Abstract:

Objective  The purpose of this study was to determine the anatomical features of venous sinus in clinic using subtraction computed tomography angiography (CTA) technique.  Methods  A total of 105 images of venous sinus were obtained by three-dimensional reconstruction after CT angiography of head, to determine the anatomical information of the venous sinus.  Results  The superior sagittal sinus is below the coronal suture. The posterior segment of the superior sagittal sinus is most prominent in the partial right compared with the line lambda to the occipital protuberance. The deviation of the center of the sinus confluence is consistent with the deviation of the posterior segment superior sagittal sinus. The right side of transverse sinus, transverse-sigmoid sinuses transition and sigmoid sinus are larger than the left. With the increase of transverse-sigmoid sinuses transition and sigmoid sinus, the distance between venous sinus and skull or mastoid surface and external auditory canal is smaller.  Conclusions  Subtraction CTA and merged images provide a feasible method to identify the anatomical relation between venous sinus and surface landmarks of cranium. Subtraction CT angiography is a reliable method in the anatomical features of the venous sinus for surgical craniotomies.
