Abstract:
With advances in diagnostic imaging, congenital anomalies of the inferior vena cava are being increasingly detected incidentally in asymptomatic patients. Double inferior vena cava is a relatively well-known anomaly, with an estimated prevalence rate of 0.2%-3%. In contrast, right double inferior vena cava-in which two inferior vena cava run parallel on the right side of the abdominal aorta-is extremely rare, with only a handful of reported cases. In this case, the spatial relationship between the two inferior vena cava-which was lateral-to-medial immediately below the renal veins-changed to dorsal-to-ventral at the level of the pelvic inlet. From an embryological perspective, we discuss the spatial relationship between the two inferior vena cava, drawing on previous reports.

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.

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...

Development of the Lymphatic System
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
