Aneurysm Clipping

What is an aneurysm?

An aneurysm develops due to an abnormal bulge in the blood vessel wall. This can occur without any symptoms, but when an aneurysm ruptures, it can result in serious complications such as excessive bleeding. Symptoms of a ruptured aneurysm include a sudden, severe headache, nausea, vomiting, and sensitivity to light.

An aneurysm may form in any of the blood vessels of the brain, which is referred to as a cerebral aneurysm. While clipping is a viable treatment option for a brain aneurysm, endovascular coiling may also be done. Coiling entails the insertion of a catheter into the arteries, which is usually through the groin, and the tiny platinum coils are left inside the aneurysm dome to enable it to clot and minimise further blood flow to the aneurysm. This is because blood cannot penetrate the region if the aneurysm is filled with coils. This is a desirable surgical option as there’s no need to create any incisions in the head. Unfortunately this service can’t be offered by Dr Naicker but he will be able to evaluate, counsel and come up with an appropriate treatment plan and referral.

What is aneurysm clipping?

An aneurysm clipping is done via a craniotomy, which involves inserting a tiny metal clip at the base of the aneurysm to minimise the risk of blood leaking into it. This procedure, like any surgery, carries certain risks, such as infection, bleeding, stroke or adverse reactions to anaesthesia. However, it also offers significant benefits, safeguarding the patient and minimising the risk of rupture and death.

How do you clip an aneurysm?

Aneurysm clipping is a microsurgical procedure that demands the utmost precision. It involves inserting a metal clip over the brain aneurysm neck to prevent it from bursting. This is done under the surgical microscope which aids in illumination and magnification. This precision is crucial, as it's paramount to preserve the surrounding structures, such as the blood vessels, nerves, and brain tissue, ensuring the patient's safety and recovery.

During aneurysm clipping, an opening is made in the skull, after which the blood vessels and aneurysm are carefully separated from the brain tissue. Next, the clip is strategically yet gently placed over the neck of the aneurysm, the bone is carefully replaced, and finally, the incision is sealed. This highly effective procedure ensures the aneurysm is cut off from its blood supply, reducing the risk of rupture and death.
