"At what size does a brain aneurysm become prone to rupture?"

Cerebral Aneurysm

A cerebral aneurysm is a localized, abnormal enlargement within the lumen of a cerebral artery, resulting in a tumor-like protrusion of the arterial wall with a diameter exceeding 5mm, predisposing it to rupture. Aneurysms are considered as ticking time bombs in the human brain, with the primary risk being rupture and subsequent bleeding. Generally, the larger the aneurysm, the higher the likelihood of rupture, particularly for those exceeding 5mm in diameter.

Aneurysms with diameters not exceeding 5mm are classified as small. Typically, the larger the aneurysm, the more prone it is to rupture, and those over 5mm pose a significant risk of rupture. In the event of rupture, the hemorrhage can be substantial and may form eddies, leading to ischemic stroke. Ruptured cerebral aneurysms cause cerebral hemorrhage, which can be life-threatening in severe cases. Patients who have been diagnosed with cerebral aneurysms should undergo timely treatment to prevent rupture.

For unruptured intracranial aneurysms, the treatment principle is to prevent rupture and bleeding. Two common approaches are craniotomy with clipping and endovascular embolization. Craniotomy with clipping involves tying off the base of the intracranial aneurysm, depriving it of blood supply and thereby eliminating the risk of rupture. Embolization, on the other hand, involves placing coils within the aneurysm to reduce blood flow impact on the vessel wall, thereby lowering the risk of rupture.

In daily life, maintaining a calm mindset, avoiding strenuous exercise, and controlling blood pressure, blood sugar, and lipid levels are crucial. A light, healthy diet should be prioritized. Regular follow-up examinations, proper life care, balanced diets, and moderate exercise are also important, along with adhering to medical advice and treatment plans.
