Vein channel in the brain
Blood vessel
The superior petrosal sinus is one of the dural venous sinuses located beneath the brain . It receives blood from the cavernous sinus and passes backward and laterally to drain into the transverse sinus . The sinus receives superior petrosal veins, some cerebellar veins , some inferior cerebral veins , and veins from the tympanic cavity . They may be affected by arteriovenous malformation or arteriovenous fistula , usually treated with surgery .
Structure
The superior petrosal sinus is located beneath the brain. It originates from the cavernous sinus . It passes backward and laterally to drain into the transverse sinus .
The sinus runs in the attached margin of the tentorium cerebelli , in a groove in the petrous part of the temporal bone formed by the sinus itself - the superior petrosal sulcus.
Function
The superior petrosal sinus drains many veins of the brain, including superior petrosal veins,[ 1] cerebellar veins , some inferior cerebral veins , and veins from the tympanic cavity .
Clinical significance
The superior petrosal sinus may be affected by an arteriovenous malformation or arteriovenous fistula .[ 2] [ 2] endovascular surgery or open surgery .[ 2]
