Where is the inferior vena cava?

The IVC lies along the right anterolateral aspect of the vertebral column and passes through the central tendon of the diaphragm around the T8 vertebral level. The IVC is a large blood vessel responsible for transporting deoxygenated blood from the lower extremities and abdomen back to the right atrium of the heart.

What is the function of the inferior vena cava quizlet?

What is left SCV?

Background. Persistent left superior vena cava (PLSVC) is a rare vascular anomaly that begins at the junction of the left subclavian and internal jugular veins, passes through the left side of the mediastinum adjacent to the arcus aorta. It mostly drains into the right atrium via the coronary sinus (CS).

What side is the SVC on?

What is SVC syndrome?

Superior vena cava syndrome (SVCS) is a group of problems caused when blood flow through the superior vena cava (SVC) is slowed down. The SVC is a large vein that drains blood away from the head, neck, arms, and upper chest and into the heart. SVCS is most often seen in people who have cancer.

How many people are born without an inferior vena cava?

AIVC has an incidence of 0.0005% to 1% in the general population (6). During weeks 6 to 10 of gestation, anomalies of the IVC may occur.
