What causes a basilar artery stroke?
2 A basilar artery stroke occurs when blood flow to the brain is interrupted. This can happen if the vessel becomes blocked (an ischemic stroke) or ruptured (hemorrhagic stroke). The basilar artery is located at the base of the brain, where the two vertebral arteries come together.
What is mid basilar occlusion?
Basilar artery occlusions (BAOs) are a subset of posterior circulation strokes. Particular issues relevant to BAOs include variable and stuttering symptoms at onset resulting in delays in diagnosis, high morbidity and mortality, and uncertain best management.
How is basilar artery occlusion treated?
For patients with atherosclerotic stenosis who survive basilar artery occlusion, the estimated annual risk of recurrent stroke is 20%. Antiplatelet agents such as aspirin, clopidogrel, and the combination aspirin/dipyridamole (Aggrenox) can be used for stroke prophylaxis.
What is basilar artery syndrome?
Top of the basilar syndrome, also known as rostral brainstem infarction, occurs when there is thromboembolic occlusion of the top of the basilar artery. This results in bilateral thalamic ischemia due to occlusion of perforator vessels.
What happens if the basilar artery is blocked?
Most commonly, patients experiencing basilar artery occlusion exhibit acute neurologic signs including motor deficits, hemiparesis or quadriparesis, and facial palsies, dizziness, headache, and speech abnormalities–especially dysarthria and difficulty articulating words.
What happens when the basilar artery is blocked?
What part of the brain does the basilar artery supply?
The basilar artery (BA) serves as the main conduit for blood flow through the posterior circulation. It directly supplies the brainstem and cerebellum and provides distal blood flow to the thalami and medial temporal and parietal lobes.
Can you recover from a basilar artery stroke?
Many patients without extensive ischemia on baseline imaging can recover well with aggressive modern stroke care. Basilar artery occlusion traditionally has been considered a catastrophe with a high rate of poor outcomes.
What does the basilar artery control?
Is there a prognosis for basilar artery thrombosis?
Basilar Artery Thrombosis. Acute basilar artery thrombosis is associated with a poor prognosis. However, the advent of high-quality, reliable, and noninvasive technology (eg, magnetic resonance imaging [MRI]) has made its diagnosis possible even in subjects with mild symptoms (see the image below).
How does basilar pneumonia affect the thoracic spine?
Basilar Pneumonia – Differential Diagnosis of the thoracic spine Basilar Pneumonia: Occurs as a result of the introduction and immunological response of a pathogen into the lungs, the body releases white blood cells to fight off this infection. This can cause fluid to fill up the alveoli and bronchi.
What causes the development of thrombosis in the basilar artery?
The reasons for the development of thrombosis of the basilar artery may be as follows: Congenital pathologies, such as an abnormal structure of the walls of blood vessels, a violation of the vascular tone. Also the process of thrombosis is promoted by such pathologies as Kimmerpi anomaly, various hypoplasia, dystonic changes;
What are the risk factors for a basilar artery stroke?
Similar to risk factors for stroke, causes of a basilar artery stroke include the following: Smoking. High blood pressure. Diabetes. Elevated cholesterol levels.
