Variations of the superior sagittal sinus and bridging veins in human dissections and computed tomography venography

ObjectivesThe aim of the present study was to examine the superior sagittal sinus (SSS) and bridging veins (BVs) from an anatomical, neurosurgical and radiological perspective.MethodsComputed tomography venographies (CTVs) of 30 patients and 9 cadaveric dissections of human SSS were analyzed.ResultsCTV and cadavers showed most BVs emptying into the SSS close by (±3 cm) and distal to the coronary suture (74% in CTV, 62% in cadavers).ConclusionsImportant anatomical information can be drawn from cerebral CTV for neurosurgical preoperative planning.
