Vertebrobasilar insufficiency (VBI) is reduced or stopped blood flow to the back of your brain. Hardening of your arteries (atherosclerosis) often causes this condition. VBI impacts your balance and movement, as well as increases your risk of stroke and other health issues.

2023年7月17日 · Vertebrobasilar insufficiency (VBI) is defined by inadequate blood flow through the posterior circulation of the brain, supplied by the 2 vertebral arteries that merge to form the basilar artery. The vertebrobasilar arteries supply the …

椎基底動脈供血不足 (Vertebrobasilar insufficiency, VBI)，又稱椎基底動脈循環不全，是導致中樞性眩暈和老人眩暈之常見因素。 椎基底動脈是負責供應腦幹、小腦、丘腦及枕葉營養的重要血管，若異常則會影響人體自主神經系統 (如呼吸，心率等)、意識、協調、平衡 ...

Vertebrobasilar insufficiency (VBI) describes a temporary set of symptoms due to decreased blood flow (ischemia) 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] .

Understanding the anatomical pathways and clinical presentations for VBI are of the utmost importance due to the potential mimics that may occur. After identification of the entity, imaging must be performed to identify the etiology.

Vertebrobasilar Insufficiency (VBI) occurs as a result of poor circulation to the posterior region of the brain due to the occlusion of the vertebral or basilar arteries. Clinical Relevant Anatomy [ edit | edit source ]

The most common cause of VBI is atherosclerosis, therefore, the aim of this systematic review is to identify the reported signs and symptoms of patients with a confirmed diagnosis of atherosclerotic induced VBI.
