We aimed to compare internal jugular vein and inferior vena cava ultrasonography as predictors of central venous pressure in cirrhotic patients. We performed ultrasound assessments of the IJV and the IVC and then invasively measured CVP. We then compared their correlation with CVP and performed AUROC curves to determine which had best sensitivity and specificity. IJV CSA-CI at 30º correlated better with CVP (r=-0.56, P=<0.001), and an IJV AP-CI at 30º ≤24.8% was better at predicting a CVP ≥8 mmHg, with 100% sensitivity and 97.1% specificity. Thus, IJV POCUS might be superior than IVC POCUS as a predictor of CVP in cirrhotic patients.
