Use of the Subdural Hematoma in the Elderly (SHE) Score to Predict 30-Day Mortality After Chronic Subdural Hematoma Evacuation.

BACKGROUND: The Subdural Hematoma in the Elderly (SHE) score has been recently developed to assess the 30-day mortality in acute and chronic subdural hematomas in patients >65 years and has shown good reliability. We aimed to validate the SHE score's accuracy to predict 30-day mortality on a homogeneous cohort of patients undergoing surgical chronic subdural hematoma evacuation at our Institution. We also investigated whether the SHE score could reliably predict the occurrence of 30-day chronic subdural hematoma recurrence needing surgery. METHODS: We included patients from our prospectively collected database from January 2018 to January 2021. Patients with the availability of the following information were enrolled: age, Glasgow Coma Scale score on admission, hematoma volume, medical history, and outcome at 30 days. The SHE score was calculated for each patient, and the association between greater scores and 30-day mortality was investigated and its ability to predict 30-day and disease recurrence. Statistical significance was assessed for P < 0.05. RESULTS: Three hundred twenty-one patients were included. Of them, 40 (12.5%) displayed mortality within 30-day: specifically, 0% of the group of patients with SHE score = 0, 4.3% of SHE score = 1, 14.5% of SHE score = 2, 39.3% of SHE score = 3, and 37.5% of SHE score = 4, with a statistically significant linear trend between greater SHE scores and 30-day mortality rates (P < 0.001, area under the curve 0.75 [0.67-0.82]). No significant association of the SHE score with the risk of recurrence needing surgery was detected (P = 0.4). CONCLUSIONS: The SHE score proved helpful in predicting 30-day mortality in patients with chronic subdural hematomas, but no utility was observed to predict disease recurrence.

Predictive Value of Swab Cultures for Cryopreserved Flaps During Delayed Cranioplasties.

OBJECTIVE: To assess the predictive value of swab cultures of cryopreserved skull flaps during cranioplasties for surgical site infections (SSIs). METHODS: A retrospective review was conducted of consecutive patients who underwent delayed cranioplasties with cryopreserved autografts between 2009 and 2017. The results of cultures obtained from swabs and infected surgical sites were assessed. The accuracy, sensitivity, and specificity of swab cultures for SSIs were evaluated. RESULTS: The study included 422 patients categorized into two groups, swab and nonswab, depending on whether swab cultures were implemented during cranioplasties. The overall infection rate was 7.58%. No difference was seen in infection rates between groups. There were 18 false-positive and no true-positive swab culture results. All bacteria between swab cultures and SSI cultures were discordant. Meanwhile, there were 19 false-negative swab cultures. The results showed high specificity but low sensitivity for swab cultures to predict SSI occurrence and the pathogens. CONCLUSIONS: Owing to low accuracy and sensitivity, swab cultures of cryopreserved autografts should not be routinely performed during delayed cranioplasties.

Investigation of Asleep versus Awake Motor Mapping in Resective Brain Surgery.

OBJECTIVE: To develop an asleep motor mapping paradigm for accurate detection of the corticospinal tract during glioma surgery and compare outcomes with awake patients undergoing glioma resection. METHODS: A consecutive cohort of adult patients undergoing craniotomy for suspected diffuse glioma with tumor in a perirolandic location who had awake or asleep cortical and subcortical motor mapping with positive areas of motor stimulation were assessed for postoperative extent of resection (EOR), permanent neurological deficit, and proximity of stimulation to diffusion tensor imaging-based corticospinal tract depiction on preoperative magnetic resonance imaging. Outcome data were compared between asleep and awake groups. RESULTS: In the asleep group, all 16 patients had improved or no change in motor function at last follow-up (minimum 3 months of follow-up). In the awake group, all 23 patients had improved function or no change at last follow-up. EOR was greater in the asleep group (mean [SD] EOR 88.71% [17.56%]) versus the awake group (mean [SD] EOR 80.62% [24.44%]), although this difference was not statistically significant (P = 0.3802). Linear regression comparing distance from stimulation to corticospinal tract in asleep (n = 14) and awake (n = 4) patients was r = -0.3759, R2 = 0.1413, P = 0.1853, and 95% confidence interval = -0.4453 to 0.09611 and r = 0.7326, R2 = 0.5367, P = 0.2674, and 95% confidence interval = -7.042 to 14.75, respectively. CONCLUSION: In this small patient series, asleep motor mapping using commonly available motor evoked potential hardware appears to be safe and efficacious in regard to EOR and functional outcomes.

