The KCL026 human embryonic stem cell line was derived from an embryo donated for research that carried a mutation in the SMN1 gene encoding survival of motor neuron 1, telomeric (exons 7 and 8 deletion). Mutations in this gene are associated with spinal muscular atrophy. The ICM was isolated using laser microsurgery and plated on γ-irradiated human foreskin fibroblasts. Both the derivation and cell line propagation were performed in an animal product-free environment. Pluripotent state and differentiation potential were confirmed by in vitro assays...

Spinal vascular malformations (SVMs) are a heterogeneous group that can cause acute, subacute, or chronic spinal cord dysfunction. The majority of the patients present to neurosurgical attention after a protracted course with severe neurological dysfunction. Spinal vascular lesions comprise approximately 3-4 % of all intradural spinal lesions. They are pathologically similar to their intracranial counterparts, but their clinical impact is often comparatively worse. Early, correct recognition of the pathology is mandatory to halt the progression of the disease and minimize permanent spinal cord injury...

BACKGROUND/OBJECTIVE: Spinal dural arteriovenous fistulas (SDAVFs) require pretreatment angiography; embolization can be performed in the same session. To validate this approach, obliteration and morbidity rates of 'endovascular-first' (embolization and microsurgery in the case of embolization failures) must be compared with rates for 'microsurgery-first' (microsurgical ligation without attempted embolization) approaches. METHODS: We reviewed our institutional database (January 1998-October 2015) for SDAVFs, performing an intention-to-treat analysis comparing endovascular-first and microsurgery-first approaches...

Parkes Weber syndrome (PWS) is a congenital overgrowth disorder characterized by unilateral limb and axial hypertrophy, capillary malformations of the skin, and high-flow arteriovenous fistulas (AVFs). Spinal AVFs in the setting of PWS are challenging vascular lesions that often contain multiple arteriovenous (AV) shunts. The present case report highlights an adolescent girl with PWS who presented with a ruptured complex high-flow conus medullaris AVF. She was successfully treated with endovascular embolization and microsurgery...

The operative microscope has been a staple instrument in the neurosurgical operating room over the last 50 years. With advances in optoelectronics, options such as robotically controlled high magnification have become available. Such robotically controlled optoelectronic systems may offer new opportunities in surgical technique and teaching. However, traditionally trained surgeons may find it hard to accept newer technologies due to an inherent bias emerging from their previous background. We, therefore, studied how a medically naïve population in a pilot study would meet set microsurgical goals in a cadaver experiment using either a conventional operative microscope or BrightMatter™ Servo system, ​a robotically controlled optoelectronic system (Synaptive Medical, Toronto, Ontario, Canada)...

OBJECTIVE: The microvascular anatomy of spinal perimedullary arteriovenous fistulas (AVFs) is more complicated than that of dural AVFs, and occlusion rates of AVF after open microsurgery or endovascular embolization are lower in patients with perimedullary AVFs (29%-70%) than they are in those with dural AVF (97%-98%). Reports of intraoperative blood flow assessment using indocyanine green (ICG) video angiography in spinal arteriovenous lesions have mostly been for spinal dural AVFs. No detailed reports on spinal perimedullary AVFs are available...

UNLABELLED: In the 1970's many neurosurgeons gradually adapted microsurgical techniques to spine surgery as the benefits of magnification, illumination, and use of fine instruments in cranial surgery became apparent. In the early 1970 s, Robert W. Williams, а neurosurgeon in private practice in Las Vegas, Nevada, independently began to devise spinal microneurosurgical techniques with the goal of improving surgical outcome in lumbar and cervical surgery. Much of his initial work with microlumbar discectomies and microcervical foraminotomies was presented at annual meetings of the American Association of Neurological Surgeons and Congress of Neurological Surgeons in the 1970s and 1980s...

The synovial and ganglion cysts originating from the facet joint have been named under the name of the Juxtafacet cyst by the several researchers. They put forward that the synovial cyst originated from the synovial joint. But, they failed to clarify the pathophysiology of the formation of the ganglion cyst. In this case report, we reported a 67-year-old male patient was referred to the emergency from another center with the complaint of a left leg pain and weakness in the left foot and patient was treated with microchirurgical technique...

Spinal hemangioblastomas (HB) are relatively rare neoplasms with a high degree of vascularity. Therapy for symptomatic tumors involves total resection when possible. Due to the enriched blood supply of these neoplasms, there is a high risk of significant intraoperative blood loss, which can lead to perioperative complications. Preoperative embolization of HB has been suggested to reduce blood loss and operative morbidity, but its use remains controversial. Data on the risks and benefits of preoperative embolization for this tumor remains limited...

Traumatic injuries to PNS and CNS axons are not uncommon. Restoration of lost behaviors following severance of mammalian peripheral nerve axons (PNAs) relies on regeneration by slow outgrowths and is typically poor or nonexistent when after ablation or injuries close to the soma. Behavioral recovery after severing spinal tract axons (STAs) is poor because STAs do not naturally regenerate. Current techniques to enhance PNA and/or STA regeneration have had limited success and do not prevent the onset of Wallerian degeneration of severed distal segments...
