[Peroperative use of two-dimensional ultrasonic imaging in neurosurgery].

The use of "real-time" ultrasonographic two-dimensional picture in the neurosurgery operation theatre increases and improves the possibility of localization of intracerebral and intraspinal lesions, enables precise needle biopsies, decreases a potential risk of damage to healthy brain tissue, visualizes the results of tumour resection, helps in the localization of catheters into chambers and cysts. The final results of the application of two-dimensional picture in the course of neurosurgery operation is in speeding up the surgical therapy, giving it more precision and safety, while the prolongation of the operation due to the ultrasonography is negligible. The authors document the visualization possibilities of two-dimensional ultrasonographic scanning with linear probe in preoperational recordings of different types of lesions in intracranial and intraspinal space.
