Superior vena cava syndrome

Abstract

Superior vena cava syndrome is the general name for the symptoms and presentation due to acute obstruction or occlusion of the superior vena cava flow. It usually develops secondary to underlying malignancies and is a life-threatening oncologic emergency. In this review, the current clinical approach to superior vena cava syndrome, including the etiologic considerations, investigations that should be planned, diagnosis, and treatment algorithms, is reviewed.
