FIGURE.
A, Cadaveric preparation showing a bridging vein (thick blue arrow) reaching the dura (blue arrow) at the lateral wall of the superior sagittal sinus and falx (yellow arrows), continuing (incomplete silicon penetration), embedded into the dura (multiple short blue arrows) to its piercing point (thin blue arrow), where it enters the sinus. Even macroscopically, one may see the bridging vein buried, not just adherent to and still easily distinguishable from the dura. The vein can be microsurgically prepared and separated from the dura, as it is shown in B (photo slightly tilted to the right compared with A).
