Venous Excess Ultrasound Score prototypes combining inferior vena cava (IVC) measurements to pulse-wave Doppler patterns in the hepatic vein, portal vein and intra-renal veins. Portal Doppler is considered mildly abnormal when a variation in the velocities during the cardiac cycle of 30 to <50% are observed while is considered severely abnormal when a variation of more than 50% is seen. Hepatic Doppler is considered mildly abnormal when the systolic component is lower in magnitude than the diastolic component but still toward the liver while it is considered severely abnormal when the S component is reversed (toward the heart). Intra-renal venous Doppler is considered mildly abnormal when it is discontinuous with a systolic and diastolic phase while is it considered severely abnormal when it is discontinuous with only a diastolic phase seen during the cardiac cycle. S: systole, D: diastole
