RESUMENConsideramos marcadores de cardiopatías congénitas al grupo de lesiones que, pudiendo ser variantes normales, se asocian a defectos cardíacos. En esta primera publicación destacamos la importancia del diagnóstico de la interrupción de la vena cava inferior (VCI) y su continuación por el sistema azygos, como un marcador de isomerismo auricular y poliesplenia. En toda nuestra serie de cardiopatías congénitas (Cc), hemos diagnosticado 5 anomalías de la VCI, 4 de ellas correspondieron a interrupciones sin Cc asociadas. Reportamos los hallazgos in utero y el seguimiento postnatal de estos casos, la técnica más apropiada para su pesquisa y su asociación a Cc.
PALABRAS CLAVES: Diagnóstico prenatal, cardiopatías congénitas SUMMARYWe consider markers of congenital hear disease a group of anomalies which could be a normal variant in general population but might be associated to structural defects of the fetal heart. One of those marks is the interruption of the inferior vena cava with azygos vein continuation. Among 5 abnormalities of the inferior vena cava diagnosed in our series, we found 4 interruption of the IVC. We discuss in utero abnormalities and follow-up. We propose the technique to screen a group of congenital heart disease with the vascular arrangements in the fetal abdomen.
Ten cases of prenatal ultrasound diagnosis of urological malformations and their posterior surgical managment are presented. Prenatal ultrasound, was very accurate for the diagnosis of obstruction, but not in the identification of its actual cause. Survival results in the treatment of ureteropelvic junction obstruction (6 kidneys) were good and nephrostomy was not necessary. One kidney with preoperative exclusion got better after pyeloplasty. Good results were also obtained in other procedures; nephroureterectomy and section of the bridge in a patient with horseshoe kidney, one case of inferior heminephrectomy and another of superior heminephrectomy. Recurrent prolapse in a child with temporary Blocksom vesicostomy needed further surgery. No operation was required in a case of bilateral hydronephiosis caused by a distal rectal pouch in a patient with imperforate anus. (
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.
