Management of carotid near-occlusion and acute carotid occlusion [PDF]
, 2016 As a stenosis becomes more severe, blood flow through it increases in velocity to maintain volume, flow and pressure. But there is a critical point beyond which further increase in stenosis no longer allows sufficient blood to pass through to maintain ...
