To examine the development of the diploic veins in the calvarium, FITC-dextran was injected into the tail vein. The total area of the diploic veins showed a continuous, age-dependent development. We also measured the red blood cell (RBC) velocities in the diploic veins using an in vivo imaging technique and revealed RBCs with a significantly high velocity and unidirectional characteristics at the entrance route. The route passed from the basal periosteum of the cranial bone via the dura mater and into the diploic veins. Our findings indicate the existence of communications between intra- and extra-cranial circulation.
