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.
