Clinical TrialVisualization of the pyramidal tract in glioma surgery by integrating diffusion tensor imaging in functional neuronavigation.
The aim of this study was to investigate whether diffusion tensor imaging (DTI) can be integrated into functional navigation for the intraoperative visualization of the pyramidal tract. ⋯ DTI can be reliably integrated into navigational datasets. Thus, microscope-based neuronavigation can be used for an intraoperative visualization of the course of the pyramidal tract. However, a possible shifting of the pyramidal tract has to be taken into account after major tumor parts are removed.

Case ReportsThe use of neuronavigation in transnasal transsphenoidal pituitary surgery.
Recurrent pituitary adenomas and localisation of microadenomas potentially cause difficulties during transsphenoidal pituitary surgery. Neuronavigation might improve tumour removal in such cases. ⋯ Neuronavigation in pituitary surgery is of use in only a small number of cases. Nevertheless, we suggest that contour-guided, transsphenoidal adenomectomy may prove helpful in approaching recurrent adenomas and localising lateral microadenomas.

Neurological and psychosocial outcome after subarachnoid haemorrhage, and the hunt and hess scale as a predictor of clinical outcome.
In a retrospective study, the outcome of 87 patients with ruptured intracranial aneurysm was assessed. Follow-up included neurological examination, grading of the Glasgow Outcome Scale (GOS) of each patient, and answering a psycho-social questionnaire. This questionnaire was answered by the patients themselves or by a relative when the patient was not able to answer. ⋯ Significant correlations were found between the initial Hunt and Hess grade and the initial Fisher grade, between neurological deficits and GOS, between quality of life and occupational outcome, as well as between the GOS and quality of life assessment, but not between initial Hunt and Hess grade and GOS or quality of life, between neurological deficits and quality of life, between initial Hunt and Hess grade and occupational outcome, between initial Fisher grade and occupational outcome, and also not between initial Fisher grade and GOS or quality of life. Our results suggest that neither the initial Hunt & Hess grade nor the initial Fisher grade are suitable parameters for predicting the outcome of patients with ruptured intracranial aneurysms. The fact that GOS and quality of life correlated significantly confirms the use of GOS as a simple method for evaluating patient outcome, although it is not a grading system for evaluating functional disorders such as memory or subtle cognitive impairments.
