  2. Definitions
    1. Cerebral Sinus
      1. Cerebral Sinuses are the venous return of the Central Nervous System (CNS)
      2. Venous channels (sinuses) drain ultimately into the Jugular Vein
  3. Background

    2. Cerebrospinal fluid drainage
      1. CSF starts in the Cerebral Ventricles (produced in Choroid plexus of Lateral Ventricles)
      2. CSF enters the sinuses via the arachnoid villi of the Superior Sagittal Sinus, Straight Sinus and occipital sinus
      3. CSF ultimately enters Transverse Sinuses and drains into the bilateral internal Jugular Veins
    3. Venous sinuses
      1. Encased in the dura matter (outer Meninges)
      2. Separated from the arteries within the pia matter (inner Meninges) by the intervening arachnoid layer

  4. Anatomy: Major Cerebral Sinuses
    1. Superior Sagittal Sinus
      1. Drains cerebrospinal fluid
      2. Saggital sinus thrombosis may occur (presenting with severe Headache)
    2. Cavernous Sinus
      1. Drains venous blood from the eye
      2. May act as a conduit for spreading infection intracranially from Orbital Cellulitis, other serious facial infections
    3. Transverse Sinus
      1. Runs in the vicinity of the ear (with risk of contiguious spread from inner ear infections)
  5. Anatomy: Other Cerebral Sinuses
    1. Inferior Sagittal Sinus
      1. Contained in the falx cerebri
    2. Straight Sinus
      1. Contained in the tentorium cerebelli
  6. Pathophysiology
    1. Venous Sinus Thrombosis
      1. As with other veins, venous thrombosis may affect cerebral veins
      2. Presents with Headache, Vision change and stroke-like symptoms
    2. Cavernous Sinus Complications
      1. Risk of infection (spread from orbital veins), compression (e.g. Pituitary Adenoma) and thrombosis
      2. Risk of neurovascular injury or compression

Cranial Sinuses (C0010271)

Definition (NCI) Venous channels within the dura mater of the brain which receives both blood from blood vessels within the brain as well as cerebrospinal fluid then drains into the internal jugular vein. Unlike other blood vessels, dural venous sinuses lack valves and other vessel associated layers.
Definition (NCI_CDISC) Venous channels within the dura mater of the brain which receives both blood from blood vessels within the brain as well as cerebrospinal fluid then drains into the internal jugular vein. Unlike other blood vessels, dural venous sinuses lack valves and other vessel associated layers.
Definition (MSH) Large endothelium-lined venous channels situated between the two layers of DURA MATER, the endosteal and the meningeal layers. They are devoid of valves and are parts of the venous system of dura mater. Major cranial sinuses include a postero-superior group (such as superior sagittal, inferior sagittal, straight, transverse, and occipital) and an antero-inferior group (such as cavernous, petrosal, and basilar plexus).

Superior sagittal sinus (C0226859)

Definition (MSH) The long large endothelium-lined venous channel on the top outer surface of the brain. It receives blood from a vein in the nasal cavity, runs backwards, and gradually increases in size as blood drains from veins of the brain and the DURA MATER. Near the lower back of the CRANIUM, the superior sagittal sinus deviates to one side (usually the right) and continues on as one of the TRANSVERSE SINUSES.
Definition (NCI) An intracranial venous sinus that lies in a superior and midline location above the interhemispheric fissure along the superior border of the falx cerebri of the brain. The sinus receives blood from the cerebral veins and drains posteriorly into the lateral sinuses of the brain, which in turn drain into the internal jugular veins.

Structure of transverse sinus (C0226864)

Definition (MSH) The two large endothelium-lined venous channels that begin at the internal occipital protuberance at the back and lower part of the CRANIUM and travels laterally and forward ending in the internal jugular vein (JUGULAR VEINS). One of the transverse sinuses, usually the right one, is the continuation of the SUPERIOR SAGITTAL SINUS. The other transverse sinus is the continuation of the straight sinus.
