In Brief
The objective of the study was to identify clinical and radiological variables that predict the need for critical care intervention in patients after mechanical thrombectomy. A combination of clinical and radiological factors were identified that can be used to identify a group of postthrombectomy patients who may not require intensive care admission. The authors designed an intensive care unit clearance protocol that can be used to optimize resource utilization and improve care for postthrombectomy patients.

Matching the surgical with the conceptual center of rotation (COR) is difficult with pedicle subtraction osteotomy (PSO) and vertebral column resection (VCR). The authors aimed to examine sagittal correction geometry and surgical COR in three-column osteotomy. In PSO and VCR, the COR was mainly in the anterior and anterior or middle column, respectively. Surgical and conceptual COR matched in 65% and 31% of cases, respectively. Matching is difficult and failed in about two-thirds of patients. To avoid sagittal translation, the use of temporary rods, tracking rods, or special instruments for correction is recommended.

Researchers applied MRI to explore conus medullaris (CM) migration in early infancy. The CM of term infants reached the normal adult level at birth–i.e., on average between the L1–2 intervertebral disc and the inferior border of the L2 vertebra–and did not ascend during childhood. The postnatal migration process of CM remains unclear, and MRI has yet to be used to investigate the normal CM level in early infancy.

Anterior cerebral artery A1 segments proximal to anterior communicating artery (ACoA) aneurysms were analyzed and shown to demonstrate firehose-like progressive tapering, resulting in aneurysmogenic hemodynamic conditions at the bifurcation apex. This upstream tapering phenomenon previously documented in end-vessel middle cerebral artery bifurcation aneurysms was confirmed in communicating ACoA lesions, together forming > 50% of intracranial aneurysms. Vessel tapering associated with aneurysm presence emerges as a generalizable and universal finding, warranting future analysis into its clinical relevance and therapeutic potential.

The authors investigated functional, oncological, and quality-of-life (QOL) outcomes in a large series of patients who underwent surgery for cauda equina ependymoma (CEE) and myxopapillary ependymoma (MPE). Important findings were that larger tumors were associated with recurrences and worse outcomes, surgery should be aimed at achieving en bloc gross-total resection, and some features of MPE are associated with higher recurrence rates. Outcomes are usually favorable, but the mean QOL after treatment is inferior to that of the general population. This study may contribute to optimization of treatment and preoperative counseling of CEE patients.
