The vertebral vein is a paired vessel found in the transverse foramina of the cervical vertebrae on either side of the neck. It arises at the level of the sixth cervical vertebra from a venous plexus that surrounds the vertebral artery and travels as far as the brachiocephalic veins. The vertebral vein is formed in the suboccipital triangle, from numerous small tributaries which spring from the internal vertebral venous plexuses and issue from the vertebral canal above the posterior arch of the atlas.. They unite with small veins from the deep muscles at the upper part of the back of the neck, and form a vessel which enters the foramen in the transverse process of the.

The vertebral column is drained by plexuses (networks) of veins. These venous plexuses are formed by spinal veins along the vertebral column, both inside and outside the vertebral canal. The plexuses include: Internal vertebral venous plexus (or the epidural venous plexus) External vertebral venous plexuses Anterior internal vertebral venous plexus The vertebral vein descends in the foramina transversaria of the upper six cervical vertebrae and forms a plexus around the vertebral artery. After emerging from the foramen transversarium of the sixth cervical vertebra, the vertebral vein descends anterolateral to the vertebral artery. It passes behind the internal jugular vein and anterior to. Structure and Function The spinal venous system consists of the intrinsic, extrinsic, and extradural systems. During IVC occlusion, the spinal venous system can serve as a collateral drainage system due to its connection with both pelvic and cranial veins. [1] a -centripetal network of veins, predominantly draining the gray matter into: b - central (sulcal) veins of the intrinsic system; c - peripheral (radial, a.k.a. marginal) centrifugal veins of the intrinsic system; d - venous anastomosis between the centripetal and centrifugal systems; e - anterior (ventral) median vein; f - posterior (dorsal) me.

The blood supply to the vertebral canal is critical especially from the context of surgical and clinical considerations. The spinal cord located within the vertebral canal allows for a neuronal connection between the brain and the rest of the body and thus the blood supply to this structure is of vital importance. In this review, we go over the blood supply as well as additional information. Vena vertebralis anterior Quick Facts Origin Course Tributaries Structures Drained Quick Facts Origin: Around the transverse processes of the upper cervical vertebrae. Course: Descends in the neck to drain into the vertebral vein. Tributaries: Anterior external vertebral venous plexus. Drainage: Vertebral column. Complete Anatomy The lumbar veins are four pairs of blood vessels that drain the lumbar segments of the spinal cord, posterolateral abdominal wall and lumbar structures of the back. They usually empty into the inferior vena cava, but they can also drain into the ascending lumbar, azygos, renal or other lumbar veins. This article reviews the arterial and venous anatomy of the spine and spinal cord. Special emphasis is placed on vessels critical to the conduct and interpretation of spinal angiography, notably the intersegmental artery and its cranial and caudal derivatives: the vertebral, supreme intercostal, and sacral arteries.

In the neck, the plexus drains to the vertebral vein and deep cervical veins [ 1 ]. In summary, the venous drainage of the spinal cord consists of internal cord veins, longitudinal cord veins, and radicular veins. Internal cord vein anatomy differs depending on the spinal segment; however, most drain centrifugally (with a radiating pattern. Description The vertebral venous plexuses are the network of veins that surround the vertebral column along its entire length. It is a nonuniform network of vessels located inside the vertebral column and immediately outside the vertebrae, primarily concentrated in anterior and posterior locations.
Starting at vertebral levels T12-L2, the azygos vein travels posterior to the right root of the lung (T5-T6) and arches superiorly over the root of the lung, emptying into the SVC. Sometimes, the azygos vein may travel higher to drain into the brachiocephalic or right subclavian vein. The vertebral venous plexus is a highly anastomotic network of valveless veins running along the entire length of the vertebral column from the foramen magnum to the sacral hiatus. Gross anatomy The vertebral venous plexus is comprised of three interconnected divisions: internal vertebral venous plexus external vertebral venous plexus

The vertebral vein (Latin: vena vertebralis) is a venous blood vessel that is formed by numerous small tributaries arising from the internal vertebral plexuses. The vertebral vein collects venous blood mainly from the upper deep muscles of the back.
