Vascular abnormalities of the spinal cord ]

Vascular anomalies of the spinal cord were studied in 49 patients. Thirty-three cases were morphologically studied (30 cases presented with operative findings and 3 cases with autopsy material). The anomalies presented as defects of vascular genesis without signs of blastomatous growth (venous and capillary-venous malformations, arteriovenous anastomose and fistulas, varicosis of the spinal cord, etc. located in the spinal cord, its roots, coats, adjacent fat, and vertebra which affect the spinal cord, roots or vessels participating in their blood supply and venous outflow. In 41% of the cases, the above anomalies were associated with congenital anomalies of other systems and organs. The anomalies are clinically characterized. Specific signs are given to differentiate them from their intracranial analogues. Recommendations are given on pathological examination of the content of the vertebral canal in vascular anomalies.
