Methods: VCTDSA data that matches research inclusion criteria of 102 patients with cephalocervical and cephalic scanning in our hospital from February 2007 to December 2008 were analyzed . The morphology of original point，output forms and the diameter of superior sagittal sinus were studied.. The number of tributaries veins，the anastomosis of superior sagittal sinus with other sinus were observed. Results: The original point of superior sagittal sinus was dead end accounting 40.2%，59.8% was converged by veins. The output branching as superior sagittal sinus lateralization，straight-sinus type at most (48.0%、49/102)，double branching type secondly (36.3%、37/102)，and confluens sinus type only 12.7%（13/102）.The section of superior sagittal sinus was triangle at most( 79.4%、81/102）Trolard anastomosis in 106， Labbe anastomosis in 155，and anastomosis between superior sagittal sinus and falciform sinus、s
