Summary
Persistent right umbilical vein (PRUV) is a common prenatal venous anomaly. A rare extrahepatic variant (E-PRUV) case showed a good outcome due to paraumbilical vein shunting, improving prognosis.
Area of Science:
- Medical science
- Fetal medicine
- Vascular anomalies
Background:
- Persistent right umbilical vein (PRUV) is a frequent prenatal diagnosis.
- Intrahepatic PRUV (I-PRUV) involves fusion with the portal vein, draining via the ductus venosus.
- Extrahepatic PRUV (E-PRUV) bypasses the liver, often associated with poor prognosis due to hemodynamic issues or malformations.
Observation:
- A case of E-PRUV with a positive outcome is presented.
- Prenatal ultrasound at 33 weeks identified E-PRUV draining into the inferior vena cava.
- The neonate, born at 35 weeks, showed no malformations or hemodynamic compromise, with enlarged paraumbilical veins noted postnatally.
Findings:
- The case demonstrates a favorable outcome for E-PRUV.
- Paraumbilical vein shunting may mitigate cardiac overload in E-PRUV.
- This shunt mechanism potentially improves the prognosis of E-PRUV.
Implications:
- This case suggests a potential protective mechanism in E-PRUV.
- Understanding paraumbilical vein shunting can refine prognostic assessments for fetal venous anomalies.
- Further research into hemodynamic compensation in E-PRUV is warranted.

1.4K
The human body is a complex system of interconnected parts, and the circulatory system plays a crucial role in maintaining overall health. One key component of this system is the inferior vena cava, a large vein responsible for returning blood from the abdominopelvic viscera and abdominal walls to the heart.
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...

The azygos system is a crucial part of the body's circulatory system and drains most of the thorax. It comprises the azygos, hemiazygos, and accessory hemiazygos veins.
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.

Systemic veins are crucial blood vessels that return deoxygenated blood from various body tissues back to the heart. There are three systemic veins that return deoxygenated blood to the heart, they are as follows.
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...

01:19Abdominal Regions and Quadrants
15.2K
To promote clear communication, for instance, about the location of a patient's abdominal pain or a suspicious mass, anatomists and clinicians typically use imaginary lines to categorize the abdominopelvic cavity into either four quadrants or nine regions to identify organs in the cavity.
The simpler quadrants approach, which is more commonly used in medicine, subdivides the cavity with one horizontal and one vertical line that intersects at the patient's umbilicus (navel). The four...

Fetal circulation is a unique system that facilitates the exchange of gases, nutrients, and waste products between the developing fetus and the mother. This intricate process takes place through a special organ called the placenta.
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...

Varicose veins, or varicosities, are abnormally dilated and twisted superficial veins caused by venous valve incompetence. This condition commonly affects the lower extremities, especially the saphenous veins, due to the higher pressure from prolonged standing and walking. However, varicosities can also occur in other areas, such as the esophagus, vulva, spermatic cords, and anorectal region.Etiology and typesPrimary varicose veins, often idiopathic, are more common in women due to inherent...
