CONTEXT: Umbilical cord thrombosis is related to greater fetal and perinatal morbidity and mortality. It is usually associated with umbilical cord abnormalities that lead to mechanical compression with consequent vascular ectasia. Its correct diagnosis and clinical management remains a challenge that has not yet been resolved. CASE REPORT: This study reports a case of umbilical artery thrombosis that occurred in the second half of a pregnancy. The umbilical cord was long, thin and overly twisted and the fetus presented severe intrauterine growth restriction. The clinical and histopathological findings from this case are described. CONCLUSIONS: This case report emphasizes the difficulty in diagnosing and clinically managing abnormalities of intrauterine life with a high chance of perinatal complications. RESUMO CONTEXTO:A trombose do cordão umbilical está relacionada com o aumento da morbimortalidade fetal e perinatal. É geralmente associada a alterações do cordão umbilical que levam à compressão mecânica com consequente ectasia vascular. Seu correto diagnóstico e manejo clínico é um desafio que não está ainda bem esclarecido. RELATO DE CASO: Neste relato se descreve caso de trombose da artéria umbilical de ocorrência na segunda metade da gravidez associada a cordão umbilical longo, fino, excessivamente retorcido, associado a feto com restrição de crescimento intrauterino grave. São descritos seus achados clínicos e histopatoló-gicos correlacionados. CONCLUSÃO: Este relato de caso reforça a dificuldade diagnóstica e de manejo clínico em alteração da vida intrauterina com grande possibilidade de complicações perinatais.

We report the long-term outcomes of a case of prenatal gastroschisis repair using a fully percutaneous fetoscopic approach with partial carbon dioxide insufflation. Surgery was performed as an experimental procedure before the scheduled elective birth. The fetal intestines were successfully returned to the abdominal cavity without any fetal or maternal complications. Ultrasonography performed 24 hours later revealed bowel peristalsis and no signs of fetal distress. After 48 hours, partial extrusion of the small bowel was observed, and the fetus was delivered. Gastroschisis repair was immediately performed upon delivery using the EXIT-like procedure as per our institutional protocol. The newborn did not require assisted mechanical ventilation, was discharged at 14 days of age and was then exclusively breastfed. At 3-year follow-up, the patient had no associated gastroschisis-related complications. This is the first case of prenatal repair of gastroschisis, which provides baseline knowledge for future researchers on the potential hurdles and management of prenatal repair.
