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

Clin Imaging. 2012 Mar-Apr;36(2):85-9. doi: 10.1016/j.clinimag.2011.05.003.

Abstract

Objectives: The aim of the present study was to examine the superior sagittal sinus (SSS) and bridging veins (BVs) from an anatomical, neurosurgical and radiological perspective.

Methods: Computed tomography venographies (CTVs) of 30 patients and 9 cadaveric dissections of human SSS were analyzed.

Results: CTV 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).

Conclusions: Important anatomical information can be drawn from cerebral CTV for neurosurgical preoperative planning.
