What are the effects of your left vertebral artery not connecting to your basilar artery?

If the Circle of Willis can still maintain at least 50% blood pressure with the blood flow from the one good artery, then no infarctions will occur. Patients with blockage in the LVA can exist with no visable signs of illness as long as the otra continues to function properly. If the remaining VA enlarges as a result of increased blood flow, a transient ischemic attack may result, temporarily depriving the brain of oxygen.
Because the patient is now without a backup system, they are more at risk of a stoke when exhibiting low blood presure, hypertension, or arteriosclerosis.
Of course, if the left vertebral were severed via trauma, it would require surgery to repair because of the bleed into the brain would cause swelling and brain trauma.

Basilar artery is formed by the union of what two arteries?
vertebral arteries
What are the two vertebral arteries?
The vertebral arteries are branches from the subclavian arteries that travel up the spine in the foramen transversarium and into the skull in the formen magnum. They fuse at the level of the midbrain to form the basilar artery and then the posterior cerebral arteries. They supply blood to the brainstem, cerebellum and posterior portions of the brain.
Which arteries pass through the foramen magnum and then unite to form the basilar artery?
The vertebral arteries merge to form a basilar artery which form the posterior Circle of Willis. The middle cerebral arteries form the rest of the Circle of Willis.
What is the main artery that takes blood to the brain?
The left and right corotid arteries and the vertebral arteries which join together to form the basilar artery (forming the circle of willis).
What are the pathway of a drop of blood from the aorta to the left occipital lobe of the brain and What are the structures through which it flow?
The drop of blood travels as follows: From the aortic arch to the left subclavian artery. Then through the left vertebral, passing though the transverse foramina of the cervical vertebrae (from C6-C1) At the C1 level the vertebral arteries travel across the posterior arch of the atlas before entering the foramen magnum into the skull. From here, it merges with with that vertebral artery on the right side to become the basilar artery. The blood then travels through a branch of the basilar known as the posterior cerebral artery. This artery's branches are divided into two sets, the ganglionic branches and, the cortical branches. The particular artery largely supplying the occipital lobe is known as the parietoöccipital or parieto-occipital artery, and is a cortical branch.

Which vessel is formed when the vertebral arteries join together at the base of the skull?
The right and left vertebral arteries join together to form a single basilar artery at the base of the skull.
What happens when to blood as it passes through brain?
vertebral arteries pass through foramen magnum and reach the inferior of the brain & unite to from the basilar artery. The vertebral artery supplies the posterior of the brain. Basilar atery branches into posterior cerebral artery & cerebellar arteries that supply the cerebellum & pons. Common carotid arteries divide & the internal carotid supplies structures internal to the skull
What is basilar migraine?
Basilar Migraine is a type of migraine that affects the basilar artery of the brain.

What is the blood vessel in the space anterior to the pons?
basilar artery.
