Abstract Splenic Doppler impedance indices are measurements of splenic congestion in chronic liver disease. It is not known whether they can also assess splenic congestion in patients affected by right-sided or congestive heart failure. We analyzed splanchnic hemodynamics with Doppler ultrasound and systemic hemodynamics with right-sided heart catheterization in patients with heart failure. Splenic pulsatility index (PI) was higher in patients with heart failure (48 patients) compared with healthy subjects (39 patients) (1.19 ± 0.41 vs. 0.73 ± 0.11, p < 0.0001) and was related to hepatic vein diameter (p = 0.02). Splenic PI was not related to systemic arterial pressure, cardiac output, systemic vascular resistance or splenic arterial resistance, whereas it was related to right atrial mean pressure (p = 0.0003) and to right ventricle end-diastolic pressure (p = 0.011) (34 patients). In conclusion, splenic PI is a measurement of splenic congestion caused by an increase in venous outflow resistance. It can estimate splenic congestion in patients with right-sided or congestive heart failure.

Abstract

Abstract Splenic Doppler impedance indices are measurements of splenic congestion in chronic liver disease. It is not known whether they can also assess splenic congestion in patients affected by right-sided or congestive heart failure. We analyzed splanchnic hemodynamics with Doppler ultrasound and systemic hemodynamics with right-sided heart catheterization in patients with heart failure. Splenic pulsatility index (PI) was higher in patients with heart failure (48 patients) compared with healthy subjects (39 patients) (1.19 ± 0.41 vs. 0.73 ± 0.11, p < 0.0001) and was related to hepatic vein diameter (p = 0.02). Splenic PI was not related to systemic arterial pressure, cardiac output, systemic vascular resistance or splenic arterial resistance, whereas it was related to right atrial mean pressure (p = 0.0003) and to right ventricle end-diastolic pressure (p = 0.011) (34 patients). In conclusion, splenic PI is a measurement of splenic congestion caused by an increase in venous outflow resistance. It can estimate splenic congestion in patients with right-sided or congestive heart failure.
