[Microsurgical anatomy and DSA research about venous anastomosis of superficial cerebral veins].
OBJECTIVE
To investigate the distribution and clinical significance about venous anastomosis of superficial cerebral vein in normal adult.


METHODS
The digital subtraction angiography (DSA) images of the venous phase from 50 normal adults were retrospectively analyzed, and the morphology of venous anastomosis of superficial cerebral veins was observed and measured. While venous anastomosis of superficial cerebral veins of 15 (30 sides) cadaveric heads was observed through blood vessel perfusion.


RESULTS
Trolard vein and Labbe vein were the main venous anastomosis of superficial cerebral veins. A total of 55 Trolard veins were found out of 50 sides DSA venous phase images, including left 27, right 28; 34 Trolard veins, left 18, right 16, were found from the 30 sides of the brain hemispheres. 51 Labbe veins, left 25, right 26, were found from the 50 sides DSA venous phase images, and 31 Labbe veins, left 15, right 16, were found from the 30 sides of the brain hemispheres.


CONCLUSIONS
Venous anastomosis of superficial cerebral veins is variable. The DSA venous phase image is consistent with the microscopic anatomy, and the preoperative DSA examination is beneficial for the protection of venous anastomosis of superficial cerebral veins.
