Identification Of Vascular Anomalies
Once reported as the only roentgenographic method consistently demonstrating vascular anomalies of the spinal cord, myelography is an adjunct to a new Mayo Clinic procedure.In a series of 13 cases studied since 1963, angiographic methods successfully opacified and differentially identified vascular anomalies of the spinal cord in 11 patients. The senior investigator, H. L. Baker, Jr., MD, told members of the Radiological Society of North America that in all of the 13 cases, positive contrast myelography preceded and led to angiography.Subsequent analysis of the films revealed three distinct angiographic patterns. "The recognition and differentiation of these patterns is important not only because it offers insight with regard to therapy and prognosis," said Dr. Baker, "but may suggest the presence of a tumor which would contraindicate ligation of the feeding vessels at a point remote from the spinal canal."
