Spinal Cord Blood supply

The spinal cord is supplied with blood by three arteries that run along its length starting in the brain, and many
arteries that approach it through the sides of the spinal column. The three longitudinal arteries are called
the anterior spinal artery, and the right and left posterior spinal arteries.[2] These travel in the subarachnoid space
and send branches into the spinal cord. They form anastamoses (connections) via the anterior and
posterior segmental medullary arteries, which enter the spinal cord at various points along its length.[2] The actual
blood flow caudally through these arteries, derived from the posterior cerebral circulation, is inadequate to maintain
the spinal cord beyond the cervical segments.


The major contribution to the arterial blood supply of the spinal cord below the cervical region comes from the
radially arranged posterior and anterior radicular arteries, which run into the spinal cord alongside the dorsal and
ventral nerve roots, but with one exception do not connect directly with any of the three longitudinal
arteries.[2] These intercostal and lumbar radicular arteries arise from the aorta, provide major anastomoses and
supplement the blood flow to the spinal cord. In humans the largest of the anterior radicular arteries is known as
the artery of Adamkiewicz, or anterior radicularis magna (ARM) artery, which usually arises between L1 and L2,
but can arise anywhere from T9 to L5. [3] Impaired blood flow through these critical radicular arteries, especially
during surgical procedures that involve abrupt disruption of blood flow through the aorta for example during aortic
aneursym repair, can result in spinal cord infarction and paraplegia.

Description: Dr Alan Moelleken MD, Moelleken, Expert witness, anti-trust, lawsuits, cottage hospital, spine, orthopedic, various medical terms for educational inquiry purposes only. Not a final determination of medical or legal terms.
About Board Certified and Fellowship Trained Orthopedic Surgeon Specializing in Surgeries of the Spine Dr. Moelleken attended SUNY Albany as an undergraduate student. He graduated number one in his class with a Double Honors’ Degree and was inducted into Phi Beta Kappa as a junior. He subsequently enrolled in the University of Pennsylvania School of Medicine in Philadelphia, where he received his medical training and graduated with an M. D. degree in 1983. He then preformed a year of orthopedic surgery research at the University of Pennsylvania School of Medicine. He was then accepted into a prestigious orthopedic residency program at the University of California at Los Angeles (UCLA). After completion of his residency, he attended New York University (NYU), New York, for special fellowship training in neurosurgery and orthopedic spine surgery. His mentors included some of the most famous neurosurgeons, spine surgeons, and experts in scoliosis. While at NYU, he served as an assistant professor and an attending physician teaching neurosurgery and orthopedic residents at Bellevue Hospital Medical Center in New York and at the Department of Veterans’ Affairs Medical Center in New York (affiliated with NYU Medical Center). Dr. Moelleken is a member of a variety of academic and scientific organizations, such as the American Association of Orthopedic Surgeons (AAOS), the North American Spine Society (NASS), and the American Medical Association (AMA). He has authored numerous scientific publications and presentations. For the past nine years, he has been the chairman of the monthly Tri-County Spine Conference. He maintains his cutting-edge knowledge and expertise as a spine surgeon by regularly attending national and international spine conferences and by constantly familiarizing himself with the latest research in the fields of orthopedic surgery and neurosurgery, especially as it pertains to disorders of the spine.
