Emissary veins - Wikipedia
Emissary veins have an important role in selective cooling of the head. They also serve as routes where infections are carried into the cranial cavity from the extracranial veins to the intracranial veins. There are several types of emissary veins including the posterior condyloid, mastoid, occipital and parietal emissary veins. [1]

Nov 3, 2023 · Emissary veins are valveless venous vessels that connect the extracranial and intracranial venous systems. Note that the term emissary means “bridging” and in anatomy, it is used as an adjective rather than a proper name for every vein that establishes a connection between the dural venous sinuses and the veins external to the skull.

Jul 25, 2023 · Emissary veins are valveless venous structures that connect the extracranial vessels of the scalp to the intracranial dural venous sinuses and diploic veins. The presence and distribution of the emissary veins vary from person to person, and during childhood, these venous structures are found more frequently and with larger foramina.

Apr 20, 2022 · Emissary veins (also known as the vena emissaria) are veins which pass through foramina in the skull to provide a venous communication between the dural venous sinuses and veins of the scalp or veins inferior to the skull base (cranial-cerebral anastomosis).
Emissary Veins - neuroangio.org
Emissary veins are just quasi-random holes in the skull, serving as outflow for (usually) sinus blood. There is rationale to this, however — they are in balance with the “typical” outflow — sigmoid sinuses via jugular foramina, and other ways …
Why should we report posterior fossa emissary veins? - PMC
The mastoid emissary vein, condylar veins, occipital emissary vein, and petrosquamosal sinus are the major posterior fossa emissary veins. We believe that posterior fossa emissary veins can be detected by radiologists before surgery with a thorough understanding of their anatomy.

Dec 8, 2023 · Emissary veins serve as connections between the intracranial and extracranial venous systems. They are characteristically thin walled with a valveless structure. In the posterior fossa, several emissary veins connect the dural sinuses and extracranial veins.

Jan 23, 2025 · Emissary veins are small veins that connect the venous system inside the skull (intracranial venous sinuses) with the veins outside the skull (extracranial veins). These veins serve as channels between the dural venous sinuses, located within the dura mater, and the veins of the scalp, face, and neck.
Aug 20, 2023 · Emissary veins are valveless veins which pass through skull foramina connecting the intracranial dural venous sinuses to the extracranial veins. They equalize the venous pressure on both sides of the cranium, cool the brain, and may transmit extracranial infection to …
