Effect of occipitoatlantal decompression on cerebral blood flow dynamics as evaluated by Doppler ultrasonography.

Conclusion: Increases in EDV occurred in major cranial arteries after OAD but not after sham touch, indicating that EDV improves blood flow to the brain. The exact mechanism of this increase is unknown; however, it can be explained by either parasympathetic stimulation through the secretion of vasodilating neurotransmitters or by a decrease in external tissue pressure on ICA and VA, with the resulting flow causing further dilation in the MCA.
