Fluorescein sodium is one of the fluorophores that is used in the resection of intracranial lesions. It is commonly used along with a customized microscope, which is expensive and not available universally. In this study, we describe a simple, inexpensive method for better visualization of intracranial and spinal cord lesions with fluorescein. ⋯ Fluorescein sodium is a safe dye; it can be used to aid in precise localization and safe maximal resection of the pathologic tissue with the help of a blue light source at any center with challenged resources. The blue light enhances the fluorescence and visualization of the pathologic tissue, and this technique can be adopted by any surgeon without much difficulty even with a basic neurosurgical setup.

Endovascular Treatment of Middle Cerebral Artery Dissecting Aneurysms: A 7-Year Single-Center Study.
To evaluate safety and efficacy of endovascular treatment of middle cerebral artery dissecting aneurysms (MCADAs). ⋯ Our data suggest that endovascular treatment of MCADAs appears to be safe and effective. The choice of treatment method needs to be individualized. Larger studies are required to evaluate these promising results.

Acute Compartment Syndrome as a Complication of the Use of Intraoperative Neuromonitoring Needle Electrodes.
The use of intraoperative neurophysiologic monitoring (IOM) has become commonplace in many neurosurgical procedures as a tool to reduce the risk of complications through the early identification of reversible neurologic compromise. Although complications related to IOM itself are exceedingly rare, recognizing their clinical presentation in the postoperative neurosurgical patient is essential for the early identification and implementation of appropriate treatment. ⋯ This case represents the first report of post-procedural compartment syndrome resulting from placement of neuromonitoring needles for routine IOM. Although it is a particularly rare complication of IOM, compartment syndrome represents a surgical emergency that carries significant morbidity if not immediately recognized and treated.

A possible risk factor for premature facet joint degeneration or adjacent segment degeneration after surgical treatment of spine fractures is facet joint violation (FV) during insertion of pedicle screws. The aim of this study was to determine risk factors for FV in the thoracic and lumbar spine after minimally invasive screw insertion or open instrumentation (OI). ⋯ FV is a common complication after thoracic and lumbar spine surgery. Although both, the SL instrumentation and a minimally invasive procedure increases its occurrence, the patient characteristics do not affect the rate of FV.

Cerebral lipiodol embolization is a rare but known complication of lymphatic embolization for plastic bronchitis. The classic imaging finding on a noncontrast head computed tomography is multiple small areas of hyperdensity within the cerebral hemispheres, which represent lipiodol deposition in the brain. We report a case of lipiodol deposition in the middle cerebral artery following lymphatic embolization, producing an "ultradense" vessel sign on noncontrast computed tomography.
