Aneurysms in the posterior circulation have a higher risk of rupture. A small, unchanging aneurysm will produce few, if any, symptoms. Symptoms include a sudden and unusually severe headache, nausea, vision impairment, vomiting, and loss of consciousness. About 60% of patients die immediately after rupture.
About Intracranial aneurysm in brief
Aneurysms in the posterior circulation have a higher risk of rupture. A small, unchanging aneurysm will produce few, if any, symptoms. Symptoms include a sudden and unusually severe headache, nausea, vision impairment, vomiting, and loss of consciousness. About 60% of patients die immediately after rupture. The risk of a subarachnoid hemorrhage is greater with a saccular aneurYSm. A ruptured microaneurysm may cause an intracerebral hemorrhage, presenting as a focal neurological deficit. Rebleeding, hydrocephalus, vasospasm, or multiple aneuryms may also occur. Cocaine use has been associated with the development of intracranialAneurysms. Genetic conditions associated with connective tissue disease and obesity may also be associated with brain aneurymes. Coarctation of the head and neck is also a known risk factor, as is arteriovenous malformation (AVM) – a malformation of the blood vessels that connect the brain to the rest of the body. Intracranial aneurism is a cerebrovascular disorder in which weakness in the wall of a cerebral artery or vein causes a localized dilation or ballooning of a blood vessel.
It is most likely to occur within 21 days and is seen radiologically within 60 per cent of such patients. It can be treated with surgery, but it can also be treated without surgery by a combination of drugs and/or surgery on the site of the aneuriesm, such as aorticectomy or an angioplasty. It may be difficult to treat with surgery as it is difficult to remove the aorta from the brain, and it can be dangerous to operate on the brain without a general anaesthetic. It takes up to three months for the brain’s blood vessels to recover from a stroke. The brain is the most vulnerable organ to a stroke, as it has a low blood pressure and a high blood pressure. It also has a high risk of bleeding from the nose and mouth. It’s possible to treat a stroke with surgery by cutting off the blood supply to the brain and using a defibrillator.
