Emergent and Urgent Craniotomies in Pediatric Patients: Resource Utilization and Cost Analysis.

BACKGROUND: Pediatric neurosurgeons are occasionally tasked with performing surgery expeditiously to preserve a child's neurologic faculties and life. OBJECTIVE: This study examines the etiologies, outcomes, and costs for urgent or emergent craniotomies at a Level I Pediatric Trauma center over a 7-year time period. METHODS: A retrospective review was conducted for each patient who underwent an emergent or urgent craniotomy within 24 hours of presentation between January 2010 and April 2017. Demographic, clinical, and surgical details were recorded for a total of 48 variables. Any readmission within 90 days was analyzed. Hospital charges for each admission and readmission were collected and adjusted for inflation to October 2018 values. RESULTS: Among the 223 children who underwent urgent or emergent craniotomies, the majority were admitted for traumatic injuries (n = 163, 73.1%). The most common traumatic mechanism was fall (n = 51, 22.9%), and the most common non-traumatic cause was tumor (n = 21, 9.4%). Overall, craniotomies were typically performed for hematoma evacuation of one type or combination (n = 115, 51.6%) during off-peak times (n = 178, 79.8%). Seventy-seven (34.5%) subjects experienced 1 or more postoperative events, 22 of whom returned to the operating room. There were 13 (5.8%) and 33 (14.8%) readmissions within 30 days and 90 days of discharge, respectively. Non-trauma patients (compared with trauma patients) and polytrauma (compared with isolated head injury) had greater healthcare needs, resulting in higher charges. CONCLUSION: Most urgent or emergent pediatric craniotomies were performed for the treatment of traumatic injuries involving hematoma evacuation, but non-traumatic patients were more complex requiring greater resources.

Melanotic Neuroectodermal Tumor of Infancy with Involvement of the Superior Sagittal Sinus.

Melanotic neuroectodermal tumor of infancy (MNTI) is a rare lesion that typically manifests in the first year of life, most commonly involving the facial bones. We present 2 infants with MNTI involving the posterior skull with associated compression of the superior sagittal sinus (SSS). A review of the anatomical locations of MNTI is offered, and the implications of SSS involvement are described. This represents the first known description of MNTI with involvement of the posterior SSS.

Eight-second MRI scan for evaluation of shunted hydrocephalus.

INTRODUCTION: Pediatric patients harboring shunts placed early in life are subjected to numerous radiographic studies during development of their central nervous system. Radiation is detrimental to these young patients. MRI avoids the risk of radiation but is thought more difficult due to the increased time a young patient must lie motionless during scan acquisition. Optimal radiographic interrogation would be quick, radiation-free, and allow adequate ventricular evaluation. METHODS: We queried the electronic medical records system of the senior author (SE) for the terms "hydrocephalus" and "shunt malfunction." All patients currently younger than 18 years were included. In the last 5 years, pediatric patients have been evaluated in an office setting with a limited MRI sequence (T1 sagittal, T2 axial, T1 axial, and DWI) lasting a total of 178 s. In the event of significant motion artifact, the total sequence is abandoned and an 8-s T2 diffusion-weighted scan is performed. RESULTS: Forty-four patients were included in the study (20 males, average age 10.4 yrs). Eighty-eight rapid acquisition scans were obtained. Adequate ventricular evaluation was performed without sedation in every case. In each instance where there was motion, the 8-s scan provided adequate ventricular evaluation. CONCLUSION: Rapid acquisition MRI scanning avoids the deleterious cumulative effects of radiation in pediatric patients and allows adequate evaluation of the ventricles without the need for sedation.
