Abstract		Background. Neuronavigational system is a computerised system for intraoperative planning and guidance of neurosurgical procedures using interactive image presentation. The application of such system is denoted as neuronavigation. There are many neuronavigational systems with different technical solutions for intraoperative guidance. Methods. From June 2002 till April 2003 fourteen patients (mean age 52 years) were operated using of neuronavigational system on department of neurosurgery in Maribor General Hospital. We used neuronavigational system based on infrared light detection and intraoperative guidance with the help CT imaging in three planes. Results. The system was used in four cases of biopsy, four cases of lesion reduction and six cases of total lesion removal. 11 brain lesion were situated subcorticaly or deeper, two were cortical and one was osteolitic lesion of the skull bone. Lesions mean diameter was 3.5 cm. Calculated accuracy of interactive image guidance was good in all 24 cases. Conclusions. Neuronavigational system which we used is simple and quite accurate. Its usage improves speed, safety and accuracy of most neurosurgical procedures.
Summary		Izhodišča. Nevronavigacijski sistem je računalniško podprt sistem za medoperativno načrtovanje in vodenje nevrokirurških postopkov z interaktivnim slikovnim prikazom. Številni nevronavigacijski sistemi uporabljajo različne tehnične rešitve za medoperativno sprem janje. Uporabo takega sistema imenujemo nevronavigacija. Metode. Od junija 2002 do aprila 2003 smo na Oddelku za nevrokirurgijo Splošne bolnišnice Maribor z nevronavigacijo operirali 14 bolnikov (povprečna starost 52 let). Uporabjali smo nevronavigacijski sistem, ki temelji na zaznavanju infrardečih odbojev in medoperativnem sprem janju spomočjo računalniškotomografskega slikovnega prikaza v treh ravninah. Rezultati. Nevronavigacijski sistem smo uporabili v štirih primerih biopsije, štirih primerih redukcije spremembe ter v šestih primerih popolne odstranitve spremembe. 11 možganskih sprememb je ležalo subkortikalno ali globlje, dve sta bili kortikalni možganski spremembi, ena pa osteolitična sprememba v možganski kosti. Povprečni premer je znašal 3,5 cm. Izračunana natančnost interaktivnega slikovnega prikaza je bila dobra pri vseh 14 bolnikih. Zaključki. Nevronavigacijski sistem, ki ga uporabljamo, je enostaven in dokaj natančen. Poveča hitrost, varnost in zanesljivost pri večini posegov na možganih.
