Venous drainage dominance of the dural venous sinuses may be defined as the drainage only or mainly into one of the transverse sinuses, as shown by bilateral carotid angiography. The aim of this study was to evaluate the venous drainage dominance in bilateral carotid angiograms of 189 cases retrospectively. Among these cases 41.3% showed drainage mainly to the right side, 37.6% showed equal drainage to each side, 18.5% showed drainage mainly to the left side, 2.1% showed drainage only to the right side and 0.53% showed drainage only to the left side. Cerebral venous drainage dominance is of great importance and should be considered before operations on patients for radical neck dissection, removal of tumors in the neck that invade the internal jugular vein or tumors of the glomus jugulare which may require ligation of the internal jugular vein.
