3D model of cerebral veins. In human anatomy, the cerebral veins are blood vessels in the cerebral circulation which drain blood from the cerebrum of the human brain. They are divisible into external (superficial cerebral veins) and internal (internal cerebral veins) groups according to the outer or inner parts of the hemispheres they drain into.
The pathophysiology of cranial venous outflow obstruction involves the disruption of normal venous drainage from the brain. Cerebral veins play a crucial role in draining brain interstitial fluid (ISF), and their significance has been linked in various neurological conditions. [1] It can be caused by extrinsic or intrinsic anomalies. [7]
The veins puncture the relevant dural sinus, piercing the arachnoid and dura mater as bridging veins that drain their contents into the sinus. [5] The deep venous system. The deep venous system is primarily composed of traditional veins inside the deep structures of the brain, which join behind the midbrain to form the great cerebral vein (vein ...
The superficial middle cerebral vein (superficial Sylvian vein) begins on the lateral surface of the hemisphere. It runs along the lateral sulcus [1] to empty into either the cavernous sinus, [1] [2] or sphenoparietal sinus. [1] It is adherent to the deep surface of the arachnoid mater bridging the lateral sulcus. It drains the adjacent cortex. [2]
Testing for a malformed vein of Galen is indicated when a patient has heart failure which has no obvious cause. [9] Diagnosis is generally achieved by signs such as cranial bruits and symptoms such as expanded facial veins. [4] The vein of Galen can be visualized using ultrasound or Doppler. [4] A malformed Great Cerebral Vein will be ...
Cerebral venous sinus thrombosis (CVST), cerebral venous and sinus thrombosis or cerebral venous thrombosis (CVT), is the presence of a blood clot in the dural venous sinuses (which drain blood from the brain), the cerebral veins, or both. Symptoms may include severe headache, visual symptoms, any of the symptoms of stroke such as weakness of ...
The superficial cerebral veins are a group of cerebral veins in the head. This group includes the superior cerebral veins , the superficial middle cerebral vein , the inferior cerebral veins , the inferior anastomotic vein and the superior anastomotic vein .
A vascular malformation is a type of vascular anomaly. [2] They may cause aesthetic problems as they have a growth cycle, and can continue to grow throughout life. Vascular malformations of the brain include those involving capillaries, and those involving the veins and arteries.
