RESUMO

INTRODUCTION: In fetal surgery, successful pain management is crucial for postoperative mobilization, prophylaxis of contractions, and fast recovery. This study analyzed patient's pain experience after open fetal spina bifida (fSB) repair in comparison to pain scores after the subsequent Caesarean section (C-section). MATERIALS AND METHODS: Data was collected with a questionnaire given to 91 women, who had fSB repair and then C-section at our center between 2019 and 2022. It comprised 12 questions covering different aspects of pain experience and satisfaction with pain therapy and was answered by 67 women after fSB repair and 53 after C-section. Postoperative pain was rated on a Likert scale from 0 (slight/rarely) to 100 (strongest/always). Outcomes after fSB repair were compared to those after C-section. Additionally, subgroup analysis compared outcomes of women with different pain levels (group 1-5) after fSB repair. RESULTS: Compared to women after C-section women after fSB repair reported significantly higher maximum pain scores (MPS) (p = 0.03), higher sleep disturbance due to pain (p = 0.03), and sedation rates (p = 0.001) as side effect from pain therapy. No differences were found regarding feelings of insecurity (p = 0.20) or helplessness (p = 0.40), as well as involvement in (p = 0.3) and satisfaction with pain therapy (p = 0.5). Subgroup analysis revealed that women with higher MPS after fSB repair were significantly more often non-Caucasians (p = 0.003) and more often affected by pain while lying in bed (p = 0.007) and during mobilization (p = 0.005). Additionally they reported higher rates of dizziness (p = 0.02) and lower satisfaction rates with pain therapy (p = 0.03). Postoperative complication rate did not differ among groups. CONCLUSION: Although women after fSB repair reported higher MPS compared to after C-section, the current pain management was generally perceived as satisfactory.

RESUMO

INTRODUCTION: For open fetal spina bifida (fSB) repair, a maternal laparotomy is required. Hence, enhanced maternal recovery after surgery (ERAS) is paramount. A revision of our ERAS protocol was made, including changes in operative techniques and postoperative pain management. This study investigates eventual benefits. METHODS: Our study included 111 women with open fSB repair at our center. The old protocol group (group 1) either received a transverse incision of the fascia with transection of the rectus abdominis muscle (RAM) or a longitudinal incision of the fascia without RAM transection, depending on placental location. The new protocol required longitudinal incisions in all patients (group 2). Postoperative pain management was changed from tramadol to oxycodone/naloxone. Outcomes of the two different protocol groups were analyzed and compared regarding the primary endpoint, the length of hospital stay (LOS) after fetal surgery, as well as regarding the following secondary endpoints: postoperative pain scores, day of first mobilization, removal of urinary catheter, bowel movement, and the occurrence of maternal and fetal complications. RESULTS: Out of 111 women, 82 (73.9%) were in group 1 and 29 (26.1%) were in group 2. Women in group 2 showed a significantly shorter LOS (18 [14-23] days vs. 27 [18-39] days, p = 0.002), duration until mobilization (3 [2-3] days vs. 3 [3-4] days, p = 0.03), and removal of urinary catheter (day 3 [3-3] vs. day 4 [3-4], p = 0.004). Group 2 less often received morphine subcutaneously (0% vs. 35.4%, p < 0.001) or intravenously (0% vs. 17.1%, p = 0.02) but more often oxycodone (69.0% vs. 18.3%, p < 0.001). No significant differences were seen regarding pain scores, bowel movement, and maternal and/or fetal complications. CONCLUSION: The new ERAS protocol that combined changes in surgical technique and pain medication led to better outcomes while reducing LOS. Continuous revisions of current ERAS protocols are essential to improve patient care continuously.