Placement of Wound Drain After Anterior Circulation Aneurysm Clipping: A Single-Center Retrospective Study.

OBJECTIVE: Wound drain used to be a routine procedure after craniotomy for aneurysm clipping, although this was not based on clinical evidence. The purpose of our study was to determine the necessity of wound drain placement after anterior circulation aneurysm surgery. METHODS: Retrospective analysis of patients with anterior circulation aneurysms treated by clipping in the Department of Neurosurgery, Wuhan University Zhongnan hospital from January 2019 to December 2019 was carried out. Demographic and clinical data, including age, sex, body mass index, disease history, results of the laboratory and imaging examinations, and surgical logs, were reviewed. RESULTS: A total of 236 patients (90 male and 146 female) were included in the analysis and were divided into a Drain group and a No Drain group according to whether postoperative wound drainage was applied. There was no statistical difference in the incidence of a postoperative extradural hematoma between patients in the 2 groups. However, the incidence of postoperative meningitis was higher in the Drain group than in the No Drain group (9.09% vs. 1.59%, P = 0.009), and the total length of stay and postoperative length of stay in the Drain group were also more extended than in the No Drain group (17.32 ± 6.45 vs. 14.43 ± 5.75, P = 0.005; 12.83 ± 5.07 vs. 9.82 ± 4.50, P = 0.007, respectively). CONCLUSIONS: Postoperative wound drain did not significantly reduce the incidence of an extradural hematoma after anterior circulation aneurysm surgery. On the contrary, it may be associated with an increased incidence of postoperative meningitis and length of stay. Given these findings, the postoperative drain should be maintained cautiously and meet more rigorous application criteria.

Racial Disparities Affecting Postoperative Outcomes After Brain Tumor Resection.

OBJECTIVE: To investigate racial disparities in 30-day postoperative outcomes of craniotomy for glioma resection. METHODS: 2006-2019 American College of Surgeons' National Surgical Quality Improvement Program files were queried for all patients who underwent a craniotomy for a supratentorial glioma resection. Racial disparities in preoperative variables were studied between the demographic cohorts of Asian, African Americans, Hispanics, and Caucasian. Fisher exact tests were used to examine association of preoperative variables with race. Multivariable logistic regression models, adjusted for all preoperative variables associated with race, were used to determine the odds ratios of postoperative outcomes for each demographic cohort in comparison with Caucasian patients. RESULTS: A total of 12,544 patients were identified: 4% Asian, 5% African American, 7% Hispanic, and 85% Caucasian. African American patients had significantly higher adjusted odds than Caucasian patients of major adverse cardiovascular events (adjusted odds ratio [aOR]: 1.827, 95% confidence interval [CI]: 1.155-2.891, P = 0.01), pulmonary events (aOR: 1.683, 95% CI: 1.145-2.473, P = 0.008), and urinary tract infection (aOR: 2.016, 95% CI: 1.221-3.327, P = 0.006). Asian patients had significantly higher odds than Caucasian patients of requiring a transfusion (aOR: 2.094, 95% CI: 1.343-3.266, P = 0.001). All demographic cohorts had higher odds of having an extended length of stay than Caucasian patients. CONCLUSIONS: African American patients who undergo a craniotomy for glioma resection have almost twice the odds of Caucasian patients of having a postoperative major cardiovascular complication, pulmonary complication, or urinary tract infection. All minority groups have higher odds of an extended length of stay as compared with Caucasian patients.

Imaging Pattern and the Mechanisms of Postoperative Infarction After Indirect Revascularization in Patients with Moyamoya Disease.

