Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow in the posterior circulation of the brain. The posterior circulation supplies the medulla , pons , midbrain , cerebellum and (in 70-80% of people) supplies the posterior cerebellar artery to the thalamus and occipital cortex . [ 1 ]
Besides, overuse injury of the upper limbs causes swellings, small bleeding, and subsequent fibrosis which would cause the thrombosis of the subclavian vein, leading to Paget–Schroetter disease or effort-induced thrombosis. [7] TOS can be related to cerebrovascular arterial insufficiency when affecting the subclavian artery. [8]
TOS has been reported to cause stroke through theorized clot propagation towards the vertebral artery; [3] a similar mechanism could explain how TOS causes SSS. Presence of a cervical rib is a risk factor for both TOS and SSS. [citation needed] Takayasu's arteritis is a disease causing inflammation of arteries, including the subclavian artery ...
A rare but severe complication of this disease is vertebrobasilar insufficiency. [7] This is a result of the vertebral artery becoming occluded as it passes up in the transverse foramen. The spinal joints become stiff in cervical spondylosis. Thus the chondrocytes which maintain the disc become deprived of nutrition and die.
vertebrobasilar insufficiency; optic neuritis; visual snow syndrome; Vitreous shrinkage or liquefaction, which is the most common cause of photopsia, causes a pull in vitreoretinal attachments, irritating the retina and causing it to discharge electrical impulses.
“Drinking less over time can have really measurable benefits in your health in terms of your blood pressure, your risk of cancer, your risk of liver disease and other conditions,” Wakeman said.
Posterior circulation infarct (POCI) is a type of cerebral infarction affecting the posterior circulation supplying one side of the brain.. Posterior circulation stroke syndrome (POCS) refers to the symptoms of a patient who clinically appears to have had a posterior circulation infarct, but who has not yet had any diagnostic imaging (e.g. CT Scan) to confirm the diagnosis.
The agency noted that "diet-related chronic diseases in the U.S. are the leading causes of death and disability." The FDA explained that the move will help call attention to products like nuts and ...
