Emissary veins (skull) 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). They are thin-walled and valveless The 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 The emissary vein of the foramen of Vesalius is a small vessel, which may not always be present because it has been omitted in the majority of descriptions of the human cranial venous system. In contrast, the interpterygoid vein of rats is a prominent channel (1 to 1.6 mm in diameter) The emissary veins are valveless vessels which connect the superficial veins of the scalp with deeper veins, e.g. diploic veins of the skull bones. From: Essential Clinical Anatomy of the Nervous System , 201 Occipital Emissary Vein The occipital emissary vein connects the transverse sinus to theoccipital vein, which then drains blood to the vertebral venousplexus (Figure 1A).3,6On occasion, the occipital emissary veinjoins the transverse-sigmoid sinus complex.16Okudera et al17reported that the occipital vein may drain to the confluenceof sinuses

RESULTS: Marked increase in venous flow from the rapidly growing cerebral hemispheres leads to ballooning of the transverse sinuses in the absence of an increase in the inner diameters of the sigmoid and jugular sinuses. The ballooning also results in formation of the occipital sinus, marginal sinus around the foramen magnum, and emissary veins Diploic veins in the cranial diploë. The diploë of the cranial bones contains a web of small corridors called diploic channels. Diploic channels house the diploic venous system which collects the venous blood from the diploë.
