Pemberton's sign
Pemberton's sign is the development of facial flushing,[1] distended neck and head superficial veins, inspiratory stridor and elevation of the jugular venous pressure (JVP) upon raising of the patient's both arms above his/her head simultaneously, as high as possible (Pemberton's maneuver).
It is named for Dr. Hugh Pemberton, who characterized it in 1946.[2][3]
Causes
A positive Pemberton's sign is a sign of superior vena cava syndrome, possibly from a mass in the mediastinum, such as a tumor[citation needed] or goiter[4] (thoracic inlet obstruction due to retrosternal goitre or mass).
Apical lung cancers often cause a positive Pemberton's sign and a high index of suspicion should be maintained in patients with symptoms of dyspnea and facial plethora with an extensive smoking history.
