The author relates a G. Pisani and T. Conti experimental publication achieved on alive animals. This Errichiello’s paper comments about literature on anatomic features of intramedullary spinal arteries, and argues about question if they are terminal or anastomotic. It relates the anatomic descriptions on traditional literature. Principal results say that majority of experts observe that haematic circulation in spinal medulla is of terminal type. Similarly recent papers describes intramedullary arteries not anastomotic and therefore the nervous medullary parenchyma is particulary affected by ischaemic damage. Conversely, experimental Pisani and Conti’s work, achieved with in vivo coloration method on anaesthetized animals, attest on histological preparations a wide anastomotic net inside spinal cord; in this way it responds to the question why myelomalacicis post-traumatic ischaemic damages not appear after each rachis offending event.