RESUMO

INTRODUCTION: The Management of Myelomeningocele Study (MOMS) eligibility criteria preclude in utero surgery for fetal spina bifida (fSB) when the maternal body mass index (BMI) is ≥35 kg/m2. Some centers still respect this criterion, while others, like ours, do not. This study aimed to assess whether maternal and fetal safety is compromised with higher maternal BMIs. METHODS: Data of 192 patients with open fSB repair at our center were retrospectively analyzed. According to their BMI, patients were divided into three groups: group 1 (BMI <30 kg/m2), group 2 (BMI 30-35 kg/m2), and group 3 (BMI >35 kg/m2). Subgroup analysis was performed to assess differences in maternal and fetal outcomes. Additionally, complications were divided into grades 1 to 5 according to their severity and outcome consequences and compared among groups. RESULTS: Out of 192 patients, 146 (76.0%) had a BMI <30 kg/m2, 28 (14.6%) had a BMI 30-35 kg/m2, and 18 (9.4%) had a BMI >35 kg/m2. Significant differences occurring more often in either group 2 or 3 compared to group 1 were maternal wound seroma (50% or 56% vs. 32%, p = 0.04), amniotic fluid leakage (14% or 6% vs. 2%, p = 0.01) as well as vaginal bleeding (11% or 35% vs. 9%, p = 0.01). On the contrary, duration of tocolysis with atosiban was shorter in patients with BMI >30 kg/m2 (4 or 5 vs. 6 days, p = 0.01). When comparing severity of maternal or fetal complications, grade 1 intervention-related complications occurred significantly more often in group 3 compared to group 1 or 2 (78% vs. 45% or 57%, p = 0.02). Gestational age at delivery was around 36 weeks in all groups without significant differences. CONCLUSION: This investigation did not identify clinically relevant maternal and/or fetal outcome problems related to BMIs >35 kg/m2. Additional studies are however needed to confirm our results.

RESUMO

Spina bifida affects spinal cord and cerebral development, leading to motor and cognitive delay. We investigated whether there are associations between thalamocortical connectivity topography, neurological function, and developmental outcomes in open spina bifida. Diffusion tensor MRI was used to assess thalamocortical connectivity in 44 newborns with open spina bifida who underwent prenatal surgical repair. We quantified the volume of clusters formed based on the strongest probabilistic connectivity to the frontal, parietal, and temporal cortex. Developmental outcomes were assessed using the Bayley III Scales, while the functional level of the lesion was assessed by neurological examination at 2 years of age. Higher functional level was associated with smaller thalamo-parietal, while lower functional level was associated with smaller thalamo-temporal connectivity clusters (Bonferroni-corrected P < 0.05). Lower functional levels were associated with weaker thalamic temporal connectivity, particularly in the ventrolateral and ventral anterior nuclei. No associations were found between thalamocortical connectivity and developmental outcomes. Our findings suggest that altered thalamocortical circuitry development in open spina bifida may contribute to impaired lower extremity function, impacting motor function and independent ambulation. We hypothesize that the neurologic function might not merely be caused by the spinal cord lesion, but further impacted by the disruption of cerebral neuronal circuitry.

RESUMO

PURPOSE: This study aimed to describe outcomes of motor function with a special focus on ambulation ability at 36 months among children with open prenatal repair of spina bifida aperta (SB). METHODS: A prospective cohort study was conducted including 87 patients with open prenatal repair of SB at the investigating center born between 2010 and 2018. Anatomic lesion level and motor function level in the neonatal period, as well as motor function level, ambulation status, and use of orthotics and assistive devices at 36 months were assessed. RESULTS: At 36 months, ambulation was assessed in 86 children; of those, 86% (n = 74) were ambulating. Independent of ambulation, orthotics were worn in 81.6% (71/87) and assistive devices in 47.1% (41/87). Children with a lower lumbar or sacral motor function level were the first to reach independent ambulation and were more likely to ambulate at 36 months than children with higher motor function levels (p = < .001). The anatomic lesion level determined on the neonatal MRI correlated with ambulation status at 36 months (p = < 0.001). CONCLUSION: At 36 months, most children with open prenatal repair for SB showed favourable ambulation status. However, most still used assistive devices or orthotics. Anatomic lesion level on neonatal MRI, motor function level during the neonatal period, and motor function level at 36 months were associated with ambulation status at 36 months.

RESUMO

INTRODUCTION: We hypothesize that after publication of the quintessence of the MOMS trial, eligibility criteria for prenatal spina bifida (SB) repair may be modified if a tenable argumentation underlies this decision. METHODS: Our first 154 fetal surgery patients were analyzed with particular focus on how many, which, and why the original eligibility criteria, set forth by the MOMS Trial Protocol, were disobeyed, and what the eventually detectable, negative and positive impacts of these deviations on outcomes were. RESULTS: A total of 152 patients (2 missing consent) were included (100%). In 69 patients (45.4%), a total of 89 eligibility criteria were disobeyed. In 54 (35.6%) cases, the following maternal criteria were concerned: gestational age at operation of >25+6 weeks in 17 (11.2%), uterine pathologies in 13 (8.6%) women, preoperative BMI ≥35 kg/m2 in 12 (7.9%), previous hysterotomy in 7 (4.6%), previous prematurity in 3 (2%), HIV/hepatitis B in 2 (1.3%), psychosocial issues in 2 (1.3%), and placenta praevia in 1 (0.7%). In 32 (21.1%) cases, fetal criteria were disobeyed 34 times: Fetal anomaly unrelated to SB in 19 (12.5%), no/minimal evidence of hindbrain herniation in 13 (8.6%), and severe kyphosis in 2 (1.3%). We could not identify cases where non-observation of criteria led to clear-cut maternal and/or fetal disadvantages. CONCLUSION: This study shows that MOMS trial eligibility criteria for prenatal SB repair should be modified or even abandoned with adequate medical and ethical argumentation, and with written parental informed consent after non-directive, full disclosure counseling. This clear-cut change of paradigm is a necessity as it leads toward personalized medicine, allowing more fetuses to benefit from fetal surgery than would have benefitted with the former, published, MOMS criteria in place.

