Although external landmarks and trajectories for external ventricular drainage have been described for the freehand-guided method, no standard trajectory has been reported for deep-seated intracerebral hemorrhage (ICH). This article presents a freehand-guided catheter insertion technique for deep-seated spontaneous ICH using external landmarks. ⋯ For patients with basal ganglia hemorrhage, freehand-guided catheter insertion and hematoma aspiration with subsequent fibrinolysis is a feasible procedure that shortens procedural times. The described technique could be used as an alternative method because it can be performed when the patient is in a critical state without additional equipment.

To evaluate the usefulness of 3-dimensional (3D) printed models as an aid for the treatment of complex CVJ anomalies. ⋯ The patient-specific 3D printed model would be an effective tool for evaluation of the reducibility of the atlantoaxial dislocation and basilar invagination, decision making in choosing the optimal surgical approach and way of fixation, and precise placement of the screw while protecting the vertebral artery and spinal cord. The risk of neurovascular injury was minimized, and encouraging outcomes were achieved with the aid of this technique.

Cystic sellar masses (CSMs) pose diagnostic and therapeutic challenges associated with subtotal cyst wall resection, cerebrospinal fluid (CSF) leak repair, and disease recurrence. Current magnetic resonance imaging (MRI) interpretation often cannot reliably differentiate CSMs, mandating adaptable intraoperative strategies. We reviewed our diagnostic and therapeutic experience after endoscopic endonasal approaches (EEAs) for CSMs. ⋯ Surgeons must prepare for versatile management strategies of CSMs based on pretest probability associated with MRI and intraoperative findings. Outcomes after EEA for CSMs show low complication profiles and excellent rates of headache and visual improvement, albeit lower rates of endocrine normalization.

To identify and reveal the sensitivity and efficiency of dynamic somatosensory evoked potentials (DSSEPs) in the diagnosis of cervical spondylotic myelopathy (CSM). ⋯ The percentage change in amplitude was obvious during cervical dynamic motion, with records from LMC2 and LUC2 being predictive of CSM diagnosis; dynamic SSEPs provided a simple, accurate, and noninvasive supplementary test for the diagnosis of complicated CSM.

To evaluate the feasibility to treat complex internal carotid aneurysms by superficial temporal artery trunk-radial artery-middle cerebral artery (STAT-RA-MCA) bypass combined with balloon occlusion of internal carotid artery. ⋯ STAT-RA-MCA bypass combined with balloon occlusion of internal carotid artery is feasible for the treatment of complex internal carotid aneurysms.
