure of cerebral vessels is different from the structure of other vessels in the body. In some people, the folds in the blood vessels of the brain are opaque or weaker. Aneurysms are more common in this type of thin-walled vessels.

Brain aneurysms are most often caused by congenital vascular problems. Despite this, brain aneurysms are more common among patients aged 40-60 and sometimes even result in sudden brain hemorrhage.

When we talk about risk factors for brain aneurysms, of course, the genetic factor comes first. Other factors that cause aneurysms include: diabetes, high blood pressure, smoking and alcohol abuse, infections in the blood such as inflammation and sepsis, and blows to the head.

Unfortunately, brain aneurysms rarely present with any symptoms beforehand. One of these signs is severe headaches that start 2-3 weeks before the brain hemorrhage. However, these headaches are different from the previous ones and spread to the neck. In order to prevent brain bleeding, when you feel the symptoms of an aneurysm in the patient, you must consult a doctor. This can lead to the patient's earlier surgery, avoiding the risk of brain hemorrhage and even death.

Endovascular (coil embolization) treatment of brain aneurysms (vascular expansions) is many times less traumatic and less risky than surgical treatment. Even, the International Subarachnoid Aneurysm Trial (ISAT) in 1994 compared the endovascular (coil embolization) and surgical (clipping) treatment methods of ruptured cerebral aneurysms, preferred the endovascular (coil embolization) treatment method and recommended the surgical method only when endovascular treatment was not possible.
