Why do intracranial aneurysms occur? What are the causes?

Aneurysms have a great impact on the patient's physical health. If an aneurysm is found in the head, many patients will feel worried and distressed. Next, the author will introduce to you why aneurysms grow in the brain? What are the causes?

Intracranial aneurysm refers to a tumor protruding from the arterial wall caused by localized abnormal expansion of the lumen of a cerebral artery. Intracranial aneurysm is mainly a cyst caused by local congenital defects of the cerebral artery wall and increased cavity pressure, and is the first cause of subarachnoid hemorrhage.

Once an aneurysm ruptures and bleeds, the clinical manifestation is severe subarachnoid hemorrhage, which occurs rapidly and causes severe headaches, which the patient describes as "head exploding". Frequent vomiting, sweating, and fever; the neck is straight and the Klinefelter sign is positive. There may also be impaired consciousness or even coma. Some patients have causes such as fatigue and emotional excitement before bleeding, while some patients have no obvious causes or diseases during sleep.

The cause of aneurysm is not very clear, and the causes of aneurysm are summarized as follows: ① congenital factors; ② arteriosclerosis; ③ infection; ④ trauma. Rare causes such as tumors can also cause aneurysms, abnormal vascular network diseases at the base of the skull, cerebral arteriovenous malformations, abnormal intracranial vascular development, and cerebral artery occlusion.

The treatment of aneurysms in different parts is different. The main treatment methods are surgical treatment, endovascular repair of aneurysms and aneurysm embolization. The principle of surgery is aneurysm resection and arterial reconstruction. Reconstruction methods include arterial rupture repair, arterial patch inhibition and arterial end-to-end anastomosis. Endovascular repair uses a coated artificial vascular stent for endovascular repair of aneurysms. It is less invasive and has a definite effect, but the indications must be strictly controlled. For some visceral aneurysms, coil embolization can be used to form thrombosis to prevent further expansion of the tumor, rupture and bleeding.

The causes of intracranial long aneurysms can be referred to the above introduction, and timely treatment should be received under the guidance of a pharmacist to help with early recovery.
