Objective: To report the experience with prenatal repair of open spina bifida (OSB) from 2 centers in Chile.Methods: Women with a second-trimester fetus with OSB were offered intrauterine neurosurgical repair following the protocol from the Management of Myelomeningocele Study (MOMS) trial. Pediatric follow-up with infants reaching 12 and 30 months of life was also reviewed.Results: Fifty-eight fetuses with OSB underwent intrauterine repair at an average (±SD) gestational age of 24.8 ± 0.9 weeks. There were 3 (5.1%) intrauterine deaths. The average gestational age at delivery of the remaining 55 cases was 33.3 ± 3.6 weeks, and the average birth weight was 2,172 ± 751 g. Delivery before 30 weeks occurred in 11 cases (20.0%). Two (3.6%) neonatal deaths (<28 days) occurred. At 12 months, a ventriculoperitoneal shunt or an endoscopic third ventriculostomy was required in 25% of the cases. At 30 months, 72.4% of the infants were able to walk.Discussion: Prenatal neurosurgical repair of OSB is a complex and challenging intervention. Major complications include perinatal death and severe prematurity. No major maternal complications occurred in our series. A reduction in the need for cerebrospinal fluid diversion and an improved ability to walk seem to be the greatest long-term advantages of this procedure. [ABSTRACT FROM AUTHOR]

Objective: To determine the prevalence, sonographic spectrum, and clinical significance of echogenic material in the fetal gallbladder in our population.Methods: Sonographic visualization of the fetal gallbladder was attempted in 3894 consecutive third-trimester pregnancies (4026 fetuses). Gallbladder content was classified as clear (anechoic), containing echogenic material that was either diffuse (sludge), or presenting as a single focus or multiple foci (gallstone(s)). Information on the clinical course was obtained by reviewing the medical records or contacting the provider or the parents themselves.Results: During the three and a half-year study period from July 2014 to December 2017, 19 fetuses were identified as having echogenic material in the gallbladder (prevalence 1/211, 0.47%). Among them, echogenic biliary sludge was found in eight fetuses (42%); all eight were asymptomatic and a normal gallbladder was documented postnatally in four of them. Single (n = 3) or multiple (n = 8) echogenic foci were found in 58% of cases, which was associated with a good prognosis and subsequent resolution between 1 and 10 months of life in all cases.Conclusions: The prevalence of echogenic material in the fetal gallbladder in our population was similar to that previously reported in the literature. The prognosis appears to be favorable, with resolution and without subsequent postnatal hepatic or gastrointestinal complications in all cases. [ABSTRACT FROM AUTHOR]

Objective: To examine patient and provider attitudes toward first trimester nuchal translucency (NT) screening for Down syndrome and to assess how patients consent to screening in a country where abortion is illegal.Methods: Patients presenting for first trimester ultrasound including NT screening in two obstetric units in Chile completed a questionnaire about their attitudes toward NT screening and perspectives on the consent process. A follow-up questionnaire assessed satisfaction with the test. Prenatal care providers also completed a questionnaire ascertaining their perspectives on NT screening.Results: A total of 107 patients completed the initial questionnaire and 78 completed the follow-up questionnaire. Although 98 (94%) patients desired NT screening only 38 (38%) indicated that they would undergo diagnostic testing if they received screen positive results. Only 3 patients screened positive; however, 15 (20%) participants experienced increased anxiety after the test. Almost all of the 36 providers surveyed indicated that they counsel their patients thoroughly, but 38 (39%) patients reported that they received adequate information.Conclusion: NT screening is often performed without patients' full understanding of the implications of potential results and may cause anxiety. Providers should elicit patients' preferences regarding prenatal testing and engage them in shared decision making about whether to undergo screening, particularly when abortion is not an option.
