El cordón umbilical luce normal pero solo se aprecian dos elementos vasculares: una arteria y una vena, en lugar de las dos arterias y una vena que es lo normal.
La razón de este nuevo estudio fue la presencia de dolor fuerte en fosa renal derecha, donde hemos apreciado dilatación hidronefrotica grado I, sin evidencia de litiasis reno-ureteral. El riñón izquierdo luce sonográficamente normal.
Arteria Umbilical Unica
Arteria Umbilical Unica ( AUU)
Pregnant patient of 27.0 weeks by last menstrual period date (LMP), first pregnancy. Sonographic examination is seen to male product development with estimated weight and gestational age according to sonographic. Not displayed malformations in head, chest, abdomen or extremities. The placenta and amniotic fluid, sonographic look normal. Product weight 1.082 grams. The umbilical cord looks normal but only shows two vascular elements: an artery and vein, instead of two arteries and one vein that is normal. This case had been diagnosed previously by other colleagues and he had made close study of the fetal heart con Doppler and was not found any defect associated with this condition. Statistically associates from 0.2 - 1.1% in pregnancies of a single product and is as high as 6 to 11% in case of multiple pregnancies. Furthermore there is greater risk of preterm delivery, intrauterine growth retardation (IUGR) and increased mortality peri-natal. In addition from 6,1 to 11.3% is associated with malformations associated with trisomy 18 to 13. The reason for this new study was the presence of severe pain right flank, where we appreciated hydronephrotic grade I dilatation without evidence of reno-ureteral lithiasis. The left kidney looks normal sonographic. In the images we appreciate the umbilical cord Doppler color change seen in only one artery and vein.
