Cerebral Aneurysm Causes, Treatment and Surgery
What is a Cerebral Aneurysm?
A cerebral aneurysm is the dilation, bulging, or ballooning out of part of the wall of a vein or artery in the brain. These can rupture and cause internal bleeding inside the brain and quickly becomes a life threatening issue. In most cases however, aneurysms do not rupture and in most cases do not even cause health problems or show symptoms. Cerebral aneurysms can occur at any age, although they are more common in adults than in children and are slightly more common in women than in men.
What are the Symptoms of a Cerebral Aneurysm?
Symptoms of cerebral aneurysms depend on the size of the aneurysm as well as how quickly it is growing. Small, unchanging aneurysms usually have no symptoms associated with them, while large quickly growing aneurysms may cause numbness in the face, a stiff neck, vomiting, drooping eyelids or vision problems. When an aneurysm ruptures, individuals usually show some or all of these symptoms: severe headache, nausea, vision impairment, vomiting, and loss of consciousness.
What Causes Cerebral Aneurysms?
Aneurysms develop due to a thinning in the artery walls, they are most common to appear at separations of different arteries because of the weakness in the vessel. They are most common near the base of the brain.
Is There Treatment for Cerebral Aneurysm?
In emergency situations, treatment involves reducing the intracranial pressure as much as possible and stopping the bleeding, this is usually done within the first 3 days. If an aneurysm is discovered before it ruptures, doctors may choose to perform surgery, or treat it with a craniotomy, microcoil thrombosis or a balloon embolization.
What is the prognosis?
The prognosis for a patient with a ruptured cerebral aneurysm depends on the extent and location of the aneurysm, the person's age, general health, and neurological condition.
