... and PCI. Results: NVAFV showed a significant correlation with cerebral blood flow, mean transmit time, and time to peak. In the large artery atherosclerosis mechanism, a reduction in NVAFV correlated with a gradual rise in PCI cases ( p = 0.002), while this trend lacked significance in the branch artery...

... of the anterior cerebral artery ipsilateral to the symptomatic ICA occlusion [ 17 ]. Collateral flow via the PCoA was considered present if TCD showed a higher blood flow velocity in the P1 segment of the posterior cerebral artery compared with the middle cerebral artery on the side of the symptomatic ICA...

...Frederick M. Ivey; Andrew W. Gardner; C. Lynne Dobrovolny; Richard F. Macko Background: Previous studies comparing paretic limb blood flow with the unaffected limb have been contradictory and have often omitted comparisons of peak reactive hyperemic flow. Our objective was to perform bilateral...

... Blood flow Ultrasonics Human studies The consistency of a relationship between arterial remodeling and lumen diameter across 5 of the 6 carotid segments (except right bifurcation) suggests the operation of a uniform underlying physiological mechanism. This putative mechanism operates similarly...

.... Angiography Atherosclerosis Carotid arteries Blood flow In both the carotid and the coronary circulations, acute thrombotic and thromboembolic events are usually due to unstable atherosclerotic plaque [ 1, 2, 3, 4, 5, 6 ]. However, it is uncertain which factors influence the stability of plaques...

...Robert S. Reneman; Arnold P.G. Hoeks; Frans van de Vosse; David Ku In this report, the issues discussed at a multidisciplinary symposium on blood flow in bifurcations are summarized. Topics addressed are (1) flow analysis in in vitro models, using visualization and laser Doppler anemometer...
