Renal artery stenosis stenosis is longstanding and severe, the glomerular filtration rate in the affected kidneys never recovers and (prerenal) kidney failure is the result. Changes include: The diagnosis of renal artery stenosis can use many techniques to determine if the condition is present, a clinical prediction rule is available to guide diagnosis. Among the diagnostic techniques are: It is initially treated with medications, including diuretics, and medications for blood pressure control. When high-grade renal artery stenosis is documented and blood pressure cannot be controlled with medication, or if renal function deteriorates, surgery may be resorted to. The most commonly used procedure is
Basilar artery ventral to the pons and divides at the ponto-mesencephalic junction into the paired posterior cerebral arteries close to the pituitary stalk. Its branches can be divided into two groups: A basilar artery stroke classically leads to locked-in syndrome. Basilar artery In human anatomy, the basilar artery is one of the arteries that supplies the brain with oxygen-rich blood. The two vertebral arteries and the basilar artery are sometimes together called the "vertebrobasilar 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 Willis from
