Cerebral aneurysm is one of the causes of stroke, life-threatening because of its high mortality rate - considered a "silent killer". The treatment principle is to "remove the aneurysm by all means".

Microsurgical clamping of cerebral aneurysms is a surgery performed to treat aneurysms. When a brain aneurysm forms, it can become so thin that it is very fragile, causing bleeding to overflow into the brain parenchyma.

cerebral aneurysm is a bulge in an artery with a thin, weak wall. Under high blood pressure in the artery, they are at risk of rupture and causing intracranial hemorrhage, putting the patient in a critical condition or leaving serious sequelae later. Therefore, microsurgery to clip a cerebral aneurysm should be considered early to prevent complications and improve long-term outcomes.

The microsurgical procedure for clipping a cerebral aneurysm involves several steps that must be performed sequentially, with the ultimate goal being to actively control the aneurysm if it has not ruptured or to correct the brain hemorrhage if it has ruptured. Regardless of the clinical situation, a clear understanding of the following steps for cerebral aneurysm surgery will reinforce the correctness of this treatment decision.
