  • Title: The intrinsic vasculature of the lumbosacral spinal nerve roots.
    Author: Parke WW, Watanabe R.
    Journal: Spine (Phila Pa 1976); 1985; 10(6):508-15. PubMed ID: 4081865.
    Abstract:
    The observations made in this study strongly support the concept that spinal nerve roots in general and the human lumbosacral spinal nerve roots in particular are structurally, vascularly, and metabolically unique regions of the nervous system. Peculiarities of their intrinsic vasculature and supporting connective tissue may account for suspected "neuroischemic" responses to pathologic mechanical stresses and inflammatory conditions associated with degenerative disease of the lower spine. It is hoped that the newly described features of the radicular vasa nervorum (to avoid confusion with the dissimilar blood supply of peripheral nerves, the term "vasa radiculorum" might be more accurate) may advance the understanding of certain aspects of lower spine symptomatology and provide some basis for much needed future research.
