Conservative management of placenta previa complicated by abnormal placentation.

OBJECTIVE: Abnormal implantation of placenta previa is life-threatening condition. The purpose of this study was to evaluate the impact of the conservative management of pregnancies with such complication on maternal morbidity rate and the chance for uterine preservation (fertility). METHODS: Eleven patients with abnormal implantation of placenta previa were analyzed prospectively. This complication was diagnosed antenatally by two-dimensional ultrasound and color flow Doppler. The following outcomes were analyzed: need for blood transfusion, admission and duration of stay in intensive care unit, infections, coagulopathies, time between cesarean section and delivery of placenta, hysterectomy and preservation of uterus. RESULTS: Among the 20 085 women who had a singleton gestation, 11 (0.054%) were identified with placenta previa with abnormal placentation. In five patients (group A), hysterectomy was performed because of hemorrhage or placenta ablation. In six patients (group B), conservative management succeeded and placenta were preserved. In group A, placenta were delivered earlier (2 d-8 weeks) in comparison with group B (6-15 weeks). Estimated blood loss during the delayed delivery of placenta was higher in the group with hysterectomy (respectively, 450-1600 and 300-500 ml). CONCLUSIONS: Conservative management of placenta previa with abnormal implantation decreases the risk of severe hemorrhage at the time of delivery and can preserve fertility.

Blood flow changes in dichorionic twins with growth discordance.

AIM: The study evaluated the applicability of Doppler ultrasonography in predicting the course of pregnancy and neonatal outcome in dichorionic pregnancy complicated by growth discordance. METHODS: Doppler examination of the umbilical artery (UA) and middle cerebral artery (MCA) was performed in 106 twins. Abnormal values of the UA pulsatility index (PI) were considered to be above the 95th percentile and below 5th percentile for the MCA PI for gestational week. The difference of UA PI ~0.5 in twin pairs was considered abnormal. Doppler results were compared with selected parameters that characterize the course of pregnancy and fetal outcome. RESULTS: Abnormal UA PI as well as the intertwine PI difference of 0.5 and more correlated significantly with lower gestational age at delivery, intertwine growth discordance of 35% or more, lower birth weight, and abnormal fetal outcome. The abnormal cerebra-umbilical(C/U) ratio correlated statistically with lower birth weight, abnormal fetal outcome, and an increased risk of premature delivery. There were no statistically significant differences in the majority of parameters that characterize the neonatal outcome between the groups with normal and abnormal MCA Pl. CONCLUSION: The intertwine UA PI difference ~0.5 had the highest predictive value in the assessment of adverse fetal outcome and risk for small for gestational age (SGA). Relatively poor sensitivity was noted with regard to the abnormal values of UA PI and C/U ratio. The worse correlation was found in case of MCA Pl.

Variable outcome in quintuplets pregnancy based on obstetric care.

The incidence of multiple pregnancies has increased dramatically over the last few years in developed countries, largely attributed to delayed childbearing and the increasing use of assisted reproduction technologies and ovulation inducing hormones. Relatively few countries have population-based statistics covering birth statistics. Of those that do, the numbers of quintuplet pregnancies rose sharply in the nineties while, at the same time, their delivery rates decreased greatly because of the use of fetal reduction. Fetal reduction is not possible or legal in some countries, Poland being one of them, and therefore obstetricians are faced with the challenges of quintuplet deliveries. Conservative treatment and management is difficult, and outcomes often vary greatly. Despite this, expert care provided at tertiary care centers can positively influence outcomes. The objective of this article is to present different care options and their consequences in two illustrative cases, as well as to establish a set of obstetric care and management goals that would allow prolongation of the gestation time. Quintuplet pregnancy is rare but poses relevant clinical problems to both the obstetrician and the neonatologist. It should be managed with close cooperation between all concerned. Due to the extreme and invariable risk of premature delivery associated with quintuplet pregnancies, we recommend early diagnosis, adequate prenatal care at one tertiary medical center, routine hospitalization and bed rest, repeated ante partum ultrasound surveillance with tests of fetal well-being, tocolytic therapy at first signs of the risk of premature labor, and specialized neonatology care after delivery.
