never attempt a venipuncture with the drug-containing syringe attached. If you have the syringe attached and enter the common carotid artery by mistake, you will not recognize the red color of the arterial blood nor its pulsations. Always insert the needle, observe venous blood, and then attach...
The NC’s influential adhesion parameters to the inner wall of atherosclerosis inside the artery, the velocity of blood flow entering the carotid artery, and the direction and magnitude of the magnetic field (Supplementary Note 6), depend on the number of NCs entering each cardiac cycle and the...
Evaluation of Pulse Wave Velocity and endothelial function test using forearm ischemia hyperhemia were performed. Analysis of plaques in left common carotid artery included, plaque area, B Hist plaque composition analysis (Grey Scale Mean GSM), V FLOW parameters speed gradient, flow, WSS and ...
For assessment of an extracranial arterial stenosis (ECAS), each participant underwent a bilateral carotid duplex sonography. ECAS was defined by a peak systolic blood flow velocity ≥125 cm/s and vertical artery peak systolic blood flow velocity of ≥170 cm/s in the common carotid artery...

(CAS) diagnosis has substantially increased over the decades, with the progressive technological developments passing from measurement of the narrowing carotid artery diameter to evaluation of the increased velocity field near the obstruction/lesion site in the carotid artery, with increased emphasis now ...
(CEA). In patients undergoing CEA for internal carotid artery stenosis (≥70%), cerebral blood flow (CBF) was measured using single-photon emission computed tomography (SPECT) before and immediately after CEA. Microembolic signals (MES) were identified using transcranial Doppler during carotid ...
o to 5% at 60 o .The majority of stenosis classification schemes are based on the peak systolic velocity (PSV) at the site of stenosis, the PSV in the common carotid artery (CCA), the end-dialostic velocity (EDV) in the CCA, PSV ratios, PSV:EDV ratios and ICA spectral broadening. ...
CAROTID artery ultrasonographyCEREBROVASCULAR diseaseATHEROSCLEROTIC plaqueBackground: The effect of anterior communicating artery (ACoA) patency on the flow velocity of the extracranial carotid arteries is unclear. Methods: A total of 285 patients with carotid artery stenosis were i...
