Determining the appropriate surgical indications for obtunded octogenarians with traumatic acute subdural hematoma (aSDH) has been challenging. We sought to determine which easily available data would be useful adjuncts to assist in early and quick decision-making.We performed a single-center, retrospective review of patients aged ≥80 years with confirmed traumatic aSDH who had undergone emergent surgery. The clinical measurements included the Karnofsky performance scale score, Charlson comorbidity index, Glasgow coma scale (GCS), and abbreviated injury score. The radiographic measurements included the Rotterdam computed tomography score, aSDH thickness, midline shift, and optic nerve sheath diameter (ONSD). The neurologic outcomes were defined using the extended Glasgow outcome scale-extended (GOS-E) at hospital discharge and 3-month follow-up. The Pearson correlation coefficient was used to compare the ONSD with all clinical, radiographic, and outcome variables. Multivariate logistic regression was used to assess the relationship between the discharge and 3-month GOS-E scores between all clinical and radiographic variables.A total of 17 patients met the inclusion criteria. The mean age was 82.5 ± 1.6 years (range, 80-85 years), and the mean GCS score was 11.2 ± 4.1 (range, 4-15). The mean discharge and 3-month GOS-E scores were 3.4 ± 2.6 (range, 1-8) and 2.3 ± 2.1 (range, 1-7), respectively. We found significant negative correlations between the ONSD and the GCS score (r = -0.62; P0.01) and the ONSD and discharge GOS-E score (r = -0.49; P = 0.05). Multivariate analysis revealed a significant association between the abbreviated injury score and the discharge GOS-E score (P = 0.05).Octogenarians sustaining aSDH and requiring emergent surgery have poor outcomes. More data are needed to determine whether the ONSD can be a useful adjunct tool to predict the efficacy of emergent surgery.

Gamma knife radiosurgery (GKRS) is often performed to treat brain metastases (BrMs). Widely referenced guidelines have suggested post-treatment imaging studies at 3-month intervals. However, clinicians frequently obtain magnetic resonance imaging (MRI) studies at3 months after GKRS.We performed a retrospective medical record review study to assess the utility of early (3 months) MRI after GKRS in patients with BrMs.A total of 415 GKRS procedures were performed. For 325 patients, early MRI studies were obtained. A total of 31 patients had new or worsened neurological symptoms. The early MRI studies showed adverse findings in 25 patients (78%), which in 23 (72%) had resulted in a change in treatment. For 294 patients, no new or worsened neurological symptoms were found on early MRI studies. Of these 294 patients, 86 (29%) had ≥1 adverse finding on MRI, and 60 (20%) had a change in management as a result. However, no rapidly growing tumors or other emergent adverse findings were seen.Early MRI (within 3 months) after post GKRS will frequently show adverse findings even in asymptomatic patients, more often in patients aged65 years and patients with multiple treated BrMs. However, according to the nature of the adverse findings observed in our retrospective study, it is unlikely that the clinical outcomes would have been affected if the post-GKRS MRI studies had been deferred to 3 months after treatment. Our data support deferring post-GKRS MRI to 3 months after treatment in the absence of new neurological signs or symptoms.

BACKGROUND Primary decompressive craniectomy (DC) is commonly performed for patients with traumatic brain injury (TBI). Some, but not all patients, will benefit from invasive monitoring of intracranial pressure (ICP) after surgery. We intended to identify risk factors for elevated ICP after primary DC to treat TBI. METHODS A retrospective chart review study identified all patients at our institution who underwent primary DC for TBI during the study period and who had ICP monitors placed at the time of surgery. Various preoperative and intraoperative variables were assessed for correlation with the presence of postoperative elevated ICP. RESULTS Postoperative elevated ICP occurred in 36% of patients after DC. In univariate analysis, Glasgow Coma Scale

Objective We sought to determine whether a set of simple criteria can identify patients in the neuroscience intensive care unit (NICU) at high risk of poor outcome and delivery of nonbeneficial care early in the course of their illness. Secondarily, factors affecting limitation of care protocols were assessed. Methods We prospectively identified patients who were admitted to the NICU with partial loss of brainstem reflexes persisting for >24 hours due to an intrinsic lesion of the brain (trauma, stroke, hemorrhage, etc.). Results The study included 102 patients. Seventy-two of them died after a mean of 16 days (median: 8 days), and 23 remained comatose, locked-in, or in a vegetative state. Four were conscious and following commands, while 3 were minimally conscious, episodically obeying simple commands. Three out of 4 conscious patients were young males with traumatic brain injuries. Patients who remained full code spent a mean of 22.2 days in the NICU, compared with 10.4 for those who had withdrawal of care (P = 0.022) and 11.9 for patients who received a do-not-resuscitate order (P = 0.045). Time to death did not differ significantly between the groups. Overall, institution of various limitations of care protocols correlated positively with older age (odds ratio [OR] = 1.07, P = 0.0008), being treated on the neurology service (OR = 4.4, P = 0.043), and having health insurance (OR = 5.4, P = 0.03). Conclusions We identified simple criteria that can be used to identify patients in the NICU setting for whom continued aggressive care is likely nonbeneficial. Our analysis revealed demographic, social, and economic factors correlating with proxies' willingness to consider limitation of care.