RESUMO

BACKGROUND: Increased pulse wave reflection in the fetal arterial system, illustrated by a second systolic peak (M-sign) in middle cerebral artery (MCA) Doppler waveforms, allows interpretation of fetal systemic vasoconstriction. Little is known about fetal vascular regulation during fetal spina bifida (fSB) repair. Therefore, the aim of this study was to analyze MCA-Doppler waveform changes before, during, and after fSB repair. PATIENTS AND METHODS: 31 pregnant women who underwent fSB repair were included. Fetal MCA-Doppler waveforms were prospectively analyzed before, during and after fSB repair, and categorized as follows: normal systolic downslope, systolic shoulder, second systolic peak (M-sign), and concave systolic downslope. These MCA waveforms were related to maternal and fetal characteristics, to anesthetic medication, and to umbilical artery (UA) waveforms. RESULTS: Before fSB repair, all fetuses repeatedly presented M-signs. After initiation of desflurane for general anesthesia, systolic shoulder and the M-sign vanished in 24/31 (78%) fetuses and 19/31 (61%) showed transient UA ARED flow. A significant association between these two Doppler findings was found (p=0.007). After fSB repair, signs of increased pulse wave reflection reappeared but resolved over time (23 days ± 20, SD) in all fetuses. CONCLUSION: Both fSB and intrauterine repair influence fetal vascular regulation. This phenomenon can be illustrated by MCA-Doppler waveforms. While anesthetic agents transiently eliminated M-signs and often provoked a UA ARED flow, fSB repair finally led to normalization of MCA-Doppler waveforms indicating return to normal fetal vascular regulation.

RESUMO

INTRODUCTION: Vaginal dysbiosis affects pregnancy outcomes, however, the relevance of abnormal findings on pre/post-surgical vaginal culture in women undergoing fetal spina bifida (fSB) repair is unknown. OBJECTIVES: To describe the incidence of normal and abnormal pre- and post-surgical vaginal microorganisms in fSB patients and to investigate potential associations between the type of vaginal flora and the occurrence of preterm prelabour rupture of membranes (PPROM) and preterm birth (PTB). METHODS: 99 women undergoing fSB repair were eligible (2010-2019). Pre-surgical vaginal culture was routinely taken before surgery. Post-surgical cultures were taken on indication. Vaginal flora was categorized into four categories: healthy vaginal flora (HVF), bacterial vaginosis (BV), desquamative inflammatory vaginitis (DIV), and yeast infection. RESULTS: The incidence of HVF, BV, DIV, or yeast infections was not statistically different between the pre- and postoperative patients. Furthermore, an abnormal pre/post-surgical vaginal flora was not associated with PPROM (OR 1.57 (0.74-3.32), p = 0.213)/OR 1.26 (0.62-2.55), p = 0.515), or with PTB (OR 1.19 (0.82-1.73), p = 0.315)/(OR 0.86 (0.60-1.24), p = 0.425). CONCLUSIONS: Abnormal vaginal microbiome was not associated with PPROM and PTB when appropriate treatment was performed.

RESUMO

INTRODUCTION: Fetal spina bifida (SB) repair is a distinct therapeutic option in selected cases. Since this procedure may not only be associated with short-term obstetrical complications, the aim of this study was to assess the outcomes of subsequent pregnancies after open fetal SB repair. METHODS: 138 patients having had open fetal SB repair at our center received a questionnaire regarding the occurrence, course, and outcome of subsequent pregnancies. Additionally, medical records were reviewed. All subsequent pregnancies with complete outcome data that progressed beyond 20 gestational weeks (GW) were included for further analysis. RESULTS: 70% of all women answered the questionnaire. Out of this cohort, 35 subsequent pregnancies were reported in 29% of women. The rate of early pregnancy loss including elective terminations was 14%. All 29 pregnancies processing >20 GW ended in live births without preterm births <34th GW. Mean gestational age at delivery was 37.3 ± 1.4 GW. Uterine rupture occurred in two cases (7%) and uterine thinning/dehiscence was present in six cases (21%). No maternal transfusions were required. CONCLUSION: When counseling women undergoing open fetal SB repair, one should consider possible risks for subsequent pregnancies, especially the one of uterine dehiscence and rupture that is similar compared to numbers reported after classical cesarean deliveries.

