Insights
Physicians should recognize rare venocaval anomalies. A unique case presented combined duplicate superior vena cava and interrupted inferior vena cava, a first in English literature.
Area of Science:
- Vascular anatomy and congenital anomalies.
Background:
- Venocaval anomalies are infrequent and often asymptomatic.
- Awareness of these anomalies is crucial for clinical management.
- Specific anomalies like duplicate superior vena cava and interrupted inferior vena cava have distinct clinical implications.
Observation:
- A unique case involving concurrent superior vena cava and inferior vena cava anomalies was incidentally discovered.
- The patient presented with a duplicate superior vena cava and an interrupted inferior vena cava.
Findings:
- This represents the first reported instance in English literature of a single patient exhibiting both a duplicate superior vena cava and an interrupted inferior vena cava.
- The co-occurrence of these specific venocaval anomalies is exceptionally rare.
Implications:
- This case highlights the importance of recognizing and diagnosing venocaval anomalies, even when incidental.
- Understanding these anomalies is vital for procedures like cardiac imaging, surgery, and catheterization.
- The findings contribute to the literature on rare vascular variations and their potential clinical significance.
Abstract:
Venocaval anomalies are uncommon in the general population and often go unrecognized, but physicians should be aware of their significance. Duplicate superior vena cava should be identified during cardiac imaging, surgery, and catheter insertions. While interrupted inferior vena cava can predispose to thrombus formation, they protect against pulmonary embolism from lower extremity deep vein thrombosis. We describe a unique case of a patient in which combined superior vena cava and inferior vena cava anomalies were found incidentally. This is the first reported case of a duplicate superior vena cava and interrupted inferior vena cava in a single patient in English literature. This article also provides a literature review on the topic.

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...

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...
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.
