Absent or reversed end-diastolic flow in the umbilical artery: outcome at a community hospital.
OBJECTIVE
To describe the peripartum outcome and risk factors for neonatal death among pregnancies complicated with umbilical arterial absent end diastolic or reverse flow (AREDF UA), in a community hospital.


METHODS
The inclusion criteria of this retrospective analysis were: AREDF UA detected and managed at a community hospital.


RESULTS
During the 46 months, 50 cases of AREDF UA were detected and the pregnancies were complicated by hypertensive disease in 52%, twins in 26%, and diabetes mellitus in 14%. Excluding four (8%) stillbirths of non-anomalous fetuses, nine newborns died and the significant differences between those who died and lived (n = 36) were: oligohydramnios (odds ratio [OR] 34.00, 95% confidence intervals [CI] 4.65, 248.50), non-immune hydrops (OR 24.33, 95% CI 1.01, 560.60) and respiratory distress syndrome (OR 7.00, 95% CI 1.27, 38.59).


CONCLUSIONS
The risk factors for neonatal mortality with AREDF UA are oligohydramnios, non-immune hydrops, or respiratory distress syndrome.
