Objective:
This study compared insertion difficulties, shunt failure, reintervention rates, maternal adverse events, and neonatal outcomes among different shunt types used in fetal hydrothorax.
Method:
A retrospective multicenter cohort study (2012-2022) was conducted across 12 international centers. The primary outcome was the occurrence of complications, classified as insertion difficulties and shunt failure (dislocation, occlusion, or unexplained shunt failure). Secondary outcomes included reintervention rates, maternal complications, and neonatal survival.
Results:
Among 349 cases, 345 were included in the analysis of the outcome measures. Rodeck shunts had significantly fewer complications (19.5%) compared to Somatex (38.3%, OR 2.53, p = 0.016) and Harrison shunts (50.0%, OR 3.82, p < 0.001). Somatex shunts had the highest rate of incorrect positioning (16%), while dislocation was most frequent with Harrison shunts (31.1%). Reintervention rates were lowest for Rodeck (12.1%) and highest for Harrison (32.2%). Maternal body mass index, fetal hydrops, laterality and year of shunt placement did not significantly influence complication rates. No significant differences in live birth rates or gestational age at delivery were observed.
Conclusions:
The Rodeck shunt was associated with fewer insertion difficulties, better shunt performance and lower reintervention rates. There was no difference in perinatal survival among the three shunt types.
