Resumo

Introdução: A morfometria vascular desempenha um papel fundamental no diagnóstico de patologias congênitas e no suporte ao manejo clínico. Embora os diâmetros dos grandes vasos em adultos sejam bem estabelecidos, com influências de fatores como idade e sexo, ainda existe uma lacuna na literatura em relação ao seu desenvolvimento em fetos. Em particular, a relação entre os diâmetros da aorta ascendente (AA), tronco pulmonar (TP) e tronco braquiocefálico (TBC) com a idade gestacional e o sexo, bem como o início do dimorfismo sexual ao longo do desenvolvimento, permanece inexplorada. Objetivo: Investigar a correlação entre os diâmetros da AA, TP e TBC com a idade gestacional e o sexo em fetos humanos. Metodologia: Trinta e cinco cadáveres fetais (18 masculinos, 17 femininos), coletados entre 2012 e 2020 no Laboratório de Anatomia Humana da UFS, foram analisados após aprovação ética e exclusão de malformações cardiovasculares. A idade gestacional foi determinada utilizando o método do comprimento hálux-calcâneo. Os diâmetros externos da AA, TP e TBC foram medidos com um paquímetro digital. Os dados foram analisados utilizando o coeficiente de correlação de Spearman para avaliar associações com a idade gestacional e o teste t de Student para comparar diferenças entre os sexos. Resultados: Foram encontradas fortes correlações positivas entre a idade gestacional e os diâmetros da AA (ρ = 0,710), TP (ρ = 0,701) e TBC (ρ = 0,828) (p < 0,001 para todos), confirmando um crescimento consistente ao longo do desenvolvimento fetal. Nenhuma diferença significativa foi encontrada entre sexos masculino e feminino (p > 0,05). Conclusão: Este estudo fornece dados normativos fetais para a AA, TP e TBC, demonstrando que os diâmetros dos vasos aumentam proporcionalmente com a idade gestacional. A ausência de dimorfismo sexual no período fetal sugere que fatores hormonais e ambientais pós-natais podem contribuir para as diferenças de tamanho vascular observadas mais tarde na vida. Essas descobertas fornecem valores de referência clinicamente relevantes para o diagnóstico pré-natal de anormalidades vasculares. Além disso, aprimoram a compreensão do desenvolvimento vascular.
