Abstract:
Duplication of the inferior vena cava (IVC) is a rare anomaly that arises from abnormal venous development during embryogenesis, leading to two venae cavae instead of one. Although it is usually a clinically silent anatomical variant, this developmental anomaly may alter venous flow within the major venous vessels and cause pathological consequences. Despite being a rare cause of lower-extremity venous disease, it should be included in the differential diagnosis when evaluating a patient with venous disease of no obvious etiology. In this report, we describe an incidental finding of a duplicated IVC in a patient with a 14-year history of persistent left lower-extremity swelling.

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...

Jugular Venous Pressure (JVP) Measurement
Position the patient at a thirty- to forty-five-degree angle or in a semi-fowler's position. Look for the highest point of pulsation in the internal jugular vein and measure the vertical distance to the angle of Loius or sternal angle. A normal JVP is 3-4 cm above the...

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...
