Superior Vena Cava Syndrome

Superior vena cava syndrome occurs when the superior vena cava, the large vessel that carries blood from the upper part of the body back to the heart, becomes obstructed or compressed. This hinders the return of blood and produces characteristic signs in the head, neck, and arms.

Common symptoms: swelling of the face, neck, or arms, dilation of superficial veins, a sensation of fullness in the head and, at times, difficulty breathing.

When to see a doctor? In the presence of facial swelling that appears or increases, especially if accompanied by difficulty breathing, prompt attention is advisable.

Which specialist treats it? The cardiologist and the cardiovascular and thoracic surgeon take part in its evaluation; in children the pediatric cardiologist is involved. Faced with these signs, the most sensible course is to seek a timely professional evaluation.
