“…This can be done using a stereotactic frame (Kelly, 1986), or with frameless registration systems (Zamorano et al, 1992;Zinreich et al, 1993;Grimson et al, 1996). Af-(CSF) leakage cause a gravitational shift that is due to the disappearance of tension and pressure forces at the brain and ventricular boundaries (Bucholz et al, 1997;Hill et al, 1998;Maurer et al, 1998;Nabavi et al, 2001). Tissue retraction places brain tissue under constraint, while tissue resection consists of removing tissue, and both cause deformations of neighboring brain tissue (Roberts et al, 1998;Nabavi et al, 2001;Miga et al, 2001).…”

Abstract. The problem of providing surgical navigation using image overlays on the operative scene can be split into four main tasks -calibration of the optical system; registration of preoperative images to the patient; tracking of the display system and patient and display using a suitable visualisation scheme. To achieve a convincing result in the magnified view through the operating microscope high alignment accuracy is required. We have simulated our entire system to establish the major sources of error. We have improved each of the stages involved. The microscope calibration process has been automated. We have introduced bone-implanted markers for registration and incorporated a locking acrylic dental stent (LADS) for patient tracking and/or registration. These improvements have significantly increased the alignment accuracy of our overlays. LADS repositioning on volunteers showed a mean target registration error of 0.7mm. Phantom accuracy is 0.3-0.5mm and clinical overlay errors were 0.5-1.0mm on the bone fiducials and 0.5-4mm on target structures. We have improved the graphical representation of the stereo overlays. The resulting system provides 3D surgical navigation for microscope-assisted guided interventions (MAGI).

“…NN system, although valuable for bone flap positioning and to calculate the surgical trajectory, has a decreased precision after dural opening due to brain shift [12,13], in particular after entering the lateral ventricle and after cerebrospinal fluid escapes in cases with concomitant hydrocephalus, and tissue manipulation.…”

Purpose To assess the usefulness of intraoperative Ultrasound (ioUS) and Echo-Color-Doppler (ECD) for the surgical removal of a specific deep-sited lesion. Methods Case report of a woman underwent surgery of a third ventricle colloid cystremoval. Results The ioUS technique depicted the deep intraventricular lesion and all theanatomical structures surrounding the lesion; helping us defining the best trajectory forthe safest surgical removal. Conclusion In our experience ioUS and ECD have demonstrated to be a reliable anduseful intraoperative tool in neurosurgery, not only for superficial tumors but for deepintraventicular lesions as well.Riassunto Obiettivi Lo scopo di questo articolo è quello di mostrare l'utilizzo dell'ecografia intra operatoria, in B-mode ed EcoColor-Doppler, durante un intervento di asportazione di lesione situata profondamente nelle strutture endocraniche cerebrali.Materiali e Metodi Descrizione di un caso clinico di asportazione chirurgica di una cisti colloide del terzo ventricolo per via trans-ventricolare frontale destra. Risultati L'imaging ecografico intraoperatorio ha permesso di evidenziare e riconoscere precisamente la lesione endoventricolare e tutte le strutture circostanti, seppur situate profondamente, permettendo in tal modo durante l'intervento di assicurare la definizione del miglior approccio chirurgico per una asportazione completa e anatomicamente sicura. Conclusioni In base alla nostra esperienza la tecnica ecografica si è dimostrate affidabile e sicura, durante le procedure neurochirurgiche di asportazione lesionale, non solo per le patologie superficiali (corticali/sottocorticali), ma anche nei casi di lesioni profonde e nel riconoscimento di strutture vitali.

Abstract: These results suggest that intraoperative brain deformation is an important source of error that needs to be considered when using surgical navigation systems.
