Pulsation of the fetal splenic vein - a potential ultrasound marker of histological chorioamnionitis and funisitis in women with preterm prelabor rupture of membranes

Abstrakt
The fetal spleen in involved in the response to intrauterine infection and inflammation. The flow pattern of its vein is not pulsatile in normal conditions.
The aim of the study was to determine whether the presence of histological chorioamnionitis and funisitis is associated with a continuours or pulsatile flow pattern in the fetal splenic vein. We performed a prospective study including 79 women with preterm prelabor rupture of membranes.
We found a relation between pulsation in the splenic vein and histological chorioamnionitis (likelihood ratio 13.2), as well as funisitis (likelihood ratio 5.7). Ultrasound evaluation of the splenic vein could be a non-invasive tool for the prediction of these inflammatory complications.
