Description:
Test to determine whether or not the flow of cerebrospinal fluid is blocked in the spinal canal. The test is performed by putting bilateral pressure on the jugular veins - vv. jugulares internae - during the course of a lumbar puncture. Normally there is a sharp rise increase in the pressure of the spinal fluid in the lumbar region within 10 to 12 seconds, and then a sharp fall when the pressure is released.
If there is no rise in the pressure of liquor cerebrospinalis, it is a sign of blocking of the subarachnoid channels.
Queckenstedt's phenomenon was described by the British surgeon and anatomist John Hilton (1804-1878) in 1863 on the basis of investigation of a corpse.
