May prompt targeted vascular imaging in select patients; leaves open whether routine auscultation improves outcomes in Level 5 evidence.
A continuous or systolic murmur over the carotid bulb can be an early sign of carotid artery insufficiency, prompting consideration for early surgery or anticoagulation.
Lamar Crevasse (1958) conducted a review in Carotid artery insufficiency. Routine auscultation of the head and neck was evaluated. Routine auscultation of the head and neck can reveal a localized continuous murmur over a partially occluded carotid bulb, serving as an early sign of carotid artery insufficiency.
