2. Vertebrobasilar insufficiency - Wikipedia

   en.wikipedia.org/wiki/Vertebrobasilar_insufficiency

   Atherosclerotic plaque can rupture, resulting in a source of emboli. These emboli can cause TIAs or strokes in the areas of the brain supplied by the affected artery. Where stenosis is severe, abrupt changes in blood pressure can temporarily result in inadequate flow through the stenosis, causing symptoms that are usually very brief. [6]

3. Carotid artery stenosis - Wikipedia

   en.wikipedia.org/wiki/Carotid_artery_stenosis

   The carotid artery divides into the internal carotid artery and the external carotid artery. The internal carotid artery supplies the brain. Plaque often builds up at that division and causes a narrowing (stenosis). Pieces of plaque can break off and block the small arteries above in the brain, which causes a stroke. Plaque can also build up at ...

   As a result, blood travels up one of the other blood vessels to the brain (the other vertebral or the carotids), reaches the basilar artery or goes around the cerebral arterial circle and descends via the (contralateral) vertebral artery to the subclavian (with the proximal blockage) and feeds blood to the distal subclavian artery (which ...

7. Arterial occlusion - Wikipedia

   en.wikipedia.org/wiki/Arterial_occlusion

   Normally, the blockage should affect approximately 70% of the artery for symptoms to become noticeable. [3] Symptoms can be less severe during gradual narrowing, as this allows time for the widening of existing vessels and the formation of new ones ( collateral vessels ), allowing blood to still reach the area.

9. Posterior cerebral artery syndrome - Wikipedia

   en.wikipedia.org/wiki/Posterior_cerebral_artery...

   Posterior cerebral artery syndrome is a condition whereby the blood supply from the posterior cerebral artery (PCA) is restricted, leading to a reduction of the function of the portions of the brain supplied by that vessel: the occipital lobe, the inferomedial temporal lobe, a large portion of the thalamus, and the upper brainstem and midbrain.
