The biomechanical behaviour of the bridging vein-superior sagittal sinus complex with implications for the mechanopathology of acute subdural haematoma

General view of the BOSE test bench used to perform the mechanical tests and a close-up of a BV specimen fixed between the laparoscopic grasps (Left); typical stress-strain curve experimentally derived and used to calculate the mechanical parameters and a schematic representation of the reference cross-sectional area of the BV (A0) used to calculate the yield and the ultimate stress parameters.321
