Item An ischemic myelopathy case series: Flaccid paraplegia following a spike ball save and numbness while walking normally(Wolters Kluwer, 2023-06-30) Heckman, Caroline A.; Miller, Derryl J.; Kremer, Kelly M.; Martinez, Mesha L.; Jea, Andrew H.; Neurology, School of MedicineSpinal cord infarctions in children are rare and early magnetic resonance imaging studies are often negative. A high clinical suspicion must be maintained to identify stroke and initiate workup for underlying etiology to suggest appropriate treatment. We present two cases of spinal cord infarction without major preceding trauma. The first was caused by disc herniation and external impingement of a radiculomedullary artery and the second was due to fibrocartilaginous embolism with classic imaging findings of ventral and dorsal cord infarctions, respectively. These cases were treated conservatively with diagnostic workup and aspirin, though additional treatments which can be considered with prompt diagnosis are also explored in our discussion. Both cases recovered the ability to ambulate independently within months. Case 1 is attending college and ambulates campus with a single-point cane. Case 2 ambulates independently, though has some difficulty with proprioception of the feet so uses wheelchairs for long-distance ambulation.Item Occipital-Cervical Fusion and Ventral Decompression in the Surgical Management of Chiari-1 Malformation and Syringomyelia: Analysis of Data From the Park-Reeves Syringomyelia Research Consortium(Wolters Kluwer, 2021-01-13) CreveCoeur, Travis S.; Yahanda, Alexander T.; Maher, Cormac O.; Johnson, Gabrielle W.; Ackerman, Laurie L.; Adelson, P. David; Ahmed, Raheel; Albert, Gregory W.; Aldana, Phillipp R.; Alden, Tord D.; Anderson, Richard C.E.; Baird, Lissa; Bauer, David F.; Bierbrauer, Karin S.; Brockmeyer, Douglas L.; Chern, Joshua J.; Couture, Daniel E.; Daniels, David J.; Dauser, Robert C.; Durham, Susan R.; Ellenbogen, Richard G.; Eskandari, Ramin; Fuchs, Herbert E.; George, Timothy M.; Grant, Gerald A.; Graupman, Patrick C.; Greene, Stephanie; Greenfield, Jeffrey P.; Gross, Naina L.; Guillaume, Daniel J.; Haller, Gabe; Hankinson, Todd C.; Heuer, Gregory G.; Iantosca, Mark; Iskandar, Bermans J.; Jackson, Eric M.; Jea, Andrew H.; Johnston, James M.; Keating, Robert F.; Kelly, Michael P.; Khan, Nickalus; Krieger, Mark D.; Leonard, Jeffrey R.; Mangano, Francesco T.; Mapstone, Timothy B.; McComb, J.

Objective: To examine factors influencing the use of OCF and OCF/VD in a multicenter cohort of pediatric CM-1 and SM subjects treated with PFD. Methods: The Park-Reeves Syringomyelia Research Consortium registry was used to examine 637 subjects with cerebellar tonsillar ectopia ≥ 5 mm, syrinx diameter ≥ 3 mm, and at least 1 yr of follow-up after their index PFD. Comparisons were made between subjects who received PFD alone and those with PFD + OCF or PFD + OCF/VD. Results: All 637 patients underwent PFD, 505 (79.2%) with and 132 (20.8%) without duraplasty. A total of 12 subjects went on to have OCF at some point in their management (PFD + OCF), whereas 4 had OCF and VD (PFD + OCF/VD). Of those with complete data, a history of platybasia (3/10, P = .011), Klippel-Feil (2/10, P = .015), and basilar invagination (3/12, P < .001) were increased within the OCF group, whereas only basilar invagination (1/4, P < .001) was increased in the OCF/VD group. Clivo-axial angle (CXA) was significantly lower for both OCF (128.8 ± 15.3°, P = .008) and OCF/VD (115.0 ± 11.6°, P = .025) groups when compared to PFD-only group (145.3 ± 12.7°). pB-C2 did not differ among groups. Conclusion: Although PFD alone is adequate for treating the vast majority of CM-1/SM patients, OCF or OCF/VD may be occasionally utilized. Cranial base and spine pathologies and CXA may provide insight into the need for OCF and/or OCF/VD.
