Objectives: To assess the prevalence of coagulopathy in postoperative neurosurgical patients and correlate it with the outcome.
Materials And Method: This longitudinal study was conducted in a tertiary care hospital in the Department of Pathology and Neurosurgery. Ethical approval was taken from the Institutional Ethical Committee - Human Research. Seventy-two (72) participants were recruited within 48 hours of surgery after obtaining consent. Complete clinical and surgical details were recorded. A 6.5 mL venous sample was collected and dispensed in two separate vials. The EDTA sample was run within 2 hours of collection on an automated hematology analyzer to obtain complete blood counts, including platelet count. The citrated sample was run on a fully automated coagulometer to determine PT, APTT, plasma fibrinogen, FVIII assay, and D-dimer levels. Subjects with a DIC-ISTH score of 5 or more were excluded. Coagulopathy was defined as three or more coagulation parameters deranged in a patient. All patients were followed up for the outcome. The outcome was correlated with coagulopathy, and a -value less than 0.05 was considered statistically significant.
Results: The study found that the number of hemostatic parameters deranged correlated with outcome (P < 0.001). The proportion of patients with coagulopathy was 32/72 (44.4%), while those without coagulopathy were 40/72 (55.6%). Of patients with coagulopathy, 87.5% (28/32) had an adverse outcome, while 12.5% (4/32) had a favorable outcome. The difference was found to be statistically significant (P < 0.001).
Conclusions: Coagulopathy, defined as the derangement of three or more parameters, is a predictor of poor outcomes in postoperative neurosurgical patients. This timely recognition of coagulopathy can help triage patients requiring appropriate blood products, significantly reducing morbidity and mortality associated with postoperative neurosurgical patients.

Neighborhood-level measures of socioeconomic status impact healthcare utilization and surgical outcomes in cervical spondylotic myelopathy patients in the Deep South.
J Neurosurg Spine

2Department of Neurosurgery, University of Alabama at Birmingham, Alabama.
Objective: The aim of this study was to evaluate the association of neighborhood-level and individual-level measures of socioeconomic status with readmission, complication rates, and postoperative length of stay of patients with cervical spondylotic myelopathy (CSM) in the Deep South.
Methods: The authors identified all patients undergoing surgical intervention for the treatment of CSM from November 2010 to February 2022 using Current Procedural Terminology and ICD-9/ICD-10 codes. Patient demographic, socioeconomic, perioperative, and postoperative data for each patient were collected via review of the electronic medical record.
Comparative outcomes of microsurgical dorsal root entry zone lesioning (DREZotomy) for intractable neuropathic pain in spinal cord and cauda equina injuries.

Treatment of neuropathic pain in patients with spinal cord injury (SCI) and cauda equina injury (CEI) remains challenging. Dorsal root entry zone lesioning (DREZL) or DREZotomy is a viable surgical option for refractory cases. This study aimed to compare DREZL surgical outcomes between patients with SCI and those with CEI and to identify predictors of postoperative pain relief.

Resection is often the primary treatment for large brain tumors but is less practical for multiple brain metastases (BM). Current guidelines recommend stereotactic radiosurgery (SRS) for untreated BMs or following the surgical removal of a solitary BM to reduce the risk of local tumor recurrence. Preoperative SRS (pre-SRS) shows promise with fewer complications and more precise targeting, but it lacks tissue diagnosis and may hinder wound healing.

Acute kidney injury (AKI) incidence after neurosurgical operations has been reported as 10-14%. The literature regarding the incidence of nosocomial acute kidney disease (AKD) following neurosurgery is scarce. This retrospective, single-center, observational study aimed to assess the impact of different anaesthetics on development of postoperative AKI and persistent AKD in neurosurgical patients.

Rathke's cleft cysts (RCCs) are benign, cystic lesions that account for less than 5% of cases in the pediatric population. While asymptomatic RCCs often require only conservative management, symptomatic cases may necessitate surgical intervention. Advances in surgical techniques have improved the safety of these procedures.
