[Pathology of the cerebrospinal fluid tract after subarachnoid hemorrhages (the x-ray and radiological aspect)].

The authors examined the semiotics of hydrocephalus occurring after subarachnoidal hemorrhages (SAH) from arterial aneurysms and arteriovenous malformations to provide pathogenetic evidence for surgical or conservative hydrocephalus. The spinal fluid tract was examined in 44 patients after SAH by computed tomography and radionuclide cysternomyelography using 99mTc. Variability was found in the radiological semiotics of open internal hydrocephalus. Radiological studies revealed frequently open internal hydrocephalus in patients with arterial aneurysms and arteriovenous malformations without subarachnoidal hemorrhages. The radiological semiotics of open hydrocephalus after SAH determines both morphological changes of the spinal fluid tract and liquorodynamic disturbances.
