Resumen
Introducción: los defectos del tubo neural son un grupo heterogéneo de alteraciones del sistema nervioso central, de origen multifactorial, principalmente ocasionados por una falla en los mecanismos de cierre del tubo neural, la cual involucra: piel, músculos paravertebrales, tejido conectivo, hueso y médula espinal. La craneorraquisquisis es la variante más grave y rara de los defectos del tubo neural.
Caso clínico: Mujer de 36 años con un embarazo de 25.3 semanas, corroborado por ultrasonido del segundo trimestre, con el antecedente de un embarazo previo con anencefalia y mal control prenatal en el embarazo actual. Se le realizó un ultrasonido que diagnosticó craneorraquisquisis, por lo que se procedió a finalizar el embarazo por inducción de trabajo de aborto con prostaglandinas.
Conclusiones: la craneorraquisquisis es un defecto raro del tubo neural que debe diagnosticarse tempranamente por ser una patología incompatible con la vida.
Abstract
Background: Neural tube defects are a heterogeneous group of alterations of the central nervous system with multifactorial origin, mainly caused by a failure in the mechanisms of closure of the neural tube which involves skin, paravertebral muscles, connective tissue, bone and spinal cord.
Clinical case: 36-year-old woman with a pregnancy of 25.3 weeks, corroborated by second trimester ultrasound. She had a previous pregnancy with anencephaly and a poor prenatal care in the actual pregnancy. An obstetric ultrasound was performed with the diagnosis of craniorachischisis, which is why the delivery was performed by vaginal birth with labor induction with prostaglandins.
Conclusions: The craniorachischisis is a rare defect of the neural tube that must be diagnosed early because it is a pathology incompatible with life.
