I.はじめに
脊髄動静脈奇形(以下spinal AVM)のうち,動静脈短絡部が硬膜内ではなく,硬膜表面にあり,灌流静脈が脊髄表面を走行するAVMが新たなtypeとして最近注目されるようになってきた4,6,8,10).われわれは過去15例のspinal AVMを経験したが,血管撮影上の所見より3例が硬膜AVMともいうべきこのようなタイプと考えられたので,文献的考察を加えて報告する.
A new type of spinal AVM is reported. The chracteristics are as follows : 1) All the patients are male over 50-years-old.
2) Their symptoms are insiduous and progressive ischemic pattern.
3) All the lesions locate at the thoracic and lumbar levels.
4) Selective intercostal angiography shows a fistulous AVM adjacent to the intervertebral foramen fed by spinal chiral branch and drain into tortuous veins on the spinal cord via radiculomedullary vein. No typical hair-pin configuration by radiculo- medullary and spinal cord arteries contributes to the AVM.
