Abstract
Objective:
A current descriptive assessment of perinatal outcomes in pregnancies complicated by previable preterm premature rupture of membranes (pPPROM) at <24 weeks of gestation, after expectant treatment.
Study design:
Maternal and short-term neonatal data were collected for patients with pPPROM.
Results:
Seventy-three patients with 93 fetuses were hospitalized with pPPROM at 15–24 weeks’ gestation. Among these patients, 27.4% (n=20) chose pregnancy termination, 27.4% (n=20) miscarried and 45.2% (n=33) proceeded to live births. After a median latency period of 38 days, ranging from 1 to 126 days, 24 singletons and 20 multiples were live-born, of whom 79.5% (n=35) survived the perinatal period. The main neonatal sequelae were pulmonary hypoplasia (29.5%; n=13), connatal infection (56.8%; n=25), intraventricular hemorrhage (25%; n=11; resulting in five neonatal deaths) and Potter’s syndrome (15.9%; n=7). Nine newborns died, within an average of 2.8 days (range, 1–10 days). The overall neonatal survival rate was 51.5% – including miscarriages but not elective terminations. The intact survival rate was 45.5% of all live-born neonates.
Conclusions:
Even with limited treatment options, overall neonatal survival is increasing. However, neonatal mortality and morbidity rates remain high. The gestational age at membrane rupture does not predict neonatal outcome.
