Evaluation of Portal, Splenic, and Hepatic Vein Flows in Children Undergoing Congenital Heart Surgery
Authors' conclusion
The characteristics of venous Doppler patterns in the portal, splenic, and hepatic veins differed according to congenital heart disease.
Study context
- Population
- Children undergoing cardiac surgery, tertiary children's hospital
- Participants
- 246 vs 77
- Exposure
- Biventricular vs Single-ventricle
- Biventricularn = 246
- Single-ventriclen = 77
- Outcome
- Portal, splenic and hepatic vein flow patterns by ultrasonography before and after surgery

Main finding
As reported in the abstract
Portal, splenic and hepatic vein Doppler characteristics
- Biventricular: portal pulsatility index before vs after surgery
- 38.7% to 25.6% (p < 0.001)
- Biventricular: preoperative portal pulsatility index, pulmonary hypertension vs not
- 43.3% v 27.4%; p < 0.001
- Single-ventricle: maximum portal vein flow velocity, Fontan vs modified Blalock-Taussig shunt
- 13.5 cm/s vs 19.7 cm/s; p = 0.035
- Single-ventricle: maximum portal vein flow velocity, Fontan vs bidirectional cavopulmonary shunt
- 13.5 cm/s vs 23.1 cm/s; p < 0.001
- Cardiac index inversely correlated with portal pulsatility index in bidirectional cavopulmonary shunt and Fontan circulation
- β = −5.693, r2 = 0.473; p = 0.001
Observational data: associations, not effects.
