Neuro-oncological surgery challenges
In neuro-oncological surgery, the aim is to perform a maximal safe resection and 75% of patients can be treated with a gross total removal, with 25% of patients suffering new neurological deficit. To achieve this aim and determine the best surgical approach, it is critical to identify the lesion and understand the disease evolution as well as know the relevant structures and relationships with the lesion.
All this information can be leveraged within navigation tools to plan the surgery and elaborate case-specific strategies. Several tools also provide assistance during brain tumor surgery, helping to improve the precision of procedures and perform a rigorous quality check.
Tools for neurosurgery & neuro-oncological surgery
Neurosurgeons have several tools for pre-operative investigations, and in particular imaging techniques: CT-scan, MRI, angiography, ultrasound, transcranial magnetic stimulation, etc. All this information can be integrated through 3D imaging technology, with slices, to obtain one single 3D reference data frame. Then, through segmentation, 3D images can be transposed and become 3D structure objects that can be projected in a 3D environment. It can be through a computer screen display or with new tools, such as a stereoscopic Mixed Reality display.
There is also a wide range of surgical assistance tools. Microscopes provide magnification but also support fluorescence (for example with
