Academic metrics can be used to compare the productivity of researchers. We aimed to use a variety of bibliometric parameters to assess the productivity of neurosurgeons working in the United Kingdom. ⋯ This study details the academic impact of United Kingdom-based neurosurgeons through the analysis of a number of citation metrics. It provides a benchmark bibliometric profile and we advocate future comparative assessments as a means to assess impact of and guide academic policy.

Case Reports
Delayed deterioration in isolated traumatic subarachnoid hemorrhage Report of two cases.
Isolated traumatic subarachnoid hemorrhage (SAH) in association with mild traumatic brain injury is considered to be a less severe finding that is not likely to require surgical intervention. No previous reports have described cases warranting craniotomy for isolated traumatic SAH by itself. ⋯ Isolated traumatic SAH seen in the basal cistern and Sylvian fissure carries a risk of late deterioration. A possible cause of hematoma expansion is abruption of a perforating branch arising from the MCA at the time of head injury. When hematoma expansion is identified, surgical evacuation of the hematoma is indicated. Surgical evacuation should be safely performed with the knowledge of the point of bleeding in such patients.

Reporting the outcome of two patients who underwent unilateral ablative stereotactic surgery to treat pharmacologic resistant posttraumatic tremor (PTT). ⋯ Radiofrequency lesion of the cZi/VOP target was effective for posttraumatic tremor in both cases. The use of T2-weighted images and MER was found helpful in increasing the precision and safety of the procedure, because it leads the RF probe by relying on neighbor structures based on thalamus and subthalamic nucleus.

Deep brain stimulation (DBS) of the anterior cingulate cortex (ACC) is a new treatment for alleviating intractable neuropathic pain. However, it fails to help some patients. The large size of the ACC and the intersubject variability make it difficult to determine the optimal site to position DBS electrodes. The aim of this work was therefore to compare the ACC connectivity of patients with successful versus unsuccessful DBS outcomes to help guide future electrode placement. ⋯ These findings could help improve presurgical planning by optimizing electrode placement, to selectively target the tracts that help to relieve patients' pain and to avoid those leading to unwanted effects.
