Whether an ischemic stroke is due to a noncardiogenic or cardiogenic source, the mechanism of causing a stroke is the same. Both sources are involved with the development of thrombi or emboli that move from their original source to the brain blocking blood flow in the process. Known as Virchow’s triad, venous stasis, vascular injury, and hypercoagulability are major components in the development of thrombi.

Asymptomatic cerebral thromboembolic events can be detected by Diffusion weighted magnetic resonance imaging after ACDF. The incidence of such events remains very rare despite the direct manipulation and associated alteration of common carotid artery flow dynamics 1).
