What is a basilar stroke?
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..
What is the longest vein in the body?
Great Saphenous VeinDid you know that your Great Saphenous Vein is the longest vein in the human body? Extending from the top of your foot to the upper thigh and groin, THIS vein is the major culprit that causes Varicose Veins.
What is the main artery that carries blood from your legs to your heart?
The superior vena cava is the large vein that brings blood from the head and arms to the heart, and the inferior vena cava brings blood from the abdomen and legs into the heart.
Which artery is most important for speech and language functioning?
The middle cerebral artery (MCA) is a critical artery which has an extensive clinical significance.
What makes up the basilar artery?
The basilar artery is a midline structure formed from the confluence of the vertebral arteries. Terminally, the basilar artery branches to establish the right and left posterior cerebral arteries.
What artery supplies blood to the brainstem?
Major Blood Vessels The external carotid arteries supply the face and scalp with blood. The internal carotid arteries supply blood to most of the anterior portion of the cerebrum. The vertebrobasilar arteries supply the posterior two-fifths of the cerebrum, part of the cerebellum, and the brain stem.
Where does the blood go after it leaves the basilar artery?
It provides blood to the posterior portion of the cerebrum and brain stem. The basilar artery is an anastomosis that begins at the junction of the two vertebral arteries and sends branches to the cerebellum and brain stem. It flows into the posterior cerebral arteries.
What is lock syndrome?
Locked-in syndrome is a rare neurological disorder in which there is complete paralysis of all voluntary muscles except for the ones that control the movements of the eyes.
Which is the largest artery in our body?
aortaThe largest artery is the aorta, the main high-pressure pipeline connected to the heart’s left ventricle. The aorta branches into a network of smaller arteries that extend throughout the body. The arteries’ smaller branches are called arterioles and capillaries.
How do you tear a basilar artery?
These findings indicate that when the man fell into the ditch, severe hyperextension occurred as a result of minor blunt forces to the face, and that the traumatic tear of the basilar artery was mechanically caused by overstretching due to hyperextension of the head.
How does blood leave the brain?
The internal jugular veins are considered to be the main pathways of cerebral blood drainage. However, angiographic and anatomical studies show a wide anatomical variability and varying degrees of jugular and non-jugular venous drainage.
What is the main artery that carries blood to your lungs?
The pulmonary artery is a big artery that comes from the heart. It splits into two main branches, and brings blood from the heart to the lungs. At the lungs, the blood picks up oxygen and drops off carbon dioxide. The blood then returns to the heart through the pulmonary veins.
What causes a tear of the basilar artery in the brain stem?
Most basilar artery strokes are caused by atherosclerosis (hardening of the arteries). The second-leading cause is clots. Leading risk factors for basilar artery strokes are high blood pressure, diabetes, smoking, high cholesterol, coronary artery disease and peripheral vascular disease.
Where is the basilar artery located in the brain?
The basilar artery lies at the front of the brainstem in the midline and is formed from the union of the two vertebral arteries. The basilar artery terminates by splitting into the left and right posterior cerebral arteries.
What is basilar artery stenosis?
Intracranial stenosis is the narrowing of an artery inside the brain due to buildup of plaque inside the artery. The arteries most likely to be affected by stenosis are the internal carotid artery, the middle cerebral artery, the vertebral arteries, and the basilar artery.
