Key result
Superior vena cava syndrome results from obstruction of the superior vena cava, leading to clinical signs such as upper body edema, jugular vein distension, and prominent collateral veins.
Superior vena cava syndrome presents with symptoms such as headache, dysphagia, hoarseness, and shortness of breath due to obstruction of the superior vena cava.
Recognizing classic SVC signs prompts urgent evaluation; leaves open optimal imaging protocols in contemporary practice.
Superior vena cava syndrome (SVCS) consists of a constel-lation of symptoms that result from some degree of obstruction of the superior vena cava (SVC). The SVC is formed by the union of the left and right brachiocephalic veins and ends with the continuation into the right atrium of the heart. The SVC's function of returning blood from the upper half of the body, and its location anterior to the trachea at the right margin of the sternum, helps explain the typical signs and symptoms of the superior vena cava syndrome. The patient with superior vena cava syndrome might complain of head-ache, dysphagia, hoarseness, or shortness of breath. Blockage of the SVC can lead to clinical signs such as upper body edema, plethora, jugular vein distension, and appearance of prominent collateral veins.