RESUMO

INTRODUCTION: In select cases, in utero surgery for myelomeningocele (MMC) leads to better outcomes than postnatal repair. However, maternal HIV infection constitutes a formal exclusion criterion due to the potential of vertical HIV transmission. Encouraged by a previous case of a successful fetal spina bifida repair in a Hepatitis Bs antigen-positive woman, a plan was devised allowing for fetal surgery. CASE REPORT: In utero MMC repair was performed although the mother was HIV-infected. To minimize the risk of in utero HIV transmission, the mother was treated by highly active antiretroviral therapy throughout gestation as well as intravenous zi-dovudine administration during maternal-fetal surgery. The mother tolerated all procedures very well without any sequelae. The currently 20 month-old toddler is HIV negative and has significantly benefitted from fetal surgery. DISCUSSION/CONCLUSION: This case shows that maternal HIV is not a priori a diagnosis that excludes fetal surgery. Rather, it might be a surrogate for moving towards personalized medicine and away from applying too rigorous exclusion criteria in the selection of candidates for maternal-fetal surgery.

RESUMO

PURPOSE: The goal of this study was to assess the accuracy of prenatal anatomical level determination by ultrasound (US) and magnetic resonance imaging (MRI) by analyzing the congruence with the "true" anatomical level identified by postnatal MRI. PATIENTS AND METHODS: The first 60 patients undergoing fetal myelomeningocele surgery at The Zurich Center for Fetal Diangosis and Therapy were included in this study. Anatomical levels (i. e., first dysraphic vertebra) determined by prenatal US and MRI were compared to postnatal MRI. The level of agreement between the imaging modalities was evaluated with a Cohen's kappa test. Results > 0.6 were interpreted as good agreement, > 0.8 as excellent. RESULTS: The exact congruence between prenatal US and MRI compared to postnatal MRI was 33 % and 48 %, respectively, for an accuracy within one level difference of 80 % and 90 %, and within two levels difference of 95 % and 98 %, respectively. The level of agreement of prenatal US and MRI compared to postnatal MRI was 0.62 and 0.79, respectively. Most of the prenatally incorrectly assigned levels were assigned too high (worse) than the "true" level (US 88 % vs. MRI 65 %). CONCLUSION: Reliable exact prenatal level determination by US and MRI is not possible. However, the prenatal determination of the anatomical level of the lesion is good within one level margin of error. Prenatal US as well as MRI demonstrate a systematic error towards higher levels. The above considerations must be integrated into prenatal counselling.

RESUMO

INTRODUCTION: Surgical treatment of esophageal atresia (EA) has markedly improved, allowing the focus to shift from short-term complications and mortality to long-term complications and quality of life. Health-related quality of life (HRQoL) is variable and reported to range from reduced to unimpaired in patients with repaired EA. We assessed the HRQoL, determined the prevalence of long-term complications and their possible impact on the HRQoL in patients who had correction of EA in Switzerland. Further, we also investigated in the general well-being of their parents. MATERIALS AND METHODS: Patients with EA repair in Switzerland between 1985 and 2011 were enrolled. Long-term complications were assessed by enquiring disease-related symptoms, standardized clinical examinations, and analysis of radiographs. HRQoL was inquired using different validated questionnaires (KIDSCREEN-27, World Health Organization [WHO]-5, and Gastrointestinal Quality of Life Index [GIQLI]). Patients were grouped according to their age. In underage patients, general well-being of the parents was assessed using the WHO-5 questionnaire. RESULTS: Thirty patients were included with a mean age of 11.3 ± 5.7 years. Long-term complications were present in 63% of all patients. HRQoL in underage patients was comparable to the provided reference values and rated as good, while adult patients reported a reduced HRQoL. The presence of gastroesophageal reflux disease symptoms was associated with reduced HRQoL in underage patients. Parents of underage patients stated a good general well-being. CONCLUSION: Long-term complications among patients with repair of EA in Switzerland are common. HRQoL in underage patients is good and general well-being of their parents is unimpaired. Adult patients reported a reduced HRQoL, consistent with other reports. As long-term complications may manifest only later in life, a structured follow-up of patients with an EA repair during childhood and adolescence is needed.

