Stratification of intraoperative ischemic impact by somatosensory evoked potential monitoring, diffusion-weighted imaging and magnetic resonance angiography in carotid endarterectomy with routine shunt use.
Routine shunting to minimize ischemia during carotid endarterectomy (CEA) is controversial. The aim of this study was to stratify the ischemic parameters associated with CEA and evaluate the effect of routine shunting in attempting to mitigate those ischemia. ⋯ SSEP<50%, >5 min, new DWI lesions, and MRA asymmetry were able to stratify the ischemic impacts in CEA. Meticulous routine shunting could mitigate those appropriately.

Attitudes of young neurosurgeons and neurosurgical residents towards euthanasia and physician-assisted suicide.
Euthanasia and physician assisted suicide (PAS) are two controversial topics in neurosurgical practice. Personal attitudes and opinions on these important issues may vary between professionals, and may also depend on their location since current legislation differs between European countries. As these issues may have significant impact on clinical practice, the goal of the present study was to survey the opinions of neurosurgical residents and young neurosurgeons across Europe with respect to euthanasia and physician assisted suicide. ⋯ The results of this first survey on neurosurgical residents' attitudes towards euthanasia and PAS show that a significant number of residents is not familiar with national and/or local regulations regarding euthanasia and PAS. If legally allowed, most residents would be in favor of euthanasia and PAS, but only a minority would be willing to actively participate in these practices. We did not observe a difference in stances on euthanasia and PAS among residents from different regions in Europe.

Falcine venous plexus within the falx cerebri: anatomical and scanning electron microscopic findings and clinical significance.
Only limited attention has been paid to the anatomy and clinical importance of the falcine venous plexus. The aim of this study was to evaluate the falcine venous plexus anatomically using scanning electron microscopy (SEM), and to provide guidance for neurosurgical approaches. ⋯ The falcine venous plexus is a network of venous channels that exists within the connective tissue of the falx; the sizes and patterns of communication of these structures showed regional differences. Neurosurgeons should be aware of the regional differences when making an incision or puncturing the falx during a surgical approach.

Comparison of functional and histological outcomes after intralesional, intracisternal, and intravenous transplantation of human bone marrow-derived mesenchymal stromal cells in a rat model of spinal cord injury.
Few studies have compared methods of stem cell transplantation. The aim of the present study was to determine the optimal method of delivery of therapeutic stem cells in spinal cord injury (SCI). We compared functional and histologic outcomes after administration of human bone marrow stromal cells (BMSCs) by intralesional (ILT), intracisternal (ICT), and intravenous transplantation (IVT). ⋯ ICT may be the safest and most effective method for delivering stem cells and improving functional outcome in SCI when no limits are placed on the number of cells transplanted. As research on enhancing engraftment rates advances, further improvement of functional outcome can be expected.
