The Valvular Action of the Arnold-Chiari Malformation

  • B. Williams

Abstract

Hernias within the craniospinal axis, as elsewhere, are caused by pressure differences. When such a hernia is tightly impacted there are pressure gradients across it, but during its development such pressure differences may be temporary. The Arnold-Chiari Malformation (ACM) is a herniation of the hind brain, downwards through the foramen magnum, which is moulded to form a close fitting plug with a potentially valve like action. The effects of pulsation upon this and on lesser degrees of cerebellar herniation are of interest.