OBJECTIVE: To develop preventive strategies against postoperative infarction after indirect revascularization surgery in patients with moyamoya disease (MMD), we evaluated clinical information, with a specific focus on the imaging pattern of postoperative infarction. METHODS: We retrospectively evaluated 421 surgical procedures performed in 354 (262 pediatric and 159 adult) patients with MMD from April 1991 to March 2021 at our institute. In addition to clinical information, raw images of postoperative infarction were collected and categorized into subtypes by the location of the infarction. RESULTS: Symptomatic and asymptomatic postoperative infarction occurred in 47 and 12 patients (11.1% and 2.6%), respectively, and more than half (51.7%) of these cases of postoperative infarction occurred immediately or the day after the surgery. Cortical infarction around the craniotomy site was the most frequent pattern observed (50/59, 84.8%), and some of these cases seemed to occur under local compression from epidural or subdural hematomas (15/50, 30.0%). Ipsilateral white matter infarctions located in the watershed area (9/59, 15.3%) and contralateral infarctions (3/59, 5.1%) were also observed. Four patients (1.0%) showed sudden occlusions of ipsilateral or contralateral large intracranial arteries immediately after surgery. Postoperative infarction caused permanent neurologic deficits in 7 patients (1.7%), and all included the cortex outside the craniotomy site. CONCLUSIONS: Local cortical irritation, hemodynamic fluctuation, and thromboembolic events were suggested as possible mechanisms of postoperative infarction after indirect revascularization in patients with MMD. Minimizing cortical irritation, maintaining adequate cerebral blood flow, and perioperative antiplatelet agents might decrease the incidence of postoperative infarction.

Management of chronic subdural hematoma with the subdural evacuating port system: Systematic review and meta-analysis.

The subdural evacuating port system (SEPS) is a minimally invasive option for treating chronic subdural hematoma (cSDH). Individual case series have shown it to be safe and effective, but outcomes have not been systematically reviewed. We sought to review the literature in order to determine the safety and efficacy of SEPS as a first line treatment for cSDH. A comprehensive literature search for outcomes following SEPS placement as a primary treatment for cSDH was performed. The primary outcome was treatment success, which was defined as a composite of improvement in presenting symptoms and no need for further treatment in the operating room. Additional outcomes included discharge disposition, length of stay (LOS), hematoma recurrence, and complications. A total of 12 studies comprising 953 patients who underwent SEPS placement met the inclusion criteria. The pooled rate of a successful outcome was 0.79 (95% CI 0.75-0.83). Frequency of delayed hematoma recurrence was 0.15 (95% CI 0.10-0.21). The pooled inpatient mortality rate was 0.02 (95% CI 0.01-0.03). Complications rates included 0.02 (95% CI 0.00-0.03) for any acute hemorrhage, 0.01 (95% CI 0.00-0.01) for acute hemorrhage requiring surgery, and 0.02 (95% CI 0.01-0.03) for seizure. SEPS placement is associated with a success rate of 79% and very low rates of acute hemorrhage and seizure. This data supports its use as a first-line management strategy, although prospective randomized studies are needed.

Minimally invasive puncture versus conventional craniotomy for spontaneous supratentorial hemorrhage: A meta-analysis.

BACKGROUND: Minimally invasive puncture and conventional craniotomy are both utilized in the treatment of spontaneous supratentorial hemorrhage. The purpose of this study is to review evidence that compares the safety and effectiveness of these two techniques. METHODS: We searched EMBASE, Cochrane Library, Web of Science, and PubMed for studies published between 2000 and 2019 that compared the minimally invasive puncture procedure with the conventional craniotomy for the treatment of spontaneous supratentorial hemorrhage. RESULTS: Seven trials (2 randomized control trials and 5 observational studies) with a total of 970 patients were included. The odds ratio indicated a statistically significant difference between the minimally invasive puncture and conventional craniotomy in terms of good functional outcome (OR 2.36, 90% CI 1.24-4.49). The minimally invasive puncture procedure was associated with lower mortality rates (OR 0.61, 90% CI 0.44-0.85) and rebleeding rates (OR 0.48, 95%CI 0.24-0.99; P=0.003). CONCLUSIONS: The use of the minimally invasive puncture for the management of spontaneous supratentorial hemorrhage was associated with better functional outcome results, a lower mortality rate, and decreased rebleeding rates. However, because insufficient data has been published thus far, we need more robust evidence to provide a better guide for future management.

