Spinal subdural hematomas (SSDHs) are rare and usually associated with bleeding diatheses, trauma, iatrogenic injury, spinal vascular malformations, or intraspinal tumors. ⋯ In most cases, SSDHs after intracranial surgery resolve with conservative treatment; however, as shown in our case, surgery may be required if there is progressive neurologic decline. Neurosurgeons should be aware of this potential complication after intracranial surgery; a magnetic resonance imaging of the spine may be indicated if there is unexplained lower extremity pain or weakness.

Flexible ultrathin endoscope integrated with irrigation suction apparatus for assisting microneurosurgery.
Endoscopy can observe the anatomical components in a deeply located and/or hidden area during neurosurgical procedures under the operating microscope. We have newly developed a flexible ultrathin endoscope integrated with irrigation suction apparatus (FUEISA) to visualize deeply located and/or hidden areas for assisting microneurosurgery. ⋯ The FUEISA system can be applied with safe manipulation, which was remarkably useful for confirmation of the presence of perforators and cranial nerves behind the lesions, particularly anatomical components located in deep and/or hidden areas during clipping of cerebral aneurysms.

Patient-reported outcome measures (PROMs) are the most widely accepted means of measuring outcomes after spine procedures. We sought to determine the current status of worldwide use of PROMs in Latin America (LA), Europe (EU), Asia Pacific (AP), North America (NA), and Middle East (ME) to determine the barrier to its full implementation. ⋯ We found that 31.9% of spine surgeons do not use the PROMs questionnaire routinely. This appears to occur because of lack of knowledge regarding their importance, absence of reimbursement for this extra work, minimal financial support for clinical research, the cost of implementation, and lack of concern among physicians.

Parkinson disease (PD) is a major risk factor during spine surgery, and its frequency is increasing as the population ages. The study aim was to examine the influence of PD specifically on lumbar decompression surgery. ⋯ There is a significantly greater rate of perioperative complications in patients with PD undergoing elective decompression surgery. Although the difference in major complication rates was minimal, minor complications were more frequent in patients with PD.

Although indirect bypass surgery is an effective treatment option for patients with ischemic-onset moyamoya disease (MMD), the time point after surgery at which the patient's hemodynamic status starts to improve and the time point at which the improvement reaches a maximum have not been known. The objective of the present study is to evaluate the hemodynamic status time course after indirect bypass surgery for MMD, using dynamic susceptibility contrast-magnetic resonance imaging (DSC-MRI). ⋯ The amelioration of cerebral hemodynamics by indirect bypass surgery began soon after surgery and gradually reached a maximum at 3 months after surgery. DSC-MRI detected small changes in hemodynamic improvement, which are suspected to be caused by the initiation of angiogenesis and arteriogenesis in the early postoperative period.
