"To an extent, an increased degree (% occlusion) of stenosis corresponds to increased PSV and EDV 4. In near-occlusion (>99%), flow velocity indices become unreliable (may be high, low or absent) 4. In this setting, a significant reduction in post-stenotic flow velocity is termed “trickle flow” 5. In complete occlusion, PSV and EDV are absent 4."