Quality of life and olfactory function after suprasellar craniopharyngioma surgery-a single-center experience comparing transcranial and endoscopic endonasal approaches.

The endoscopic endonasal approach to suprasellar craniopharyngiomas has become popular as alternative to transcranial approaches. However, the literature lacks data regarding quality of life and olfactory function. The assessment of the long-term quality of life and olfactory function of all patients harboring a suprasellar craniopharyngioma who underwent surgery in our department has been done. Patient characteristics and perioperative data were gathered in a prospectively maintained database. At the last follow-up visit, the olfactory function and the quality of life (ASBQ, SNOT-22) as well as visual and pituitary function were assessed. Thirteen and 17 patients underwent surgery via a transcranial (T) and endonasal (E) route, respectively. No differences were seen in ASBQ, SNOT-22, and olfactory function between T and E, but in E were more full-time worker and less obesity. CSF leaks occurred in 15% of T and 29% of E (p = 0.43). Patients from group E had a superior visual outcome which was most pronounced in the visual field. The degree of new anterior and posterior pituitary gland deficiency after surgery and in the follow-up was lower in group E. The general and sinonasal quality of life and the olfactory function are equal in E and T. E is associated with a superior visual outcome, lower rates of diabetes insipidus, and lower rates of obesity, but has a higher risk for postoperative CSF leaks.

Risk factors for wound-related complications after microvascular decompression.

Retrosigmoid craniotomy for microvascular decompression (MVD) has been traditionally performed via craniectomy. Various closure techniques have been described, yet factors associated with wound-related complications remain undetermined. Accordingly, herein, we sought to identify risk factors associated with wound-related complications after such procedures. An institutional retrospective case-control study was performed; outcomes of interest were cerebrospinal fluid (CSF) leak, wound dehiscence, wound infection, and pseudomeningocele. Univariate analysis was performed using Wilcoxon rank sum test for non-parametric continuous outcomes and chi-square test for categorical outcomes. Multivariate logistic regression was performed on binomial outcome variables. The study population included 197 patients who underwent MVD for trigeminal neuralgia (83.2%), hemifacial spasm (12.2%), vestibular nerve section (3.0%), and glossopharyngeal neuralgia (1.5%). The overall wound-related complication rate was 14.2% (n = 28), including twelve patients (6.1%) with CSF leak, ten patients (5.1%) with wound infection, ten patients (5.1%) with pseudomeningocele, and nine (4.6%) patients with wound dehiscence. Using multivariate logistic regression, preoperative anemia and current tobacco use were associated with significantly higher rates of complications (OR 6.01 and 4.58, respectively; p < 0.05), including CSF leak (OR 12.83 and 12.40, respectively, p < 0.05). Of note, use of synthetic bone substitute for cranioplasty was associated with a significantly lower rate of complications (OR 0.13, p < 0.01). Preoperative anemia and current tobacco use significantly increased, while synthetic bone substitute cranioplasty significantly decreased, odds of wound-related complications, the need for treatment, and CSF leaks. Additionally, higher BMI, longer operative duration, and prior radiosurgery may increase risk for wound-related complications.

Alterations in Functional Connectomics Associated With Neurocognitive Changes Following Glioma Resection.

