(OR = 9.7; p = 0.04). Another analysis comparing elective cesareans and vaginal deliveries also showed an increased risk for cesarean (OR = 4.7; p = 0.02). Finally, comparing elective cesareans with trial of labor, we found an increased proportion of complications in elective cesareans, with borderline significance (OR = 3; p = 0.058). We concluded that cesarean section is associated with maternal morbidity, even after controlling for confounders.
Objective Labor induction does not always result in vaginal delivery, and can expose both the mother and the fetus to the risks inherent to the induction procedure or a possible cesarean section. Transvaginal sonography (TVS) of the cervix is a useful tool to predict prematurity; in the present study, this tool was used to evaluate postterm induction. Methods We evaluated the ultrasound characteristics of the cervix (cervical length, cervical funneling, internal os dilation, the presence or absence of the cervical gland area [CGA], and the morphological changes of the cervix as a result of applying fundal pressure) before the onset of labor induction among women with postterm pregnancy to identify the possible predictors of failed labor induction. The Bishop score (BS) was used for comparison purposes. Three groups were evaluated: successful versus unsuccessful induction; vaginal delivery versus cesarean delivery (excluding cases of acute fetal distress [AFD]); and vaginal delivery versus cesarean delivery (including cases of AFD). A fourth group including only the primiparous women from the three previous groups was also evaluated. Results Based on the studied characteristics and combinations of variables, a cervical length ≥ 3.0 cm and a BS ≤ 2 were the best predictors of induction failure. Conclusion Although TVS is useful for screening for induction failure, this tool should not be used as an indication for cesarean section.
a more accurate prognosis for each case. MRI was very useful in all cases allowing a greater definition and accuracy in estimating the size of the abdominal wall defect. We describe 14 cases of omphalocele diagnosed by real-time sonography and submitted to magnetic resonance imaging on the third trimester. This exam allowed a precise and accurate definition of the size of the abdominal orifice, as well as the contents inside and outside the abdominal cavity and the detection of associated anomalies. The three dimensional images obtained with MRI were very useful for the neonatal surgeons in planning their intervention and counseling parents about the prognosis of their infant. MRI contributes significantly to optimize the prenatal management and counseling of cases of omphalocele. P43.11 MRI and 3D-US in placenta accreta: Comparison of results Placenta accreta describes an abnormally adherent placenta which extends through the myometrium. Important predisposing factors are placenta previa and uterine scar from previous cesarean section. The risk exceeds 50% in women with placenta previa and multiple cesarean deliveries. We report a series of 5 cases of placenta previa and hypothesis of placenta accreta/percreta. All patients realized a Magnetic Resonance Imaging (MRI) exam and a three-dimensional ultrasound (3-D US), using the power Doppler feature with less than 48 hour interval. All five patients were submitted to a cesarean-hysterectomy with prior internal iliac catheterization. The histopathological findings were compared to the MRI and 3D-US results in table 1. Cases 3D-US MRI Pathology 1 placenta previa accreta placenta previa accreta placenta previa increta 2 placenta previa percreta placenta previa percreta placenta previa increta 3 placenta previa percreta placenta previa accreta placenta previa percreta 4 placenta previa accreta placenta previa accreta placenta previa increta 5 placenta previa accreta placenta previa percreta placenta previa increta In our cases, the combined data acquired from MRI and 3-D US contributed to the diagnosis and allowed a better operatory planning and risk management. Both exams were able to show an invasive placenta, but the differentiation between accreta, increta and percreta was not precise, with 3D-US tending to show more reliable results. P43.12 Prenatal diagnosis of giant multiloculated arachnoid cyst: US and ultrafast MRI study Objective: To demonstrate the utility of fetal ultrafast MRI in the evaluation of sonographically equivocal intracranial cysts. Materials and methods: Two and three dimensinonal sonography and doppler study were used to scan a 23 years old case at 31 gestational age. Ultrafast MRI was added as a complementary dignostic modality. Results: US demonstated a living male singleton pregnancy with a giant multiloculated left middle cranial fossa cystic lesion with suspected communication with the ipsilateral ventricle. The lesion was extending into the subtemporal and posterior cranial fossa with considerable mass effect and mid line shift. Doppler...
