In Situ M2 Bypass for Treatment of Fusiform Middle Cerebral Artery Bifurcation Aneurysm: Technical Case Instruction and Operative Video.

Background And Importance: Fusiform middle cerebral artery (MCA) bifurcation aneurysms can be challenging to treat with standard endovascular or microsurgical techniques. The in situ side-to-side bypass technique represents an elegant revascularization option for these aneurysms when trapping becomes necessary.

Clinical Presentation: A man in his 50s presented for evaluation of an incidentally found fusiform, 10 mm, right MCA bifurcation aneurysm with involvement of both the inferior and superior M2 trunks.

Fully Endoscopic Microvascular Decompression of the Trochlear Nerve for Treatment of Medically Refractory Superior Oblique Myokymia: Technical Case Instruction and Operative Video.

Background And Importance: We describe, to our knowledge, the first report of fully endoscopic microvascular decompression (MVD) of the trochlear nerve in a patient with superior oblique myokymia (SOM).

Clinical Presentation: A 51-year-old female presented with multiple years of intermittent, "jumpy," and "shimmering" visual disturbances. She was diagnosed with SOM.

Return of intracranial beta oscillations and traveling waves with recovery from traumatic brain injury.

Traumatic brain injury (TBI) remains a pervasive clinical problem associated with significant morbidity and mortality. However, TBI remains clinically and biophysically ill-defined, and prognosis remains difficult even with the standardization of clinical guidelines and advent of multimodality monitoring. Here we leverage a unique data set from TBI patients implanted with either intracranial strip electrodes during craniotomy or quad-lumen intracranial bolts with depth electrodes as part of routine clinical practice.

Endoscopic Microvascular Decompression.

Microvascular decompression is a widely accepted surgical treatment for compressive cranial nerve pathologies such as trigeminal neuralgia, hemifacial spasm, glossopharyngeal neuralgia, and other craniofacial pain syndromes. Endoscopy has risen as a safe and effective minimally invasive tool to optimize microvascular decompression. Endoscopy offers improved visualization, minimizes retraction, and allows for smaller surgical openings compared to traditional microscopic approaches.

Fluorophores in Endoscopic Neurosurgery.

The complexity of intracranial anatomy and pathologies warrants the optimization of multimodal techniques to ensure safe and effective surgical treatment. Endoscopy is being more widely implemented in intracranial procedures as an important visualization tool, as it can offer panoramic views of deep structures while reducing the invasiveness of approaches. Fluorophores are frequently utilized to augment the identification of intracranial anatomic landmarks and pathologies.
