Pathomorphological and Pathophysiological Aspects
Considering the practical experience with spinal angiography, doubts as to the validity of the “partial flow theory” (Adamkiewicz, 1882), are no longer reasonable. Variability in vessel caliber of the ascending and descending branches of the anterior radicular arteries, however, demonstrates that the hemodynamics of these circulatory partial systems cannot be strictly classified, and that the proportions of blood running cranially or caudally vary.
