Robot-Assisted Versus Fluoroscopy-Assisted Cortical Bone Trajectory Screw Instrumentation in Lumbar Spinal Surgery: A Matched-Cohort Comparison.
The aim of the present study was to compare the accuracy and safety of TiRobot system-assisted with those of fluoroscopy-assisted cortical bone trajectory screw placement in lumbar spinal surgery. ⋯ Robot-assisted screw placement is more accurate and safe compared with fluoroscopy-assisted placement for lumbar spinal cortical bone trajectory instrumentation.

Bloodless dry fields are indispensable for successful and safe neurosurgical operations using microscopes. Appropriate irrigation and suction systems are needed to obtain clear surgical fields. We invented a novel malleable continuous suction tube to address this need. ⋯ The newly developed malleable suction tube is effective for microsurgery.

Glioblastoma is the most common primary malignant tumor of the brain. Common radiologic findings using initial computed tomography (CT) reveal an intra-axial lesion with perifocal edema. Here, we present a rare case of diffuse subarachnoid hemorrhage (SAH) detected on an initial CT image in a patient without intracranial aneurysm in whom the final diagnosis was glioblastoma. ⋯ We present a rare case of glioblastoma mimicking SAH of unknown etiology and recommend including glioblastoma in the differential diagnosis of SAH of unknown etiology.

Patients with large and giant intracranial aneurysms (IAs) can experience neurological deterioration within 6 months after successful flow diverter (FD) placement. The purpose of the present study was to assess whether the occurrence of neurological deterioration can be linked to IA expansion within 6 months after FD treatment. ⋯ The volume of large and giant IAs can increase in the first 6 months after FD treatment. More patients presenting with mass effect-related symptoms showed IA expansion than patients with ischemia-related symptoms.

Proper treatment for chronic occluded internal carotid artery (ICA) has not been determined. Endovascular recanalization may cause arterial injury and distal embolism. Hybrid recanalization for chronic occluded ICA was performed, and its safety and effectiveness were estimated. ⋯ Hybrid recanalization by carotid endarterectomy and arterial angioplasty is a safe treatment method for chronic totally occluded ICA. Recanalization was more likely to be successful if the ICA was occluded by the plaque at the carotid bifurcation with the thrombus anterograde to the cavernous segment than if the artery was occluded by the plaque at the ophthalmic or supraclinoid segment with the thrombus retrograde to the cervical segment.
