Randomized Controlled Trial Comparative Study
Effects of preoperative simulation on minimally invasive Hybrid Lumbar Interbody Fusion (MIS-HLIF).
The main focus of this study was to evaluate how preoperative simulation affects the surgical work flow, radiation exposure, and outcome of minimally invasive hybrid lumbar interbody fusion (MIS-HLIF). ⋯ Preoperative simulation reduced radiation exposure and resulted in less back pain at the 6 months follow-up time point. Preoperative simulation provided guidance in determining the correct cage height. Outcome controls enabled the surgeon to improve the procedure and the software algorithm.

Since the introduction of Gugliemi detachable coils in the early 1990s, major clinical studies have supported an increasing role for coil embolization of ruptured aneurysms. We assessed aneurysm location and treatment modality in aneurysmal subarachnoid hemorrhage (aSAH) over the past 25 years. ⋯ Endovascular treatment of ruptured intracranial aneurysms has steadily increased over the past 25 years at our major academic institution. This is consistent with positive data from clinical trials, advances in endovascular technology, and increasing experience of endovascular specialists.

Foramen magnum meningiomas represent a challenge for neurosurgeons. These tumors require careful surgical manipulation as they are often located in proximity to critical neurovascular structures and the cranial nerves. The far lateral approach is considered the safest neurosurgical approach for excising foramen magnum lesions. ⋯ We describe key historical, epidemiological, genetic, epigenetic, clinical, and neurosurgical aspects of foramen magnum meningiomas. We emphasize the far lateral approach for lesions arising in the foramen magnum, as well as the most appropriate patient positioning for such approach. Caring for these aspects will be rewarded with the best perioperative neurosurgical outcomes.

To observe the clinical effects of posterior percutaneous full-endoscopic cervical foraminotomy in patients with osseous foraminal stenosis. ⋯ Posterior percutaneous full-endoscopic cervical foraminotomy can accomplish full nerve root decompression and is a safe, feasible procedure. Therefore, it can be a treatment option for patients with osseous foraminal stenosis.

Case Reports
Intraventricular Meningioma Resection with Post-Operative Ischemia of the Lateral Geniculate Nucleus.
Intraventricular meningiomas comprise 0.5%-3% of intracranial meningiomas. They often cause obstructive hydrocephalus and commonly are treated with surgical resection or stereotactic radiosurgery. ⋯ Care must be taken to avoid visual pathways along the lateral ventricle wall and the nearby arterial supply of the lateral geniculate nucleus from the choroidal arteries when resecting intraventricular tumors.
