Cerebral angiography, blood flow and vascular reactivity in progressive hypertension
Chronic hypertension alters cerebral vascular morphology, cerebral blood flow (CBF), cerebrovascular reactivity, and increses susceptibility to neurological disorders. This study evaluated: i) the lumen diameters of major cerebral and downstream arteries using magnetic resonance angiography, ii) basal CBF, and iii) cerebrovascular reactivity to hypercapnia of multiple brain regions using arteri...
متن کاملInduced hypertension improves cerebral blood flow in acute ischemic stroke.
A 76-year-old man presented with fluctuating right-hand clumsiness and mild right-leg weakness. MRI revealed a left anterior cerebral artery (ACA) infarct with perfusion/diffusion mismatch. Gradient echo imaging showed a left ACA clot, and magnetic resonance angiography showed left A2 occlusion (figure, A). The patient’s symptoms recurred the next morning, when mean arterial pressure (MAP) was ...

متن کاملRegional cerebral blood flow in chronic hypertension. A correlative study.
BACKGROUND AND PURPOSE Cerebral hypoperfusion has occasionally been reported during essential hypertension. We explored regional cerebral blood flow in a large series of neurologically asymptomatic hypertensive patients to determine relations among cerebral blood flow, concomitant main vascular risk factors, and the most common signs of end-organ damage. METHODS Regional cerebral blood flow w...
متن کاملCerebral blood flow during treatment for pulmonary hypertension.
AIM To determine if the haemodynamics of systemic and cerebral circulation are changed during treatment for persistent pulmonary hypertension of the newborn (PPHN). METHODS Fifteen term newborn piglets with hypoxia induced pulmonary hypertension were randomly assigned either tolazoline infusion (Tz), hyperventilation alkalosis(HAT), and inhaled nitric oxide (iNO). Mean pulmonary arterial pres...
