inferior sagittal sinus

The transverse sinuses, sigmoid sinuses, occipital sinus, superior and inferior sagittal sinuses and the major intracranial veins, including the veins of Trolard and Labbe were assessed using a schematic approach.
Inferior sagittal sinus was seen in majority of cases (87.05%), but not visualised in all MRV examinations.
It receives the basal veins and the posterior fossa veins and drains to the anterior end of the straight sinus where this unites with the inferior sagittal sinus.
In group 1, localizations of CVT were superior sagittal sinus (n=2), superior sagittal sinus and transverse sinus (n=1), superior sagittal sinus and transverse sinus and sigmoid sinus (n=1), only transverse sinus (n=11), transverse sinus and sigmoid sinus (n=2), transverse sinus and inferior sagittal sinus (n=1), and only sigmoid sinus (n=3).
