Surgical education has increasingly relied on electronic learning. In particular, online operative videos have become a core resource within neurosurgery. We analyze the forums for neurosurgical operative videos.

Operative videos from 5 sources were reviewed 1) the NEUROSURGERY Journal YouTube channel; 2) the American Association of Neurological Surgeons Neurosurgery YouTube channel; 3) The Neurosurgical Atlas Operative Video Cases; 4) Operative Neurosurgery; and 5)Neurosurgical Focus Video. Title, year of publication, senior author, institution, country, and subspecialty were documented for each video.

A total of 1233 videos showing 1247 surgeries were identified. Ten videos included >1 surgery; of those, there was a median of 2 surgeries (interquartile range, 2.0-2.5) per video. The most frequently represented subspecialties included vascular (48.3%), tumor (35.2%), and skull base surgery (27.5%), with almost 40% of videos showing >1 category. Videos were submitted by investigators from 28 countries, but 82.1% of the videos originated in the United States.

Neurosurgical operative videos have become increasingly common through a variety of online platforms. JNJ-64264681 order Future efforts may benefit from collecting videos from underrepresented regions and subspecialties, providing long-term follow-up data and showing techniques for managing complications.

The occurrence of large-vessel occlusion in young patients with coronavirus disease 2019 (COVID-19) infection has been exceedingly rare. An extensive review of reported studies revealed a few reported cases. In the present report, we have described the clinical presentation, radiological findings, and outcome of large-vessel occlusion in a young patient with COVID-19 and reviewed the pertinent reported data on this condition.

A 31-year-old woman was in her usual state of health until she had presented with a 3-day history of right-sided weakness, slurred speech, and decreased vision. The patient had been taken to several hospitals where she had been treated conservatively with analgesics and discharged. Shortly thereafter, her weakness had become progressive. She had become severely dysarthric and unresponsive. On arrival to the emergency department, her physical examination revealed that she was stuporous, with a Glasgow coma scale of 10 (eye response, 3; verbal response, 2; motor response, 5). The National Institutes of Health Stroke Scale score was 19 on presentation. Brain computed tomography and computed tomography venography revealed an occluded left internal carotid artery and left middle cerebral artery with subacute left middle cerebral artery territory infarction and midline shift. Computed tomography angiography revealed complete occlusion of the left common carotid artery. An emergent decompressive craniectomy was successfully performed. The patient was shifted to the intensive care unit. She was later found to be positive for COVID-19.

Although rare, patients with COVID-19 can present with large-vessel occlusion. Prompt identification of COVID-19-related coagulopathy is essential to assess young patients with clinical manifestations of infarction.

Few studies provide insight into risk factors (RFs) associated with postoperative deep vein thrombosis (DVT) following elective spinal surgery. DVTs are detrimental in this population because of the risk of pulmonary embolization or surgical site hemorrhage with treatment.

Elective spine surgery patients have a low incidence of DVT, thus a case-control study was selected to investigate RFs associated with postoperative, symptomatic DVT.

Cases were matched to controls in a 12 ratio based on surgery type. Risk of having a prior DVT and choice of subcutaneous heparin dosing following surgery was analyzed in a multivariate regression model with other potentially confounding variables.

A total of 195 patients were included in this study. Independent of patient age, history of DVT was associated with postoperative symptomatic DVT (odds ratio [OR], 4.09; 95% confidence interval [CI], 1.22-13.78). Two versus 3 times daily postoperative heparin dosing (OR, 1.56; 95% CI, 0.32-7.56), surgery length (OR, 1.32; 95ients may help reduce the rate of symptomatic, postoperative DVT.
Hemorrhagic contusion in cervical spinal cord injury (CSCI) is poorly understood. We investigated hemorrhagic expansion in patients with CSCI with an assigned elevated mean arterial pressure (MAP) goal of >85 mm Hg. The change in hemorrhagic area and long-term follow-up data ≥6 months after injury was studied.

A retrospective review was performed from 2005 to 2016 to identify patients with motor complete CSCI with 2 cervical magnetic resonance imaging (MRI) scans within 7 days of injury showing evidence of hemorrhagic contusion and assigned a MAP goal of >85 mm Hg for 7 days. T2-weighted MRI was used to calculate the hemorrhagic surface area in the sagittal plane. A calculated MAP was recorded for each blood pressure measure between the initial and follow-up MRI scans. The American Spinal Injury Association impairment scale (AIS) and American Spinal Injury Association motor scores were recorded at the final follow-up examination at ≥6 months.

A total of 193 patients were identified. The mean changs for patients with CSCI and hemorrhagic contusion. Elevated MAPs did not significantly increase the risk of hemorrhagic expansion in those with CSCI. We have also reported the use of hemorrhagic contusion size as a potential radiographic biomarker for neurological outcomes.
We report the first case of cervical spine chondrosarcoma in a Wilms tumor survivor.

A 52-year-old female patient presented with myelopathic symptoms including poor balance, difficulty walking, and numbness of both feet. A magnetic resonance imaging of the spine showed a mass at the right C7-T1 foramen causing significant cord compression. The patient's symptoms improved after posterior decompression and fusion with excision of the tumor.

Through our experience with this case, we would like to suggest a possible unknown genetic syndrome predisposing patients with Wilms tumor to chondrosarcoma as secondary neoplasms. We would also like to re-emphasize the need for vigilance when assessing patients with a history of Wilms tumor.
