Sonographic incidence of uncoiled umbilical cords during the entire gestation

Introduction Pathology studies have reported that uncoiled umbilical cords (UC) are frequently present in certain conditions such as miscarriage, unexplained fetal death, aneuploidies, structural abnormalities and fetal distress. Therefore, it would be important to analyse UC angioarchitecture during antenatal sonography. However, no information is available on the sonographic incidence of such UC's in otherwise normal pregnancies. Materials and Methods Consecutive women with singleton gestation and with a normal fetus were eligible for the study. Each women was included only once. Color flow mapping was used to…
