Intraoperative pathologic diagnosis traditionally involves frozen section histopathology, which may be labor and time intensive. Indeed, a technique that streamlines the acquisition and evaluation of intraoperative histologic data may expedite surgical decision-making and shorten operative time. Stimulated Raman histology (SRH) is an emerging technology that allows for more rapid acquisition and interpretation of intraoperative histopathologic data.
A blinded, prospective cohort study was performed for 82 patients undergoing resection for a central nervous system tumor. Of these, 21 patients were diagnosed with glioma either intraoperatively or postoperatively on permanent section histology and included in this study. Time to diagnosis (TTD) and diagnostic accuracy relative to permanent section (the gold standard) were compared between SRH-based diagnosis and conventional frozen section histology. Diagnostic concordance with permanent section was also compared between frozen histopathology and SRH diagnosis.
Diagnostic accuracy was not significantly different between methods (P= 1.00). Diagnostic concordance was not significantly different between methods when comparing 95% confidence intervals for kappa values (κ= 0.215; κ= 0.297; κ= 0.369). SANT-1 Lastly, mean TTD was significantly shorter with SRH-based diagnosis compared with frozen section (43 vs. 9.7 minutes, P < 0.0001). SRH was able to identify key features associated with varying glioma types.
SRH allows for rapid intraoperative diagnosis without sacrificing diagnostic accuracy. SRH may serve as a promising adjuvant to conventional histopathology to expedite intraoperative pathology consultation and surgical decision-making.

There is a paucity of information regarding the optimal timing of restarting antiplatelet therapy (APT) and anticoagulation therapy (ACT) after traumatic subdural hematoma (tSDH). Therefore, we sought to report our experience at a single level 1 trauma center with regard to restarting APT and/or ACT after tSDH.
A total of 456 consecutive records were reviewed for unplanned hematoma evacuation within 90 days of discharge and thrombotic/thromboembolic events before restarting APT and/or ACT.
There was no difference in unplanned hematoma evacuation rate in patients not receiving APT or ACT (control) compared with those necessitating APT and/or ACT (6.4% control, 6.9% APT alone, 5.8% ACT alone, 5.4% APT and ACT). There was an increase in post-tSDH thrombosis/thromboembolism in patients needing to restart ACT (1.9% APT alone, P= 0.53 vs. control; 5.8% ACT alone, P= 0.04 vs. control; 16% APT and ACT; P < 0.001 vs. control). Subgroup analysis revealed that patients with coronary artery disease necessitatingood thinners should be given on a case-by-case basis.
This study compares the postsurgical course of frontotemporal craniotomies conducted "awake" under regional anesthesia (RA) versus "asleep" under general anesthesia (GA) to investigate postoperative recovery, pain, opioid use, and anesthesia-related side effects.
We retrospectively reviewed craniotomies for supratentorial, intra-axial tumors with frontotemporal exposure. Chronic opioid use and emergent cases were excluded. Primary outcomes included pain scores on a 0-10 numerical rating scale, opioid use as oral morphine milligram equivalence, first time to opioid use, nausea, and sedation on the Richmond Agitation and Sedation Scale (RASS). Secondary outcomes included postoperative seizures, Karnofsky Performance Scale (KPS) status, and hospital length of stay (LOS).
A total of 91 patients met inclusion criteria 56 underwent a craniotomy under RA versus 35 under GA. Demographics and operative characteristics were similar between cohorts. A significant reduction in both postoperative pain and opioid use was observed among RA versus GA (first postoperative pain score 2 vs. 5, P < 0.01; postoperative day [POD] 0 median pain score 2.5 vs. 4, P < 0.01; POD 0 mean opioid in mg 14.49 vs. 24.43, P < 0.01). The time until patients requested opioids for pain after surgery was prolonged for RA versus GA [mean 7.23 vs. 3.42 hours, P < 0.01). Somnolence (RASS < 0) on POD 0 was significantly reduced among RA versus GA, with 23% versus 43%. Both cohorts had equivocal postsurgical outcomes such as seizures, KPS, and hospital LOS.
Frontotemporal craniotomy under RA during awake craniotomies provides better pain control, a reduction in opioid use, and less somnolence in the early postoperative period.

To report our experience using the scan-and-plan workflow and review current literature on surgical efficiency, safety, and accuracy of next-generation robot-assisted (RA) spine surgery.
The records of patients who underwent RA pedicle screw fixation were reviewed. The accuracy of pedicle screw placement was determined based on the Ravi classification system. To evaluate workflow efficiency, 3 demographically matched cohorts were created to analyze differences in time per screw placement (defined as operating room [OR] time divided by number of screws placed). Group A had <4 screws placed, Group B had 4 screws placed, and Group C had >4 screws placed. Intraoperative errors and postoperative complications were collected to elucidate safety.
Eighty-four RA cases (306 pedicle screws) were included for analysis. The mean number of screws placed was 2.1 ± 0.3 in Group A and 6.4 ± 1.2 in Group C; 4 screws were placed in Group B patients. The accuracy rate (Ravi grade I) was 98.4%. Screw placement time was significantly longer in Group A (101 ± 37.
