Can Superior vena cava syndrome causes facial swelling?

No, superior vena cava syndrome does not cause facial swelling.

Superior vena cava syndrome is a condition in which the superior vena cava (SVC) is obstructed, which prevents blood from returning to the heart from the upper body. This can cause a number of symptoms, including:

* Swelling of the face, neck, arms, and chest

* Shortness of breath

* Difficulty swallowing

* Hoarseness

* Cough

* Chest pain

* Lightheadedness

* Dizziness

* Fainting

Facial swelling is not a symptom of SVC syndrome because the SVC does not drain blood from the face. The facial veins drain blood into the internal jugular veins, which empty into the SVC. Therefore, an obstruction of the SVC would not cause facial swelling.
