New catheter for tortuous vertebral artery.
The difficulty of catheterizing markedly tortuous vertebral arteries is well known to cerebral angiographers. When catheterization by the transfemoral approach fails, a left retrograde brachial flush injection or transax illary vertebral catheterization may be performed as alternative techniques in opacifying posterior fossa vessels . These additional approaches can be obviated by using a J tip...
متن کاملAnatomical Variations of Vertebral Artery
Introduction: Vertebral arteries arise from the root of the neck as the first branches from the superior-posterior aspect of the subclavian arteries. They ascend the neck to enter the cranial cavity and supply blood to the brain. Methods: A total of 20 cadavers (in 10 years) were dissected for the study of variations in the origin of the vertebral artery. This study was conducte...
متن کاملAnatomy of the intervertebral foramen.
The intervertebral foramen serves as the doorway between the spinal canal and periphery. It lies between the pedicles of neighboring vertebrae at all levels in the spine. A number of categorization schemes have been attempted to describe the boundaries of the intervertebral foramen. No uniform agreement has been made on which classification best describes this area. Studies of the nerve root ca...
متن کاملVertebral artery injury during anterior cervical vertebral surgery caused by transverse foramen malformation-appendix: case report and literature review
One male patient at 59 years old of age was diagnosed as cervical myelopathy for unsteady gait and stiff lower limbs, followed by cervical 3/4 and 5/6 discectomy plus bone grafting and internal fixation, when processing the superior endplate of left cervical 4 disk, a large number of arterial bleeding occurred, which was stopped by packing method, and followed by continued cervical discectomy p...
متن کاملMeasurement of occlusion of the spinal canal and intervertebral foramen by intervertebral disc bulge
BACKGROUND Disc protrusion has been proposed to be a possible cause of both pain and stenosis in the lower spine. No previous study has described the amount of disc occlusion of the spinal canal and intervertebral foramen that occurs under different loading conditions. The objective of this study was to quantitatively assess the percent occlusion of the spinal canal and intervertebral foramen b...
