Information About

Oliver's Sign




The tracheal tug sign ('''Oliver's sign''') can be elicited by asking the patient to sit with the head extended while grasping the Cricoid Cartilage and applying upward pressure. A downward tug of the Trachea synchronous with each Systole reveals the presence of an Aortic Arch Aneurysm . This occurs due to the anatomic position of the aortic arch, which overrides the left main Bronchus .