RESUMO

Background: A remaining risk of fetal spina bifida (fSB) repair is preterm delivery. This study assessed the value of preoperative cervical length (CL), CL dynamics (∆CL) and fetal fibronectin (fFN) tests to predict obstetric complications and length of stay (LOS) around fSB repair. Methods: 134 patients were included in this study. All patients had CL measurement and fFN testing before fSB repair. ∆CL within the first 14 days after intervention and until discharge after fSB repair were compared in groups (∆CL ≥ 10 mm/<10 mm; ≥20 mm/<20 mm). CL before surgery, ∆CL's, and positive fFN tests were correlated to obstetric complications and LOS. Results: Mean CL before surgery was 41 ± 7 mm. Mean GA at birth was 35.4 ± 2.2 weeks. In the group of ∆CL ≥ 10 mm within the first 14 days after intervention, LOS was significantly longer (p = 0.02). ∆CL ≥ 10 mm until discharge after fSB was associated with a significantly higher rate of GA at birth <34 weeks (p = 0.03). The 3 positive fFN tests before fSB repair showed no correlation with GA at birth. Conclusion: Perioperative ∆CL influences LOS after fetal surgery. ∆CL ≥ 10 mm until discharge after fSB repair has a 3-times higher rate of preterm delivery before 34 weeks. Preoperative fFN testing showed no predictive value for preterm birth after fSB repair and was stopped.

RESUMO

INTRODUCTION: This retrospective study investigates brain malformations and their impact on neurodevelopmental outcome in children after prenatal surgery for spina bifida (SB). METHODS: Sixty-one patients were included. On neonatal MRI, SB-associated brain malformations were assessed. Ventricular size, ventriculo-peritoneal shunt (VPS), and endoscopic third ventriculostomy (ETV) were also documented. Neurodevelopment was assessed with the Bayley-III and correlated with brain malformations, ventricular size, and VPS/ETV placement. RESULTS: Chiari II malformation was detected in all patients. Corpus callosum (CC) abnormality was noted in 40%, heterotopies in 35%, and cerebellar parenchymal defects in 11%. 96% had ventriculomegaly; in 46%, VPS/ETV was performed. Cognitive and language testing yielded results in the low-average range (Bayley-III: Cognitive Composite Score 93.6, Language Composite Score 89.7), motor testing was below average (Motor Composite Score 77.4). CC abnormalities, heterotopies, and cerebellar defects were not associated with poorer Bayley-III scores, whereas patients with severe ventriculomegaly performed poorer in all subtests, significantly so for the language composite score. Patients requiring intervention for hydrocephalus had significantly lower scores in motor testing. DISCUSSION/CONCLUSION: Additional brain malformations in open SB do not seem to have an impact on cognitive function at 2 years of age. Severe ventriculomegaly is a risk factor for poorer cognitive outcome; hydrocephalus surgery adds an additional risk for delayed motor function.

RESUMO

AIM: To investigate neurodevelopmental outcome of children with open prenatal spina bifida aperta (SBA) repair. METHOD: Prenatal SBA repair was performed in 130 fetuses at the Zurich Center between 2010 and 2019. Seventy-seven children underwent 1 year assessment with the Griffiths Mental Developmental Scales (Griffiths) and 65 with the Bayley Scales of Infant and Toddler Development, Third Edition (Bayley-III) at 2 years. Anatomical and functional level and ambulation status were assessed. Descriptive statistics and multiple linear regression analyses for risk factors were performed. RESULTS: The Bayley-III cognition composite score in children with prenatal SBA repair was within normal limits but lower compared to population norms (mean=95.15, SD=14.683 vs norm=100, SD=15, p=0.01). Fine motor development (mean=9.58, SD=2.744, p=0.227) was typical while gross motor development was lower than the norm (mean=3.02, SD=2.758 vs norm=10, SD=3, p<0.001). Griffiths developmental quotient subscales correlated significantly with corresponding Bayley-III scores (all p<0.001, r=0.519-0.594). At 2 years, 50.8% could walk. INTERPRETATION: Children with non-trial open prenatal SBA repair show favourable cognitive outcome in the low-average range at 1 and 2 years of age. While gross motor function remained delayed, fine motor function was age appropriate. The correlation between Griffiths and Bayley-III allows a prediction about neurodevelopmental outcome at the age of 1 year. What this paper adds Children with non-trial open prenatal spina bifida repair show favourable cognitive outcome. Gross motor function remains impaired, while fine motor function is age appropriate. At 2 years of age, 50.8% of children were walking. Neurodevelopmental testing correlated between 1 (Griffiths Mental Developmental Scales) and 2 (Bayley Scales of Infant and Toddler Development, Third Edition) years.

