Bridging vein

Bridging Vein

The Bridging Vein is a type of vein that connects the cerebral cortex and the dura mater, two important structures in the human brain. These veins are crucial for the proper functioning of the brain as they facilitate the drainage of blood from the brain's surface to the dural sinuses.

Structure

Bridging veins are typically 1-3mm in diameter and are located in the subarachnoid space. They are vulnerable to injury due to their location and the lack of supportive tissue surrounding them. The veins are most commonly found in the superior sagittal sinus, but can also be found in the transverse sinus and sigmoid sinus.

Clinical Significance

Due to their location and lack of supportive tissue, bridging veins are susceptible to trauma, which can lead to a subdural hematoma. This is a serious condition where blood collects between the layers of tissue that surround the brain, causing increased pressure and potential damage to brain tissue.
