The Difference Between Ultrasound-Guided and Sterotactic_Guided Neurosurgical Procedures

We evaluate two different methods, ultrasound (US) guidance and sterotactic guidance, routinely used in our Department for navigation in various neurosurgical procedures. We have performed 53 US-guided and 101 sterotactic-guided procedures. These procedures were intracranial lesion biopsies, intracranial cysts and abscesses puncture and evacuations, ventricular punctures for hydrocephalus shunt operations, sterotactic-guided microneurosurgical resections and sterotactic-guided endoscopic operations. Advantage of the US-guided operations are the shortness of the procedure, simplicity (no need for moving patient for additional CT scanning), no irradiation and the possibility of real time imaging. The disadvantages of the US-guided procedures are worse resolution of the images in deep-seated and small lesions as well as the need for bigger trepanation because of the transducers dimensions. Sterotactic procedures are time- consuming but more precise and usually done in local anaesthesia because only a small trepanation is required.Main disadvantage of the sterotactic-guided procedures when compared with the US-guided procedures is a lack of real-time intraoperative control.
