Se le asocia frecuentemente con gemelaridad, malformaciones y crecimiento intrauterino retardado, y constituye un factor de riesgo de prematuridad, muerte fetal y neonatal.  Objetivos:  Determinar la prevalencia de la arteria umbilical única en gestantes, y la asociación de esta entidad con otras malformaciones y el bajo peso al nacer.  Materiales y métodos:  Estudio descriptivo retrospectivo, con datos obtenidos de las historias clínicas y del modelo de seguimiento lineal existente en las consultas de genética comunitaria del municipio Matanzas, de enero de 2015 a diciembre de 2019.  Resultados:  La prevalencia de la arteria umbilical única fue del 0,3 %. Las malformaciones más frecuentes fueron las renales; el 27,7 % de los nacimientos fueron pretérmino y el 33,3 % de los nacidos fue con un peso inferior a 2500 g.  Conclusiones:  La arteria umbilical única constituye un marcador para otras malformaciones. Cuando coexisten ambas existe riesgo de prematuridad y bajo peso al nacer. Se recomienda realizar examen clínico posnatal a todo recién nacido con arteria umbilical única, pesquisando defectos renales y cardíacos.]]></p></abstract>

It is frequently associated with twinning, malformations and delayed intrauterine growth, and is a risk factor of prematurity, fetal and neonatal death.  Objective:  To determine the prevalence of single umbilical artery in pregnant women and the association of this entity with other malformations and low birth weight.  Materials and methods: Retrospective descriptive study, with data obtained from medical records and the linear follow-up model existing in the community genetic clinics of the municipality of Matanzas, from January 2015 to December 2019.  Results:  The prevalence of the single umbilical artery was 0.3%. The most frequent malformations were renal ones; 27.7% of births were pre-term and 33.3% of those born weighed less than 2500g.  Conclusions:  The single umbilical artery is a marker for other malformations. When both coexist there is a risk of prematurity and low birth weight. Postnatal clinical examination is recommended for all newborns with single umbilical artery, checking for renal and heart defects.]]></p></abstract>
