Advanced imaging and management of superior vena cava syndrome.

Abstract

Superior vena cava (SVC) syndrome results from stenosis and/or occlusion of the central venous system leading to symptomatology associated with head and neck as well as upper-extremity venous congestion. With the rise in central venous catheter use and increasing cases of malignancy, the incidence of SVC syndrome has steadily increased in recent years. This narrative review explores the clinical presentation of SVC syndrome, alongside its evolving etiologies within modern clinical practice and its pathophysiology. In light of this, advanced imaging modalities and management approaches are discussed based on the extensive institutional experience, detailing the preprocedural imaging techniques, conservative and interventional treatment options, and follow-up imaging protocols.
