Microangiographic Studies on Cervical Cord Injuries

概要

Spinal microangiography was performed at autopsy examinations on 6 dead cases of cervical cord injuries. The anterior radicular arteries, anterior spinal artery and vasa corona were well visualized. The penetrating branches of the pial arterial plexus or vasa corona were not demonstrated in some areas surrounding the injured site correspondingly to the degree of injury.Extravasations of the contrast media at the lesioned site can be experimentally observed soon after suffering the lesion. But in one case died 6 days after suffering, no figures of extravasation were obtained because the contrast media could not be filled due to the necrosis brought about in the destructed blood vessel. In the acute phase, vasomotor paralysis was seen and markedly edematous sites were very difficult to be present on microangiogram. In so far known cases, injured sites of the spinal cord and hemorrhagic necrosis and edematous necrosis were no visualized on microangiogram.
