L’échographie de la veine jugulaire interne dans l’évaluation de la volémie : une étude descriptive

Abstract : The objective of this study is to find a correlation between internal jugular vein (IJV) sonography and left ventricular filling pressure (LVFP) and a threshold to predict LVFP. A sample of 54 patients were included in 2 hospitals in Nice and 1 hospital in France from September 2020 to June 2021.
IJV diameter was measured at inspiration and expiration in a patient lying down at 45° before realizing an echocardiography which allowed to determine two groups : normal and elevated LVFP. The ratio IJV/common carotid was also calculated.
The median of RIJV diameter during inspiration was 0.30cm [0.1-0.99] for the normal LVFP group and 1.26cm [0.74-1.56] in the elevated LVFP group with significant difference (p<0.001).
A threshold lower than 0.59cm for IJV diameter was predictive of normal LVFP with a sensibility of 62% and specificity of 88%. A threshold greater than 1.08cm was predictive of elevated LVFP with a sensibility of 64% and specificity of 86%.
The ratio of RIJV/common carotid found similar results but measures during expiration and with the LIJV do not seem to be useful in practice.
Conclusion: right internal jugular vein ultrasound appeared to be helpful for extracellular assessment with a sensibility of 60-65% and a specificity >80%.
