Reduction cranioplasty may be indicated to address functional or cosmetic sequelae of hydrocephalic macrocephaly. With the advent of CAD/CAM digital workflow, surgeons can design and fabricate craniotomy guides, templates, and models that allow for precise cranial reconstruction. Although there are several advantages of virtual planning, pre-determined surgical plans may limit intraoperative flexibility, requiring surgeons to troubleshoot errors in pre-operative planning or model design.

Objective: Common complications after spinal fusion, such as pseudoarthrosis, cage subsidence, or instrumentation failure, are affected by patients' bone quality. The cervical-vertebral bone quality (C-VBQ) score, a magnetic resonance imaging (MRI)-based adaption of the lumbar vertebral bone quality (VBQ) score, was developed by 3 separate research groups simultaneously to evaluate bone quality in cervical spinal fusion patients. We present the first analysis comparing these scoring methods to the well-validated VBQ score.

Background And Importance: Extracranial carotid artery pseudoaneurysm is a rare entity with potential etiologies including infection, blunt trauma, postsurgical atherosclerotic disease, and invasive neoplasia. Although the natural history of carotid pseudoaneurysm is difficult to determine because of its rarity, complications such as stroke, rupture, and local mass effect may occur at staggering rates.

Clinical Presentation: In this case, a middle-aged man presented with a tandem carotid, middle cerebral artery occlusion that was treated with a carotid stent and mechanical thrombectomy.

Background: Passive drainage post-surgical evacuation of symptomatic chronic subdural hematoma (cSDH) is currently standard of care. High rates of infection, drain occlusion, and recurrence are associated complications.

Objective: To explore the use of a novel double-lumen active automated irrigation and aspiration system, IRRAflow (IRRAS), for patients with cSDH and compared procedural and clinical outcomes against passive drainage alone with propensity score matching (PSM) and volumetric analysis.

Purpose: To determine risk factors increasing susceptibility to early complications (intraoperative and postoperative within 6 weeks) associated with surgery to correct thoracic and lumbar spinal deformity.

Methods: We systematically searched the PubMed and EMBASE databases for studies published between January 1990 and September 2021. Observational studies evaluating predictors of early complications of thoracic and lumbar spinal deformity surgery were included.

Background: Results of the management of superior cerebellar artery (SCA) aneurysms are typically reported in combination with those for all posterior circulation aneurysms. We report our experience with the management of SCA aneurysms and a systematic review of the endovascular management of these rare aneurysms.

Methods: Patients with saccular SCA aneurysms that were not associated with arteriovenous malformations and who presented to our institute between 2000 and 2017 were identified.

Background: Tethered cord syndrome occurs when there is abnormal tension on the distal spinal cord, which limits its elevation as patients grow. This results in stretching of the neural elements and microvasculature, resulting in both direct and ischemic injury.[7] Animal studies suggest that impairment of oxidative metabolic pathways may contribute to neuronal injury.

Background: Tension pneumocephalus is a rare complication after intracranial procedures and craniotomy. We report a rare case of intraventricular and subdural tension pneumocephalus occurring 2 months after repeat right-sided microvascular decompression (MVD) for recurrent trigeminal neuralgia.

Case Description: The patient in this case was a 79-year-old woman who presented with acute-onset confusion, headaches, nausea, and vomiting.
