Like most organs, the brain houses a complex network of veins and arteries that bring blood to its many sections and glands. A result of high blood pressure, head trauma or congenital defects, a cerebral aneurysm takes place when a wall of a vein or artery in the brain swells or bulges. A victim of a small aneurysm may display no symptoms, but a larger aneurysm will produce loss of feeling in the face and eye problems.
A cerebral aneurysm may rupture, depending upon its size and growth rate. When a cerebral aneurysm ruptures, the patient may experience severe headache, impaired vision, nausea and loss of consciousness. Generally, a ruptured cerebral aneurysm causes bleeding within the brain and can lead to blood clots within the skull and other problems. Surgery is required to combat a cerebral aneurysm, usually isolating the aneurysm to reduce the risk of it continuing to bleed over the brain.
“Coiling” of an aneurysm can block off the blood flow to the aneurysm and prevent it from rupturing. This is a neuroendovascular procedure in which the neurosurgeon place a small catheter in the femoral artery in the groin, advances the microcatheter into the brain, and through this catheter places coils in the aneurysm. The blood flow into the aneurysm is stopped and the aneurysm will not rupture.
