Intraabdominal Aneurysm of the Umbilical Vein of the Fetus. (A Rare Clinical Case)

Abstract

The umbilical cord is an extension of the fetal cardiovascular system. According to all available scientific data, umbilical cord abnormalities play an important and often decisive role in the development of complications during pregnancy and childbirth, including perinatal mortality. Thus, umbilical cord abnormalities include skinny umbilical cord, umbilical cord presentation, absolutely short umbilical cord, sheath attachment of the umbilical cord, presentation of umbilical cord vessels, hypoisvite and hyperisvite umbilical cord, single umbilical artery, persistence of the right umbilical vein, vein aneurysm and umbilical cord hematoma. There are several variants of localization of this vascular anomaly: in the area of attachment to the placenta, in the free part, in the area of the umbilical ring and in the intraabdominal (intrahepatic) part. There are no clinical recommendations for the management of pregnancy with an umbilical vein aneurysm. When detecting umbilical cord abnormalities, it is necessary to monitor the dynamics of changes in the size of the aneurysm with an assessment of the fetal condition. The article describes a clinical case of intraabdominal fetal umbilical vein aneurysm, which is extremely rare and accounts for less than 1% of all umbilical cord abnormalities. The patient's reproductive and genetic history is not burdened. The somatic history was aggravated by neurodegenerative diseases of the spine. The pregnancy proceeded against the background of repeated threats of termination of pregnancy and anemia.
