RESUMO:A cirurgia fetal é, hoje, uma realidade em grandes centros especializados na área da medicina fetal. Surgiu por volta da década de 1960, inicialmente atrelada à necessidade de melhor conhecer e entender as patologias fetais, e teve desenvolvimento exponencial impulsionado pelo aprimoramento das técnicas diagnósticas pré-natais. Foi aos poucos se consolidando e tornando-se o tratamento de escolha para algumas patologias específicas, mudando definitivamente o curso dessas doenças. Nesse estudo, encontra-se um breve histórico das cirurgias fetais mais comumente realizadas em todo o mundo, como elas surgiram e como foram evoluindo com o passar do tempo, os principais estudos que as validaram e a técnica cirúrgica mais amplamente utilizada em cada caso. Entre as principais cirurgias, são citadas a fotocoagulação a laser de anastomoses placentárias na síndrome de transfusão feto-fetal, a correção intrauterina a céu aberto da mielomeningocele fetal e a oclusão endotraqueal fetal por balão nos casos de hérnia diafragmática congênita. Também são abordados cirurgias e procedimentos cujos benefícios são menos evidentes e os resultados ainda um tanto controversos, como as intervenções urinárias nos casos de obstrução ao trato urinário inferior, procedimentos cardíacos em casos de estenose aórtica crítica, derivações tóracoamnióticas para tratamento de derrames pleurais compressivos, além de ressecções intrauterinas de teratomas sacrococcígeos e de massas pulmonares. Também é feita uma avaliação a respeito do futuro da cirurgia fetal.Descritores: Feto/cirurgia; Fetoscopia. ABSTRACT:Fetal surgery is now a reality in large centers that specialize in the field of fetal medicine. Fetal surgery emerged in the 1960s, primarily from the need to better identify and understand fetal pathologies, and its exponential development was driven by improvements in prenatal diagnostic techniques. Fetal surgery gradually became the main treatment for specific fetal pathologies, changing the course of these diseases. This study summarizes the history of the fetal surgeries that are most commonly performed worldwide, how they started and how they evolved over time, the main validation trials and the most widely used surgical technique in each case. The main surgeries include laser photocoagulation of placental anastomoses in twin-to-twin transfusion syndrome, in utero repair of fetal myelomeningocele and fetal endotracheal occlusion in cases of congenital diaphragmatic hernia. Other surgeries and procedures, whose benefits are less clear and whose results are still somewhat controversial, such as urinary interventions in cases of lower urinary tract obstruction, cardiac procedures in cases of critical aortic stenosis, thoracoamniotic shunts for the treatment of massive pleural effusions and intrauterine resection of sacrococcygeal teratomas and pulmonary masses, are also cited. The future of fetal surgery is also assessed.
Objectives Open spina bifida (OSB) is the most common neural tube defect. Prenatal repair reduces the need for ventriculoperitoneal shunting (VPS) due to hydrocephalus from 80–90% to 40–50%. We aimed to determine which variables work as risk factors for VPS at 12 months of age in our population. Methods Thirty-nine patients underwent prenatal repair of OSB by mini-hysterotomy. The main outcome was occurrence of VPS in the first 12 months of life. Logistic regression was used to estimate the odds ratios (OR) between prenatal variables and the need for shunting. Results VPS at 12 months occurred in 34.2% of the children. Larger ventricle size before surgery (62.5% ≥15 mm; 46.2% between 12 and 15 mm; 11.8% <12 mm; p=0.008), higher lesion level (80% >L2, vs. 17.9% ≤L3; p=0.002; OR, 18.4 [2.96–114.30]), and later gestational age at surgery (25.25 ± 1.18 vs. 24.37 ± 1.06 weeks; p=0.036; OR, 2.23 [1.05–4.74]) were related to increased need for shunting. In the multivariate analysis, larger ventricle size before surgery (≥15 mm vs. <12 mm; p=0.046; OR, 1.35 [1.01–1.82]) and higher lesion level (>L2 vs. ≤L3; p=0.004; OR, 39.52 [3.25–480.69]) were risk factors for shunting. Conclusions Larger ventricle size before surgery (≥15 mm) and higher lesion level (>L2) are independent risk factors for VPS at 12 months of age in fetuses undergoing prenatal repair of OSB by mini-hysterotomy in the studied population.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
