Abstract:
The anomalies of the umbilical vessels are uncommon, with the exception of a single umbilical artery. We report a term female infant with fetal hydrops, hypertrophic cardiomyopathy, and a four-vessel umbilical cord consisting of two umbilical arteries and two umbilical veins. The presence of two veins in the umbilical cord has been attributed to persistence of both the normal left umbilical vein and the caudal part of the right umbilical vein. This fetal vascular pathology has been reported very rarely and may be associated with increased risk of congenital malformations and adverse perinatal outcome.

Fetal Circulation
Two umbilical arteries transport blood from the fetus to the placenta. At the placenta, the blood absorbs oxygen and nutrients while simultaneously eliminating waste products. This oxygen-enriched and nutrient-rich blood then returns to the fetus through one...
Overview of Systemic Veins
The coronary sinus, the heart's principal vein, resides in the coronary sulcus on the heart's posterior aspect. This broad venous channel receives nearly all venous blood from the myocardium, the heart muscle. It is fed by three primary veins: the great cardiac vein, the middle...
Veins of the Abdomen and Pelvis
The inferior vena cava is fed by numerous smaller veins. The lumbar veins, for instance, drain the posterior abdominal wall, emptying both directly into the inferior vena cava and into the...
Veins of Thorax
The azygos vein, positioned just right of the midline and anterior to the vertebral column, begins at the junction of the right ascending lumbar and subcostal veins, terminating in the superior vena cava. This vein drains blood from the right side of the thoracic wall, thoracic viscera, and posterior abdominal wall.
