However, at this level, the left common carotid artery is very close to the carotid that could be affected during the manipulation. This study aimed to assess the hemodynamic effects of LPP on the carotid blood flow.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We prospectively included 47 healthy adult volunteers. We excluded pregnant women and people with anomalies of the carotid arteries. The common and internal carotid arteries were preliminarily studied with ultrasounds to exclude atheromatous plaques or vascular malformation. A planimetry of the common and internal carotid arteries was performed. Doppler echography served to measure the peak systolic (PSV) and end\u2010diastolic velocities (EDV) in the common and internal carotid arteries. All measurements were repeated while applying LPP.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Forty\u2010seven participants were enrolled (32 women; mean [SD] age: 42 [13] years).<\/jats:p><jats:p>The mean PSV difference [95% CI] in the left common carotid artery before and after LPP at the group level was \u221215.30 [\u221231.09 to 0.48] cm s<jats:sup>\u22121<\/jats:sup> (<jats:italic>p<\/jats:italic>\u2009=\u2009.14).
