The basilar artery (U.K.: / ˈ b æ z. ɪ. l ə /; [1] [2] U.S.: / ˈ b æ s. ə. l ər / [3]) is one of the arteries that supplies the brain with oxygen-rich blood.. The two vertebral arteries and the basilar artery are known as the vertebral basilar system, which supplies blood to the posterior part of the circle of Willis and joins with blood supplied to the anterior part of the circle of ...
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.

In medicine, the dense artery sign or hyperdense artery sign is an increased radiodensity of an artery as seen on computer tomography (CT) scans, and is a radiologic sign of early ischemic stroke. [1] In earlier studies of medical imaging in patients with strokes, it was the earliest sign of ischemic stroke in a significant minority of cases. [2]
Prognosis depends on factors like the size and location of the aneurysm and the patient’s age and health, with larger aneurysms having a higher risk of rupture and poorer outcomes. Advances in medical imaging have led to increased detection of unruptured aneurysms, prompting ongoing research into their management and the development of ...
The rate of injection is 3 to 5 ml/sec, for a total of 8ml. The fluoroscope will be catching images at a rate of 2 to 4 frames per second. [8] Posterior cerebral artery (PCA) can be seen in AP view. [8] The left vertebral artery is easier to cannulate than the right vertebral because of the straightforward anatomy of the left vertebral artery. [16]
In CAD, atheromatous plaque formation in a coronary artery limits oxygen supply to cardiomyocytes, impairing heart contractility. CAD severity varies based on the extent of coronary artery occlusion. At 75% luminal narrowing, patients experience symptoms associated with limited perfusion of cardiomyocytes, [11] especially under strenuous ...

The basilar artery is the main blood supply to the brainstem and connects to the Circle of Willis to potentially supply the rest of the brain if there is compromise to one of the carotids. At each cervical level, the vertebral artery sends branches to the surrounding musculature via the anterior spinal arteries .
