[Cerebellar complications following operations in the spinal region].

A report is given on three patients in whom after interventions in the region of the vertebral column and the spinal cord haemorrhages in the area of the posterior cranial fossa had occurred. An excart diagnosis is only possible by exact neurological findings and computer tomography. The causes of these complications are discussed, therapeutically there is only the restoration of the cerebrospinal fluid passages through the efferent systems.