RESUMO

Magnetic resonance imaging (MRI) has become an essential diagnostic modality for congenital disorders of the central nervous system. Recent advancements have transformed foetal MRI into a clinically feasible tool, and in an effort to find predictors of clinical outcomes in spinal dysraphism, foetal MRI began to unveil its potential. The purpose of our review is to introduce MRI techniques to experts with diverse backgrounds, who are involved in the management of spina bifida. We introduce advanced foetal MRI postprocessing potentially improving the diagnostic work-up. Importantly, we discuss how postprocessing can lead to a more efficient utilisation of foetal or neonatal MRI data to depict relevant anatomical characteristics. We provide a critical perspective on how structural, diffusion and metabolic MRI are utilised in an endeavour to shed light on the correlates of impaired development. We found that the literature is consistent about the value of MRI in providing morphological cues about hydrocephalus development, hindbrain herniation or outcomes related to shunting and motor functioning. MRI techniques, such as foetal diffusion MRI or diffusion tractography, are still far from clinical use; however, postnatal studies using these methods revealed findings that may reflect early neural correlates of upstream neuronal damage in spinal dysraphism.

RESUMO

PURPOSE: Over the past 10 years, over 150 fetal spina bifida surgeries were performed at the Zurich Center for Fetal Diagnosis and Therapy. This study looks at surrogates for success and failure of this approach. METHODS: We focused on key outcome parameters including hydrocephalus shunt rate at one year, bladder control at 4, independent ambulation at 3 years, and maternal, fetal, and neonatal complications. RESULTS: From the first 150 patients undergoing fetal surgery for spina bifida, 148 (98.7%) were included in the study. Maternal-fetal surgery was uneventful in 143/148 (97%) cases. Intraoperative problems included resuscitation in 4/148 fetuses (2.7%). 1/148 fetuses (0.7%) died on postoperative day 4. Maternal complications included chorioamniotic membrane separation in 22/148 (15%), lung embolism in 3/148 (2.1%), chorioamnionitis in 2/148 (1.4%), AV-block III and uterine rupture in 1/148 each (0.7%). 1/148 (0.7%) newborn death was recorded. Hindbrain herniation was identified preoperatively in 132/148 (90%) fetuses and resolved completely in 119/132 (90%). At one year, 39/106 (37%) children had required a CSF diversion. At 4 years, 4/34 patients (12%) had normal bladder control. At 3 years, 48/57 (84%) walked independently. CONCLUSION: A majority of patients benefitted from prenatal intervention, in that the shunt rate was lower and the rates of continent and walking patients were higher than reported with postnatal care.

RESUMO

PURPOSE: The aim was to describe the sonographic follow-up of hindbrain herniation (HH), the banana and lemon sign after fetal myelomeningocele (fMMC) repair, and the time of disappearance of these signs after the intervention, and to investigate any predictive value for the necessity of shunting during the infant's first year of life. Additionally, the sonographic evolution of the transcerebellar diameter (TCD) before and after fetal intervention was assessed. PATIENTS AND METHODS: The first 50 patients that underwent fMMC repair at Zurich Center for Fetal Diagnosis and Therapy (www.swissfetus.ch) were included in this study. Sonographic scans performed weekly after fMMC repair focusing on HH and banana and lemon signs were analyzed and compared between the shunted and the non-shunted group. ROC curves were generated for the time intervals of resolution of the signs in order to show their predictive accuracy for the need for shunting until 1 year of age. RESULTS: HH resolved in 48 fetuses (96 %) before delivery. The sonographic disappearance of HH within the first two weeks after fMMC repair was associated with a significantly lower incidence of shunt placement (OR 0.19; 95 % CI 0.4-0.9) during the first year of life (p = 0.03). All fetuses with persistent HH before delivery received a shunt. TCD growth was observed in all fetuses. CONCLUSION: The reversibility of HH within two weeks after fMMC repair is associated with an 80 % lower incidence of shunt placement during the infant's first year of life. Moreover, it allows the cerebellum to grow and to normalize its configuration.
