As outlined above the origin of the artery of Adamkiewicz is quite variable and can extend from mid-thoracic to lumbar levels 3 :. On CTA, it appears as a continuous vascular structure running from an intercostal or lumbar artery to the anterior spinal artery via the radiculomedullary artery with its characteristic course 2.

Phonetic spelling of artery of Adamkiewicz artery of adamkiewicz.Objective: The purpose of our study was to prospectively assess MDCT technology in combination with adapted brain reconstruction algorithms to visualize the spinal vasculature, in particular the artery of Adamkiewicz and its anatomic variants.
Subjects and methods: One hundred patients underwent contrast-enhanced MDCT of the thoracolumbar junction with collimation of 40 x 0. The adapted brain algorithm reconstructed the spinal canal with a field of view of 90 mm at 0. Curved multiplanar reformations identified the artery of Adamkiewicz as a continuous vascular tract extending from the aortic orifices of the intercostal or lumbar arteries via the anterior radiculomedullary artery to the anterior spinal artery.
Segment of origin and length were noted. Diameter and contrast-to-noise ratio CNR were evaluated along the posterior branch, the radiculomedullary artery, the artery of Adamkiewicz, and the anterior spinal artery. Univariate general linear model analysis with Bonferroni post hoc corrections evaluated whether laterality, segment of origin, and length of the artery of Adamkiewicz showed a sex-specific propensity.
Multivariate general linear model analysis assessed whether spinal vascular diameters and intraluminal CNR showed correlations with sex, laterality, and segment of origin. Finally, the luminal diameters of the feeding posterior branches were statistically compared with those of the ipsilateral and contralateral adjacent posterior branches.
Results: Successful depiction of the artery of Adamkiewicz was achieved in all patients; longitudinally the artery measured The diameter of the posterior branches 2. Conclusion: Contrast-enhanced MDCT technology, in combination with an adapted brain reconstruction algorithm, can depict the artery of Adamkiewicz and its anatomic variants. Abstract Objective: The purpose of our study was to prospectively assess MDCT technology in combination with adapted brain reconstruction algorithms to visualize the spinal vasculature, in particular the artery of Adamkiewicz and its anatomic variants.
Substances Contrast Media.In human anatomythe artery of Adamkiewicz also arteria radicularis magna is the largest anterior segmental medullary artery. It has several other names, including:. The blood supply of the spinal cord is complex and highly variable. When damaged or obstructed, it can result in a syndrome of spinal cord ischemia, similar to anterior spinal artery syndrome with loss of urinary and fecal continence and impaired motor function of the legs; sensory function is often preserved to a degree.
It is important to identify the location of the artery when surgically treating an aortic aneurysm to prevent damage which would result in insufficient blood supply to the spinal cord. It is named for Albert Wojciech Adamkiewicz. From Wikipedia, the free encyclopedia.

The aim of this study was to provide comprehensive data on the prevalence and anatomical characteristics of the AKA. Methods: An extensive search was conducted through the major electronic databases to identify eligible articles. Data extracted included study type, prevalence of the AKA, gender, number of AKA per patient, laterality, origin based on vertebral level, side of origin, morphometric data, and ethnicity subgroups.
Our main findings revealed that the AKA was present in Conclusion: As an AKA is present in the majority of the population, caution should be taken during vascular and endovascular surgical procedures to avoid injury or ensure proper reconstruction. All surgeons operating in the thoracolumbar spinal cord should have a thorough understanding of the anatomical characteristics and surgical implications of an AKA.
Keywords: Adamkiewicz artery; Anatomy; Aortic aneurysm; Great anterior radiculomedullary artery; Thoracoabdominal aneurysm. Abstract Purpose: The artery of Adamkiewicz AKA provides the major blood supply to the anterior thoracolumbar spinal cord and iatrogenic injury or inadequate reconstruction of this vessel during vascular and endovascular surgery can result in postoperative neurological deficit due to spinal cord ischemia.
Publication types Meta-Analysis Systematic Review.The spinal cord relies on 3 main arteries for vascular supply. The anterior spinal artery supplies the anterior two-thirds, and the 2 posterolateral spinal arteries supply the posterior third of the spinal cord.
The anterior spinal artery originates from the 2 vertebral arteries at the level of the foramen magnum. It is supplied by anterior segmental medullary vessels from the aorta, the biggest of which is the artery of Adamkiewicz, also referred to as the arteria radicularis magna or the great anterior radiculomedullary artery.
Here, approximately 8 to 10 segmental either intercostal or lumbar arteries branch off and split into anterior and posterior branches. The posterior branch then divides into 3: the radiculomedullary artery, the muscular branch, and the dorsal somatic branch. The artery of Adamkiewicz arises from the descending aorta. The location of the artery of Adamkiewicz is very important for many surgical procedures since lack of flow to this vessel can cause ischemia to the spinal cord discussed in the Clinical Significance section.
Several surgical subspecialties must consider its location, to include vascular surgery thoracoabdominal aortic aneurysm repairorthopedics thoracolumbar spine surgeryneurosurgery resection of intramedullary tumorsas well as urology and pediatric surgery retroperitoneal dissections. Of note, preoperative imaging may be difficult in patients with bony abnormalities scoliosis, osteophytes, narrowing of intervertebral foramenor patients with extensive arterial disease.
Anterior cord syndrome also called anterior spinal artery syndrome most commonly occurs due to an interrupted supply of the anterior spinal artery or the Artery of Adamkiewicz its major supplierwhich has a less efficient supply compared to the 2 posterolateral spinal arteries. This commonly is caused by atherosclerotic disease, trauma surgical instrumentation or direct injury by a disc or bone fragmenthypotension for example, from blood loss in open surgery like bowel resectionvasculitic disorders.
This syndrome affects the anterior two-thirds of the spinal cord, which includes the majority of the anterior and lateral white matter funiculi, the central gray matter, the bilateral lateral and anterior horns, and the bases of the posterior horns. This results in bilateral loss of motor function flaccid paralysis at level of lesion and spastic paralysis below the lesion from loss of the corticospinal tract and anterior horn, bilateral loss of pain and temperature one level below the lesion from loss of the spinothalamic tract, and sexual dysfunction and urinary and fecal incontinence from loss of descending autonomic tracts.
Successful recovery involves enrolling patients in physical therapy, occupational therapy, and mental health support. Etiologies include arteriovenous malformations and fistulae, as well as isolated spinal artery aneurysms. Spinal subarachnoid hemorrhage should be on the differential diagnosis of patients who present with sudden-onset back pain, myelopathy, and radiculopathy.
Transforaminal epidural steroid injections are commonly used to treat radicular pain, and there have been case reports of spinal cord infarction and acute paraplegia following this procedure.S2000 fast and furious toy
Typically, a posterior approach with a subpedicular technique is utilized. While this method avoids injury to the nerve root, disruption of blood supply to the anterior spinal cord can occur with this procedure in the thoracic or upper lumbar spine if the needle tip is in the vicinity of the AKA, or other anterior medullary arteries.
Case reports have suggested that acute paraplegia was due to direct needle injury, induced vasospasm, or embolization. Thus, it has been proposed that when epidural injections are performed at L3 and above, the needle should be placed in the inferior foramen instead.
