Review[Use of transcranial Doppler ultrasonography for evaluation of intracranial pressure].
Transcranial Doppler (TCD) studies are very useful for the evaluation of intracranial pressure changes. The most informative for the TCD increase diagnosis are the diastolic pressure decrease and increase of two computed indices: pulsatility index (PI) and resistance index (RI). ⋯ Additional information is provided by TCD studies in cerebral blood flow autoregulation tests. The usefulness of TCD in brain death diagnosis is discussed also.

Case Reports[Cranial bone prosthesis made of acrylic resins and prepared before surgical operation--description of the method].
The authors present a method of cranioplasty using super-acrylate type "O". Two approaches are used to this problem--copying of the own bone of the patient and use of an appropriate prosthesis made of plastic material used in maxillofacial surgery. The obtained results were favourable with respect to cosmetic effect and clinical outcome.

Subarachnoid haemorrhage from an intracranial aneurysm or arteriovenous malformation is a grave complication of pregnancy. The authors analyzed 11 cases of verified subarachnoid haemorrhage during pregnancy from 10 identified and 1 unidentified cerebral vascular malformation. The aneurysms were responsible for subarachnoid haemorrhage in 6, and arteriovenous malformation in 4 patients. We conclude that the decision to operate after subarachnoid haemorrhage during pregnancy should be based upon neurosurgical principles, whereas cesarean delivery should be done in every pregnant patient with subarachnoid haemorrhage.
