Longitudinal pulsatility in arterial occlusion

Abstract

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.

Modern diagnostics in emergency medicine

“…Ultrasound-based examinations are generally regarded as the most important non-invasive vascular imaging, with both B-mode and color Doppler providing highly reliable information [62]. In deep vein thrombosis (DVT), compression ultrasound is the most accurate non-invasive test [63].…”

“…Vascular ultrasound also plays an important role in the non-invasive assessment of occlusive diseases of the arteries. Both B-mode and Doppler methods provide information about the local conditions [62]. In addition to diagnostics, vascular imaging improves both safety and quality of puncture for central venous access in comparison to the use of anatomical features alone [68].…”
