Case ReportsA role of diffusion tensor imaging in movement disorder surgery.
The safe and reversible nature of deep brain stimulation (DBS) has allowed movement disorder neurosurgery to become commonplace throughout the world. Fundamental understanding of individual patient's anatomy is critical for optimizing the effects and side effects of DBS surgery. Three patients undergoing stereotactic surgery for movement disorders, at the institution's intraoperative magnetic resonance imaging operating suite, were studied with fiber tractography. ⋯ This represents a possible mechanism of the increased effects and side effects observed with higher stimulation voltages. Currently available diffusion tensor imaging techniques allow potential methods to characterize the effects and side effects of DBS. This technology has the potential of being a powerful tool to optimize DBS neurosurgery.

The effect of lung-protective permissive hypercapnia in intracerebral pressure in patients with subarachnoid haemorrhage and ARDS. A retrospective study.
Lung protective ventilation has a beneficial effect in treating patients with acute respiratory distress syndrome (ARDS). An effect of this ventilation modality is hypercapnia, which leads to increased cerebral blood flow. Since increased cerebral blood flow can induce brain oedema the question arises whether lung protective ventilation can be applied in patients with subarachnoid haemorrhage. ⋯ Patients with higher Hunt and Hess grades of subarachnoid haemorrhage who are predominantly intubated and ventilated and most of them suffer from ARDS can receive lung protective ventilation. In our small patient collective, the occurring hypercapnia did not influence (increase) the intracerebral pressure.