BACKGROUND: Decline in neurocognitive functioning (NCF) often occurs following brain tumor resection. Functional connectomics have shown how neurologic insults disrupt cerebral networks underlying NCF, though studies involving patients with brain tumors are lacking. OBJECTIVE: To investigate the impact of brain tumor resection upon the connectome and relationships with NCF outcome in the early postoperative period. METHODS: A total of 15 right-handed adults with left perisylvian glioma underwent resting-state functional magnetic resonance imaging (rs-fMRI) and neuropsychological assessment before and after awake tumor resection. Graph theoretical analysis was applied to rs-fMRI connectivity matrices to calculate network properties. Network properties and NCF measures were compared across the pre- to postoperative periods with matched pairs Wilcoxon signed-rank tests. Associations between pre- to postoperative change in network and NCF measures were determined with Spearman rank-order correlations (ρ). RESULTS: A majority of the sample showed postoperative decline on 1 or more NCF measures. Significant postoperative NCF decline was found across measures of verbal memory, processing speed, executive functioning, receptive language, and a composite index. Regarding connectomic properties, betweenness centrality and assortativity were significantly smaller postoperatively, and reductions in these measures were associated with better NCF outcomes. Significant inverse associations (ρ = -.51 to -.78, all P < .05) were observed between change in language, executive functioning, and learning and memory, and alterations in segregation, centrality, and resilience network properties. CONCLUSION: Decline in NCF was common shortly following resection of glioma involving eloquent brain regions, most frequently in verbal learning/memory and executive functioning. Better postoperative outcomes accompanied reductions in centrality and resilience connectomic measures.

Tuberculum sellae meningioma surgery: visual outcomes and surgical aspects of contralateral approach.

The main purpose of surgery for tuberculum sellae meningioma (TSM) is the improvement and/or stabilization of patients' visual function. Options for the side of lateral approaches usually were restricted for nondominant right-sided craniotomy or to the side of impaired vision (ipsilateral approaches). Although the safety and effectiveness of ipsilateral transcranial approach was proved, there are some doubts and discussions about the contralateral craniotomy. We retrospectively analyzed the series of contralateral surgeries of TMS and their visual outcomes comparing with ipsilateral approach. Twenty-six patients with TSM were operated on from 2010 to 2019 (F/M 20/6, mean age 49 years), in 17 (65%) we performed contralateral and in 9 (35%) ipsilateral approach. All procedures were performed via fronto-lateral craniotomy. Gross total resection (GTR) was achieved in 21 (81%) cases and in all but one patient we noticed visual improvement after surgery (96%). Optic canal unroofing with mobilization of more affected visual nerve was necessary in 5/9 pts of ipsilateral vs 3/17 pts of contralateral group. We had no significant postoperative complications.There was no difference in outcome between ipsilateral and contralateral fronto-lateral approaches for TSM resection; thus, contralateral approach was at least as safe and effective as ipsilateral.

Outcome prediction in brain tumor surgery: a literature review on the influence of nonmedical factors.

The purpose of the present study was to review the existing data on preoperative nonmedical factors that are predictive of outcome in brain tumor surgery. Our hypothesis was that also the individual characteristics (e.g., emotional state, cognitive status, social relationships) could influence the postoperative course in addition to clinical factors usually investigated in brain tumor surgery. PubMed, Embase, and Scopus were searched from 2008 to 2018 using terms relating to brain tumors, craniotomy, and predictors. All types of outcome were considered: clinical, cognitive, and psychological. Out of 6.288 records identified, 16 articles were selected for analysis and a qualitative synthesis of the prognostic factors was performed. The following nonmedical factors were found to be predictive of surgical outcomes: socio-demographic (age, marital status, type of insurance, gender, socio-economic status, type of hospital), cognitive (preoperative language and cognitive deficits, performance at TMT-B test), and psychological (preoperative depressive symptoms, personality traits, autonomy for daily activities, altered mental status). This review showed that nonmedical predictors of outcome exist in brain tumor surgery. Consequently, individual characteristics (e.g., emotional state, cognitive status, social relationships) can influence the postoperative course in addition to clinical factors.

Timing of cranial reconstruction after cranioplasty infections: are we ready for a re-thinking? A comparative analysis of delayed versus immediate cranioplasty after debridement in a series of 48 patients.

