Background: Carotid sinus massage is widely used to detect carotid sinus hypersensitivity in patients presenting with syncope. Recent guidelines recommend 5 to 10 seconds of carotid sinus massage in supine and upright positions with beat-to-beat monitoring, but somebody did not respond to the procedure.
Method and result: The aim of this study was to describe the common Carotid Artery Bifurcation (CB). Measurements were performed on 100 cadavers by the direct inspection method. The vertebra level of CB was differently distributed in distance of the whole neck measured along the vertebral column between upper borders of C1-C2 to lower border of C5. 54% of the level of CB was asymmetrical between the right and left side.
Conclusion: We showed the anatomical variation of carotid sinus location. Anatomical locations of the carotid sinus bifurcation indicated wide variability. This variation was found to have an impact on the pressure transmission at the carotid sinus region in those individuals that displayed the superior/inferior range of carotid sinus loci.
