Vertebral artery location

. Vertebral artery location in relation to the vertebral body as determined by two-dimensional computed tomography evaluation. They cruise upward between the vertebral bodies and join to form the basilar artery. The basilar artery is part of the blood supply system for the brain and central nervous system.

Also it is surrounded by the venous plexus which form the vertebral vein at the lower part of the neck. The vertebral artery turns abruptly as it nears the midline and pierces the posterior atlantooccipital membrane and enters into the vertebral canal. The vertebral arteries usually arise from the first portion of the subclavian artery.

They supply blood to the pons the medulla and the cerebellum. To determine the margin of safety necessary to avoid vertebral artery laceration during central decompression and. The vertebral artery then extends posterior and medially in a horizontal groove on the upper surface of the posterior arch of C1.

The vertebral arteries arise from the subclavian artery and run through the transverse foramen of the upper six vertebrae of the neck. Remaining aware of the vertebral artery location on the preoperative imaging and by avoiding disorientation during the exposure and main procedure. Proximal to its bifurcation into the terminal branches PCAs the basilar artery gives off the superior cerebellar arteries that supply the lateral aspect of the pons and midbrain as well as the superior surface.

This study analyzed the precise two-dimensional location of the vertebral artery within cervical vertebrae as determined by measurements obtained from axial computed tomographic images of the cervical spine. While passing through the transverse foramina the vertebral artery is located anterior to the trunks of the cervical spinal nerves. The first branch of the vertebral artery located in its V4 segment is the posterior inferior cerebellar artery PICA.

Each vertebral artery usually gives off the posterior inferior cerebellar artery PICA. The vertebral artery generally arises from the superior-posterior aspect of the first part of the subclavian artery. At the top of the pons the basilar artery divides into 2 posterior cerebral arteries PCAs.

After exiting at the level of the first cervical vertebra its course changes from vertical to horizontal and then enters the skull through the foramen magnum. The basilar artery continues to supply blood to. A R Vaccaro Department of Orthopaedic Surgery Jefferson Medical College of Thomas Jefferson University Philadelphia Pennsylvania.

Eight sectioned specimens and 8 cadavers were used to evaluate the location of the vertebral artery in the cervicothoracic junction. It is formed where the two vertebral arteries join at the base of the skull. However in approximately 5-6 of cases the left vertebral artery arises directly from the aortic arch between the left common carotid artery and the left subclavian artery 7.

The results of the measurements showed that there was no significant difference between either sides at the C7-T1 junction in terms of all distances taken. If the artery has been injured the sequence of steps to follow include 1 rapid compression and tamponade 2 mobilization and visualization and 3 repair or ligation.
