Vasa previa y corioamnionitis: imágenes de un riesgo continuo / Vasa previa and chorioamnionitis

We are presenting a case of vasa previa diagnosed at 22 week’s gestation and then she started with threatened premature labor on week 27th.In spite of attempted tocolysis, labor continued to painless fully dilatation, spontaneous rupture of membranes, umbilical cord prolapse and unexpectedvaginal delivery of a 760 g baby in good conditions. Gross placental examination was in agreement with ultrasound findings and microscopic study demonstrated chorioamnionitis and funisitis associated to vasa previa and prematurity. We consider series of facts that happened in this case as a continuous risk condition from the morbidity to the epilog like “near miss perinatal case”. We discuss the importance of chance in the resultand we think that the preventive intervention was in the medical management and not in the attention system.

Se presenta un caso clínico de vasa previa diagnosticada con ultrasonido a las 22 semanas que evolucionó con amenaza de parto prematuro en semana 27. Pese a la frenación inicial se produjodilatación completa en forma silenciosa, rotura de membranas, procidencia de cordón y parto vaginal sorpresivo de un prematuro de 760 gramos que tuvoevolución favorable. El examen macroscópico placentario fue concordante con las imágenes observadas con ultrasonido y el estudio histológico confirmó corioamnionitis y funisitis asociadas a la vasa previa y la prematurez. La interpretación de la secuencia de eventos es de un riesgo continuo desde su inicio como morbilidad y su epílogo de probable mortalidad perinatal (“near miss”).Se discute la importancia del azar en la evolución y se concluye que una intervención preventiva estuvo en el ámbito del manejo médico y no en el sistema de atención.

Term prelabor rupture of membranes: management and outcome

To review the management of term prelabour rupture of membranes and its outcome. Interventional and descriptive. Military Hospital Rawalpindi from 10th June 2002 to 9th March 2003. 110 patients including both primigravidas and multigravidas with singleton pregnancy having term prelabour rupture of membranes were recruited by convenience sampling. They did not have any other complicating factor. They were managed according to their Bishop's score either expectantly or actively by inducing them. 64.54% of patients went into spontaneous labour within 24 hours and only 35.45% required active intervention. Deliveries by the vaginal route were 89.2% with 61% normal and 28.20% instrumental. Cesarean section rate was 10.90%, higher in those induced and primigravidas as compared to the expectantly managed and multigravidas. Chorioamnionitis was seen in 5.45% cases, 3.6% developed postpartum fever, 1.8% wound infection with no case of endometritis or neonatal mortality. 43.64% neonates were put on antibiotics but significant infection was seen in 5[4.54]% cases. Both active and expectant management are equally effective with a significant percentage delivering vaginally. However the cesarean rate was higher among the actively managed
