Successful treatment of severe intra-amniotic inflammation and cervical insufficiency with continuous transabdominal amnioinfusion and cerclage: A case report

Severe intra-amniotic inflammation, even with a negative bacterial culture, can lead to premature labor. We report a 43-year-old multiparous woman with severe intra-amniotic inflammation and cervical insufficiency at 23 weeks and 5 days of gestation. Continuous transabdominal amnioinfusion was started 2 days after the diagnosis. The amniotic fluid interleukin-6 level normalized after 2 days of treatment. She underwent Shirodkar cervical cerclage on day 7. Despite termination of amnioinfusion and catheter removal on day 16, the pregnancy was maintained without any subsequent treatment. At 33 weeks and 5 days of gestation, an intrauterineUreaplasma parvuminfection and the onset of contractions led to repeat cesarean delivery. The birth weight was 2292 g, and the Apgar scores were 8/8. Both mother and infant had good outcomes. Continuous transabdominal amnioinfusion may have eliminated factors causing intra-amniotic inflammation, thereby prolonging the pregnancy and improving the infant's prognosis.
