RESUMO

BACKGROUND: Fetal aortic valvuloplasty (FAV) is proposed to prevent hypoplastic left heart syndrome due to fetal critical aortic stenosis. OBJECTIVE: to report our experience on FAV as the first step in a complex therapeutic strategy. METHOD: Series of patients with FAV over an 18-year period. RESULTS: 27 FAVs were performed in 26 fetuses, with technical success in 82% (22/27) and periprocedural fetal demise in 22% (6/27), decreasing to 15% in the second half-cohort. Loss to follow-up was due to birth or postnatal therapy in other centers (5) and termination of pregnancy (1), A normal-sized LV at birth was observed in 46% (6/13), 4 neonates underwent aortic valvuloplasty and 2 cardiac surgeries, with 5/6 achieving biventricular circulation at 28 days, and 3 transplant-free survival at mid-term follow-up. The 7/13 born with a borderline LV underwent LV rehabilitation strategy, with survival at 28 days in 4/7 and at mid-term in 3: one with biventricular circulation, one with a ventricle-and-a-half repair, and one lost to follow-up. CONCLUSION: FAV was feasible in most cases, with no maternal complications, and biventricular circulation at 28 days in ∼40% of survivors. After FAV, a diverse range of postnatal cardiac interventions are performed, reflecting the challenging innovation in current cardiovascular therapy.

RESUMO

PURPOSE: We aim to compare the perinatal outcomes of two consecutive management strategies for fetal growth restriction (FGR), with or without the inclusion of additional Doppler parameters. METHODS: A quasi-experimental before/after study was conducted in which we compared a composite perinatal outcome, prematurity rate, and neonatal complications between two management strategies in small fetuses. In the strategy 1 (S1), the management was based on fetal biometry and umbilical artery Doppler. The second strategy (S2) added the assessment of uterine and middle cerebral artery Doppler. We also compared outcomes between strategies according to early (≤ 32 weeks) and late (> 32 weeks) diagnosis subgroups. RESULTS: We included 396 patients, 163 in S1 and 233 in S2. There were no significant differences in the perinatal composite outcome (p 0.98), prematurity (p 0.19), or in the subgroup analysis. We found a significant reduction in respiratory distress syndrome (RDS) rate with S2 both globally (OR 0.50, p 0.02), and in the early diagnosis subgroup (OR 0.45, p 0.01). In addition, we observed a significant reduction in the incidence of sepsis with S2 both globally (OR 0.30, p 0.04) and in the early diagnosis subgroup (OR 0.25, p 0.02). We did not observe significant differences in necrotizing enterocolitis (p 0.41) and intraventricular hemorrhage (p 1.00). CONCLUSION: The expanded strategy for the management of FGR did not show significant differences in the primary composite outcome or prematurity. However, it was associated with a lower incidence of RDS and neonatal sepsis.

RESUMO

INTRODUCTION: Hysterectomy is the standard of care in placenta accreta spectrum (PAS). To reduce the risks of obstetric hemorrhage during surgery, endovascular interventions have been proposed. Our aim is to evaluate the feasibility and safety of the overall non-conservative management of PAS in the hybrid operating room (OR) to replace the classic two-step procedure (catheterization in the interventional radiology suite and transfer to conventional OR). MATERIALS AND METHODS: This is a retrospective study of series of patients with histopathologic confirmation of PAS treated in the hybrid OR at the same university hospital. We used for comparison our historical cohort managed with the standard two-step procedure. RESULTS: We included 110 patients, 80 in the conventional OR and 30 in the hybrid OR. There were no cases of major complications attributable to the endovascular procedures. In the two-step procedure, there were 10 (12.5%) intra-arterial catheter displacements that required repositioning in the conventional OR under mobile C-arm fluoroscopy and no cases in the hybrid OR (p = 0.04). The mean operative time was 380 + 42 min in the conventional OR and 296 + 66 min in the hybrid OR (p = .00001). There were no differences in the gestational age at delivery, postoperative length of stay, or large-volume blood transfusion. There were no maternal deaths. CONCLUSIONS: The overall non-conservative management of PAS in the hybrid OR has shown to be feasible and safe in our series, offering potential advantages to replace the classic two-step procedure. More studies are needed to evaluate whether this strategy is cost-effective and whether it may improve maternal and perinatal outcomes.

RESUMO

The administration of magnesium sulphate to mothers at risk for preterm birth for fetal neuroprotection has demonstrated to reduce the risk of cerebral palsy and gross motor dysfunction by 30-40%. Although there is controversy regarding the regimen of administration of magnesium sulphate, the gestational age limit, the extent of its potential benefit or even if it provides any benefit, current evidence is enough to support the use of magnesium sulphate in women at imminent risk for preterm delivery before 32 weeks of gestation. The objective of this study is to describe available evidence and current recommendations regarding neuroprotection with magnesium sulphate.

RESUMO

Fetal therapy may be needed in certain clinical settings with the primary indication to improve perinatal or long-term outcomes for the fetus or the newborn. It can be classified in pharmacotherapy or non-invasive, and invasive therapy. The first one involves the administration of drugs to the mother that cross the placenta and get to the fetus, a non-invasive approach. On the other hand, invasive therapy involves the use of needles, fetoscopic treatments or open fetal surgery. This review provides an update of non-invasive and invasive fetal therapy.
