Superior vena cava syndrome (SVCS)

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.
