Vertebral Artery Anatomy Anatomical Charts & Posters
The vertebral column (spine or backbone) is a curved structure composed of bony vertebrae that are interconnected by cartilaginous intervertebral discs. It is part of the axial skeleton and extends from the base of the skull to the tip of the coccyx. The spinal cord runs through its center.

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.
Vertebral Artery Segments, Stenosis and Artery Dissection Symptoms
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.

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.

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.

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

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.

Spinal Vascular Malformations. This section is intended as an introduction to the (daunting) topic of spinal vascular anatomy. As interventionalists, we usually deal with two broad types of spinal issues — various vascular malformations and tumors. In the former group, we are mainly concerned with fistulas (dural, pial, cord) — not because.

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.

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.

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.

The vertebral vein is a paired blood vessel that is found on either side of the neck. As a single vessel, it is formed at the level of the sixth cervical vertebra (C6). Its initial part is a venous plexus that goes through the transverse foramina of the cervical vertebrae. Check it out
