Cerebral blood flow pulsatility and cerebral artery stiffness acutely decrease during hemodialysis

Physiological Reports, 2023
End‐stage kidney disease (ESKD) is associated with increased arterial stiffness and cognitive impairment. Cognitive decline is accelerated in ESKD patients on hemodialysis and may result from repeatedly inappropriate cerebral blood flow (CBF). The aim of

Transcranial Color‐Coded Duplex Sonography in Large‐Vessel Vasculitis Compatible With Takayasu Arteritis Presenting Intracranial Involvement and Vertebrobasilar Dolichoectasia: A Case Report

Journal of Clinical Ultrasound, EarlyView.
This case illustrates sequential intracranial occlusions in large‐vessel vasculitis compatible with Takayasu arteritis preserving perfusion through robust collateral pathways. Transcranial color‐coded duplex sonography identified characteristic blunted flow patterns and focal turbulence, underscoring its value in detecting hemodynamic compromise beyond

Hemodynamic changes of severe carotid atheromatosis pre and post endarterectomy in the case of a coronary patient with ischemic stroke [PDF]

Romanian Journal of Neurology, 2013
Nearly 25%-30% of ischemic strokes are due to atherosclerosis of the carotid bifurcation. Cerebrovascular reactivity (CVR) is an indicator for testing hemodynamic status of cerebral circulation.

Identification of predictive factors for reversal of cerebral vasculopathy in an original longitudinal cohort study in newborns with sickle cell anaemia

British Journal of Haematology, EarlyView.
Summary Cerebral macrovasculopathy (CV) is a major complication in children with sickle cell anaemia (SCA) and usually requires a long‐term transfusion programme (TP) to prevent stroke. This study aimed to identify factors predicting reversal of CV on TP in a single‐centre newborn cohort. Among 375 patients, 50 presented CV and received TP.
