Notes

The diploic veins are a network of veins located within the diploë, the spongy bone layer between the inner and outer layers of the cranial bones. These veins are responsible for draining the bone marrow and the spongy bone of the skull.

Anatomy

The diploic veins are situated within the cranial vault and are primarily found in the frontal, parietal, temporal, and occipital bones. They are connected to the dural venous sinuses, which are channels that drain venous blood from the brain and meninges into the internal jugular vein.

Function

The primary function of the diploic veins is to facilitate the drainage of blood from the diploë into the dural venous sinuses. This process helps in maintaining the intracranial pressure and ensures proper cerebral circulation.

Clinical significance

The diploic veins can be involved in various pathological conditions. For instance, they may become engorged or thrombosed in cases of increased intracranial pressure or cranial trauma. Additionally, these veins can serve as pathways for the spread of infection or metastatic disease to the cranial cavity.
