Basilar artery aneurysm refers to a condition characterized by the abnormal bulging or swelling of a blood vessel known as the basilar artery that supplies oxygenated blood to the brainstem and cerebellum. An aneurysm is a weakened area that develops in the wall of a blood vessel, causing it to balloon outwards and potentially rupture.
The basilar artery is one of the major arteries in the brain, responsible for supplying crucial blood flow to vital brain structures. When an aneurysm forms in the basilar artery, it can disrupt the normal blood flow, potentially leading to serious health consequences. Basilar artery aneurysms are relatively rare compared to aneurysms occurring in other cerebral arteries.
The causes of basilar artery aneurysms are often related to underlying vascular conditions, such as atherosclerosis (build-up of fatty deposits), high blood pressure, or genetic factors. Additionally, certain risk factors may increase the likelihood of developing this condition, including smoking, excessive alcohol consumption, and a family history of aneurysms.
The symptoms of a basilar artery aneurysm can vary depending on its size, location, and whether it has ruptured. Common signs include severe headaches, double vision, difficulty swallowing or speaking, loss of coordination, dizziness, and changes in consciousness. A ruptured basilar artery aneurysm is a medical emergency and may result in a subarachnoid hemorrhage, causing severe and sudden headache, loss of consciousness, stiff neck, and sometimes coma or death if not promptly treated.
Treatment options for basilar artery aneurysms depend on various factors, such as the size and location of the aneurysm and the patient's overall health. They may include surgical interventions like clipping
