Abstract
Neuronavigation has become an established technology which provides objective data for localization in 3D space and thus decreases uncertainties regarding tumor localization, relation to vasculature, safe trajectories, and craniotomy design during surgery. We have evaluated whether neuronavigation based purely on 3D ultrasound without any preoperative navigational imaging can provide necessary information for navigation and resection control. This application is a new way of utilizing ultrasound-guided neuronavigation. Eighteen patients were operated on with ultrasound-based navigation only; they represented 16% of all the 131 navigation-assisted procedures during our 1-year study period. Of the procedures, 2 were planned as diagnostic biopsies, 1 was resection of an abscess, and 15 were tumor resections. Pre- and postoperative radiological images were evaluated to assess volumes and volume reduction following surgery. Pathology results were recorded. For patients undergoing resections, the resection radicality was >99% in 12 patients and 95–99% in 4 patients undergoing resections. In the latter patients, additional radicality was avoided intentionally because of concern for sensitive central structures. The two biopsies yielded representative material. It was possible to use operative neuronavigation based on intraoperative ultrasound without relying on preoperative navigational imaging. Neuronavigation based solely on intraoperative ultrasound was feasible and may increase surgical safety when preoperative neuronavigational image is not feasible or unavailable.

Intraoperative imaging has become almost mandatory, but the preferred method by intraoperative MRI is impossible for all cranial cases and extremely time consuming and expensive. Intraoperative ultrasound technology has low initial costs and basically no maintenance costs, and neuronavigation has become a state-of-the-art tool nowadays.
We mentioned earlier that especially in economically challenging countries, such a combination of navigation with ultrasound can be the broad intraoperative imaging solution. Nevertheless, the user needs to get used and trained to interpret US images. This, in fact, is one of the key problems for neurosurgical US users. Even as a frequent US user, one has only 50 cases per year! A cardiologist or radiologist has this case load in a week or two. Our US experience is therefore low but could gain significantly if US was used more often and probably more sophisticated. The absolute advantage of navigated intraoperative 3D ultrasound (without MRI) is the better orientation through display in familiar planes (axial, coronal, and sagittal) compared to just US, and we demonstrated this (as other groups) in different settings as well (with different navigation or ultrasound companies). In my view, intraoperative US can never completely substitute intraoperative MRI, but in easy cases, like metastases, cavernomas, or hemangiomas, intraoperative US is absolutely enough for resection control. Recently, my prior colleagues have presented the same idea in a smaller setting in this journal as well [1]. I congratulate the authors for another valuable presentation of the use of this navigated 3D US in a stand-alone setting.

Ultrasonography provides real-time imaging without a radiation burden to the patient. Intraoperative ultrasonography does not entail any special requirements on the neurosurgical armamentarium or the environment of the operating theater. Ultrasonographic devices are significantly cheaper than iCT and especially iMR. Intraoperative ultrasonography has been successfully integrated into neuronavigation systems, providing the potential for brain shift evaluation and correction.
In their paper, Peredo-Harvey and colleagues presented 18 patients who unintentionally underwent purely 3D ultrasound-based neuronavigational procedures without any preoperative navigational imaging, due to technical problems in loading MR images into the navigation device or to the urgency of the procedures, which did not allow additional time for immediate preoperative imaging. The procedures included 15 tumor resections, 2 biopsies, and 1 abscess resection. In the series, navigation based entirely on intraoperative ultrasound images allowed satisfactory delineation of lesions and complete performance of surgical intentions in all 18 patients. The intraoperative interpretation of ultrasound images correlated well with postoperative radiological imaging.
As mentioned in the text, neuronavigation based purely on intraoperative ultrasound imaging without preoperative neuronavigational planning is a reliable and useful technique which could be helpful especially in emergency procedures and when technical problems make preoperative images inaccessible. Obviously, the main disadvantage of the technique is the non-navigational planning of craniotomy, which could be a source of inaccuracy.
In conclusion, in my opinion, neuronavigation based purely on intraoperative ultrasound imaging without preoperative neuronavigational planning represents reliable, safe and cost-effective, alternative neuronavigational technique.
