I measured the volumetric velocity of blood flow (flow, fluid flow) three times on a Doppler scan from an ultrasound specialist I know. A manual angle correction was performed (I checked it myself, otherwise all measurements are incorrect without correct angle correction). The measurements were carried out with a time interval of 3-6 months. All measurement values were practically the same (identical). What I got:
The vertebral arteries are 40-45 ml/min each (with a standard of about 80 ml/min per vertebral artery). On the common carotid artery 180-230 ml/min (with a standard of about 330-380 ml/min per CCA, with a standard of about 250 ICA). This indirectly indicates that outflow is difficult (when there is compression on both sides, right and left). But you should not accept Doppler scanning as a standard for diagnostic research. I’ll give you an example, but this is a theoretical assumption. According to the physical laws of hydrodynamics, a liquid flows in large proportions where there is less resistance (compression is resistance). When you have almost completely compressed one side, the brachiocephalic left vein, and the collateral veins, the vena thyroidea inferior, are not developed (for example, between the aortic arch and the sternum), and the right side is open, most of the blood will flow along the right side. And on a Doppler scan of the blood flow in the arteries, everything will be normal (except for a slight decrease in the flow along the left vertebral artery, and it will most likely be hypoplasticized, slightly thinner). What happens in this case (once again, this is an assumption, a theory):
Blood flow (blood flow) most of it flows on the right side, while “stagnation” appears - a low blood flow rate in the area of the cerebellum on the left. Therefore, dizziness may occur in this case . And having performed a surgical operation in the C1 area, you will get almost no effect, and you need to solve the problem in the area of the upper exit of the thoracic aperture (expand the aperture, or do an anamastosis).
