Supernumerary umbilical vessels are related to embryologic developmental defect of umbilical cord. These vessels can be seen varying numbers and types also partial or thoroughly. Extra vein is seen more common than extra artery, generally seen as four umbilical cord vessels (two veins, two arteries). This condition may accompany congenital malformations, poor obstetrics outcomes or well fetuses. Unlike the existing literature, a 22-year-old multiparous woman gave birth a healthy baby with spontaneous vaginal delivery at term. In the macroscopic examination of the umbilical cord was found to be 3 cm in a partial area, in microscopic examination multiple vessels (7 arteries, 5 veins) were found in this area. No information about umbilical cord vascular structure was found in prenatal ultrasonographies. Prenatal diagnosis of isolated supernumerary umbilical cord vessels tends to be overlooked; histopathologic examination is very important for detection of this abnormalities.
