Pediatric isolated penetrating traumatic vertebral artery injuries require urgent multidisciplinary management as they may lead to potentially fatal posterior circulation ischemia. ⋯ Endovascular treatment can be considered first line treatment of oral penetrating injuries to the vertebral artery, where the penetrating object has an anterior to posterior trajectory.

An 11-year-old girl had undergone posterior spinal fusion surgery for scoliosis. The surgery was complicated by intraoperative bleeding, and hemostasis was achieved by topically applying gelatin sponges. ⋯ Autopsy shortly after revealed that her death was associated with unintended intravascular entry of gelatin sponge fragments, resulting in an embolic event and secondary cardiopulmonary collapse.

Epidermoid Cyst of the Lumbar Spine after Lumbar Puncture: A Clinical, Radiographic, and Pathological Correlation.
Epidermoid cysts can rarely arise as a late complication of lumbar puncture. We describe a young man who had a remote history of a lumbar puncture and who was subsequently found to have a lumbar spinal epidermoid cyst on imaging, after presenting with lower extremity radicular pain. ⋯ Lumbar spinal epidermoid cysts may be either congenital or secondary to an iatrogenic cause. This patient had a remote history of lumbar puncture during workup for meningitis as a child. As a complication of a lumbar puncture, the formation of an epidermoid cyst can occur and is thought to be the result of implanted cutaneous tissue. This case provides a comprehensive illustration of the clinical, radiographic, intraoperative, and pathologic findings consistent with an iatrogenic epidermoid cyst.

Minimally invasive neurosurgical approaches reduce patient morbidity by providing the surgeon with better visualization and access to complex lesions, with minimal disruption to normal anatomy. The use of rigid or flexible neuroendoscopes, supplemented with a conventional stereoscopic operating microscope, has been integral to the adoption of these techniques. Neurosurgeons commonly use neuroendoscopes to perform the ventricular and endonasal approaches. It is challenging to learn neuroendoscopy skills from the existing apprenticeship model of surgical education. The training methods, which use simulation-based systems, have achieved wide acceptance. Physical simulators provide anatomic orientation and hands-on experience with repeatability. Our aim is to review the existing physical simulators on the basis of the skills training of neuroendoscopic procedures. ⋯ The state of simulation systems demands collaborative initiatives among translational research institutes. They need improved fidelity and validation studies for inclusion in the surgical educational curriculum. Learning should be imparted in stages with standardization of performance metrics for skills evaluation.

Surgical scalpel broken is rarely reported in posterior lumbar discectomy or fusion surgeries, but when it happens and even the broken part is deeply located in the disk space, there is no guideline to remove it during the initial surgery. ⋯ Arthroscopic retrieval of a broken scalpel deeply located in the intradiskal space is recommended as an alternative method when conventional effort is unable to remove it, especially when the broken blade migrates anteriorly, which may provoke catastrophic consequences.
