Radicular artery - Wikipedia
The radicular arteries are crucial for adequate arterial supply of most of the spinal cord as the anterior and posterior spinal artery do not provide sufficient arterial supply to the spinal cord by themselves - with the exception of the cervical portion of the spinal cord.
Spinal cord: Blood supply and anatomy - Kenhub
2023年10月30日 · The anterior and posterior radicular arteries arise from spinal branches of the vertebral, ascending cervical, deep cervical, intercostal, lumbar and sacral arteries. These radicular arteries are arranged radially, and course alongside the dorsal and ventral roots of spinal nerves to pierce and supply blood to the spinal cord.

2023年8月8日 · Most radicular arteries disappear before birth; however, several dominant radiculomedullary ones remain, including the artery of Adamkiewicz. They also result in important collateral vessels for the spinal cord by forming anastomoses with the anterior and two posterior spinal arteries resulting in their common name of booster/feeder vessels.
The blood supply to the spine is based on a predictable segmental vascular structure at each spinal level, but true radiculomedullary arteries, which feed the dominant cord supply vessel, the anterior spinal artery, are relatively few and their locations variable.

2023年2月15日 · The great radicular artery, also known as the Artery of Adamkiewicz, is the largest radicular artery and is the major blood supply to the lower two-thirds of the spinal cord. It is generally located on the left side between T9-T12 (75% of cases), though it can be located anywhere between T7-L4 (Figure 4). 5
Radicular Arteries (Cervical; Left) | Complete Anatomy - Elsevier
The radicular arteries are small arteries that arise from lateral spinal branches of the vertebral, ascending cervical, intercostal, subcostal, and lumbar arteries. The radicular arteries pass medially to enter the intervertebral foramina at each vertebral level. They accompany the anterior and posterior root of the spinal cord.
Radicular Artery - an overview | ScienceDirect Topics
The Radicular Artery is defined as a branch of the segmental artery that supplies the nerve root and continues towards the midline of the anterior cord surface, connecting to the anterior spinal artery.
Radicular Artery - an overview | ScienceDirect Topics
Radicular arteries, deriving from the aorta, provide major anastomoses with the anterior and posterior spinal arteries and supplement the blood flow to the spinal cord. The largest of these anterior radicular arteries, often from the L2 region, is the artery of Adamkiewicz.
40: The Radiculopial and Radiculomedullary Arteries
2016年1月5日 · The radiculomedullary arteries supply the nerve root, the superficial pial system, and the medulla (via the anterior radicular artery). This classification offers advantages for the interventional neuroradiologist when compared with the classical differentiation because it stresses the importance of the anterior supply for the gray matter of ...
Blood Supply to the Spinal Cord | Physical Therapy - Oxford …
2001年6月1日 · The dorsal and ventral radicular arteries are also derived from the spinal branches of the ascending cervical, deep cervical, posterior intercostal, and lumbar arteries. These arteries course along most nerve roots (all except those supplied by a segmental medullary artery) and supply blood to the dorsal and ventral roots of the spinal nerves ...
