This pictorial essay aims to generate attention and inform sonographers and clinicians by remembering the "longitudinal pulsatility" as an evocative B-mode echographic sign of arterial occlusion, when the artery exhibits a systolic axial motion instead of its normal radial pulsatility.
Keywords: B-mode ultrasonography; arterial occlusion; longitudinal pulsatility.
