Two dimensional echoencephalography during the neurosurgical operations

The authors describe the use of two dimensional ultrasonic image in time of neurosurgical operations. After craniotomy it is possible by means of B-scan to localise the brain pathology, to measure its depth from the brain surface as well as to plan the surgical strategy. The safety of this examination, its simplicity and immediate working results are stressed. This examination is recommended for all operations in intracranial space, because it enables the best possible orientation of the surgeon.
