Differential diagnosis | superior vena cava syndrome |
The Pemberton's sign is a physical examination tool used to demonstrate the presence of latent pressure in the thoracic inlet.[1] The sign is named after Hugh Pemberton, who characterized it in 1946.[2]
The Pemberton maneuver is achieved by having the patient elevate both arms (usually 180 degrees anterior flexion at the shoulder) until the forearms touch the sides of the face. A positive Pemberton's sign is marked by the presence of facial congestion and cyanosis, as well as respiratory distress after approximately one minute.[3]
