Traumatic spinal cord injury (SCI) remains a devastating condition with no proven effective treatment options available. In a prior single-arm study of patients with thoracic complete SCI (INSPIRE; ClinicalTrials.gov, NCT02138110), acute implantation of an investigational bioresorbable polymer scaffold (Neuro-Spinal Scaffold [NSS]) appeared to be safe through 24 months postimplantation and was associated with an American Spinal Injury Association Impairment Scale (AIS) conversion rate that exceeded historical controls. Here, we evaluated whether NSS implantation demonstrates probable benefit for safety and neurological recovery in patients with thoracic complete SCI vs standard-of-care spine surgery. ⋯ In this small group of patients with thoracic complete (AIS A) SCI, implantation of an intraparenchymal bioresorbable scaffold did not produce probable clinical benefit. However, this study provides evidence that surgical intervention in an injured spinal cord parenchyma may be performed safely.

Flow Redirection Endoluminal Device (FRED) X is a new generation flow diverter with an antithrombotic surface coating. This study compares the procedural safety and short-term efficacy of FRED X with its uncoated predecessor, the FRED. ⋯ This study indicates an improved ischemic risk profile of FRED X while maintaining a favorable efficacy profile, warranting further study and translation into clinical use.

This study explores perceived cognitive function in preoperative cranial neurosurgical patients and its association with neuropsychological testing (NPT). ⋯ Perceived cognitive function in neurosurgical patients appears to be strongly predicted by demographic factors, with mental health variables being robust predictors. Perceived cognition is not a proxy for measured cognitive function.

Traumatic acute subdural hematoma (ASDH) is a medical emergency that requires prompt neurosurgical intervention. Urgent surgical evacuation may be performed with craniotomy (CO) and decompressive craniectomy (DC). However, a meta-analysis evaluating confounders, pooled functional outcomes, and mortality analyses at different time points has not been performed. ⋯ Patients with ASDH undergoing DC across unmatched cohorts had a worse GCS at admission. Although ASDH mortality was lower in the CO group, these findings are derived from unmatched cohorts, potentially confounding previous analyses. Notably, population-matched studies, such as the RESCUE-ASDH trial and PSM cohorts, showed similar effectiveness in mortality and functional outcomes between CO and DC. Reoperation and complication rates were comparable among surgical approaches. Considering the prevalence of unmatched cohorts, our findings highlight the need of future clinical trials to validate the findings of the RESCUE-ASDH trial.
