Sodium- Fluorescein as intraoperative visualization tool during peripheral nerve biopsies.
Owing to technical development of specific fluorophore filters, the neurosurgical application of sodium fluorescein (SF) has regained value in brain tumor surgery. The aim of this study was to determine the usefulness of SF during nerve biopsies. ⋯ Magnetic resonance imaging is the gold standard in diagnostic work-up of peripheral nerve disorders. Longitudinal nerve thickening with positive contrast enhancement is an unspecific magnetic resonance imaging finding. Various pathologies, such as tumors and inflammatory lesions, may cause this morphologic phenomenon. Nerve biopsies may be needed for diagnostic work-up. Intraoperative SF may help to depict the most affected fascicles and identify target fascicles for biopsy and increase diagnostic certainty of nerve biopsies.

Subclavian steal phenomenon can cause retrograde flow in the vertebral artery as a result of ipsilateral occlusion of the subclavian artery. This phenomenon has various clinical presentations, such as claudication of the affected extremity or intermittent vertebrobasilar ischemia. Aneurysm formation in the spinal cord circulation is exceptionally rare but may occur secondary to collateral formation in subclavian steal syndrome. ⋯ After endovascular coiling of the aneurysm, the patient had no neurologic deficits or postoperative complications. Postoperative angiography revealed complete obliteration with no residual aneurysm. Imaging further demonstrated patency of the radiculomedullary (anterior spinal) artery.

To investigate the extent to which restraint is used in neurosurgical care, under what circumstances, and how it is documented. ⋯ Restraint in neurosurgical care is mostly used to prevent patients from harming themselves or others. Because of the lack of documentation, restraint measures cannot be openly assessed, thus putting patients' safety at risk.

Selection of appropriate treatment for patients with recurrent brain metastasis (BM) remains uncertain. Recent studies have demonstrated a significant response rate and acceptable toxicity using fractionated stereotactic radiosurgery (FSRS) in patients with locally recurrent large BM. The aim of this study was to evaluate efficacy and toxicity of FSRS with bevacizumab as a new salvage treatment for locally recurrent BM with previous high-dose irradiation. ⋯ FSRS with adjuvant bevacizumab treatment showed favorable clinical and radiologic control as a salvage treatment regimen. The diagnoses of radiation necrosis and local recurrence after salvage FSRS warrant further study.

Preoperative malnutrition is associated with increased postoperative complication rate and hospital length of stay. However, the degree to which these risks can be mitigated by nutritional consultation has not been well described. To address this, we sought to determine if a preoperative nutrition consult was associated with decreased 30-day complication rate and hospital length of stay. ⋯ On multivariable analysis, receipt of a preoperative nutrition consult was associated with both decreased 30-day complication rate and shorter hospitalization. We therefore posit that greater implementation of nutritional counseling may help to decrease complication rates and expedite discharge in patients undergoing surgical intervention for spinal metastases.
