Oliver's sign, or thetracheal tug sign, is an abnormal downward movement of thetrachea duringsystole that can indicate a dilation oraneurysm of theaortic arch.
Oliver's sign is elicited by gently grasping thecricoid cartilage and applying upward pressure while the patient stands with their chin extended upward. Due to the anatomic position of the aortic arch, which overrides the left mainbronchus, a downward tug of thetrachea may be felt if an aneurysm is present.[1] It is also seen in lightanaesthesia.
The sign was first described byEnglish militarysurgeonWilliam Silver Oliver in 1878.[citation needed]