The optimal management of cranioplasty infections remains a matter of debate. Most authors have suggested that the infected bone/implant removal is mandatory, combined with prolonged antibiotic therapy before reconstruction. However, failures can occur, even with 12-18-month intervals between the surgeries. Longer wait times before cranial reconstruction increase the risks of socioeconomic burdens and further complications, as observed in decompressed patients hosting shunts. In our department, we treated 48 cranioplasty infections over a period of 8 years, divided into two groups. For Group A (n = 26), the treatment consisted of cranioplasty removal and debridement, followed by a delayed reconstruction. Group B (n = 22) received 2 weeks of broad-spectrum antibiotics, followed by an "aggressive" field debridement and immediate cranioplasty. All patients received a minimum of 8 weeks of post-operative antibiotic therapy and were scheduled for clinic-radiological follow-ups for at least 36 months. Significant differences were observed between Groups A and B with respect to the number of failures (respectively 7 versus 1), the global operative time (significantly longer for Group B), germ identification (respectively 7 versus 13), and the overall length of hospital stay (on average, 61.04 days in Group A versus 47.41 days in Group B). Three shunted patients in Group A developed sinking flap syndrome. Shunt resetting allowed symptom control until cranioplasty in one subject, whereas two did not improve, even after reconstruction. In selected patients, an aggressive field debridement, followed by the immediate replacement of an infected cranioplasty, may represent a safe and valuable option.

Surgical outcomes of Supra- Infra Tentorial Extradural Hematoma (SIEDH): A retrospective study from a single institution.

INTRODUCTION: Bicompartmental Supra plus Infratentorial Extra Dural Hematoma (SIEDH) is an uncommon yet important category of Extradural Hematoma (EDH) straddling the transverse sinus. It requires quick decision making and proper surgical evacuation. METHODS: We did a retrospective chart review of all SIEDH cases from prospectively maintained operative database in our institute between 2011 & 2017. Clinical status at discharge and follow up were used to assess outcome. Ordinal regression analysis was used for analysis of factors predicting the outcome. We also describe the surgical procedure we follow at our high-volume trauma center for this unique entity. RESULTS: We had 61 operated cases of SIEDH in our series. The median age of the cohort was 30 years (IQR: 21.5-42). Road Traffic Accident was the most common mode of injury (67.2 %). Median pre-operative GCS was 12 (IQR: 9-12). The median volume of SIEDH was 50cc (IQR: 40-70). Mass effect on 4thventricle and brainstem was seen in 47 and 34 patients respectively. An associated fracture was seen in 54 patients. Sinus injury related bleed was noted intra-operatively in 57 % (N = 35). Follow up was available for 60 cases with a median of 130 days. On evaluating with ordinal regression analysis, we found that, the GCS at presentation, pupillary asymmetry, volume of SIEDH, infratentorial volume, blood loss and mass effect on 4thventricle were statistically significant factors affecting GCS at discharge. However, the GCS at presentation, infratentorial volume and blood loss were the only factors determining GOS at follow-up. CONCLUSION: SIEDH are uncommon yet important type of injury type which requires prompt attention and appropriate nuanced approach. Large SIEDH are commonly associated with sinus injury, and large volume blood loss may be anticipated. In addition, SIEDH may be associated with other traumatic brain injuries which may require surgical evacuation.

Tobacco Use Is Associated with Readmission within 90 Days after Craniotomy.

OBJECTIVE: Tobacco use increases morbidity and mortality following craniotomy. Readmission is an important hospital metric of patient outcomes and has been used to inform reimbursement. This study aims to determine if tobacco use is associated with readmission within 90 days of hospital discharge among patients undergoing elective craniotomy. METHODS: The Nationwide Readmissions Database (NRD), a population-based, nationally representative database, was queried from 2010-2014. Patients undergoing craniotomy for benign or malignant tumors, vascular pathologies, and epilepsy were identified. Readmissions within 90 days of index hospitalization were characterized by admitting diagnoses. Tobacco use was defined by ICD-9 coding for active or prior use. Descriptive and multivariable regression analyses evaluated patient and hospital factors associated with readmission. RESULTS: The study population included 77,903 patients treated with craniotomy. Of these, 17,674 (22.6%) were readmitted within 90 days. The most common reasons for readmission were post-operative infection (5.8%), septicemia (4.2%), pulmonary embolism (3.9%), and pneumonia (2.9%). Tobacco use was associated with a 7% increased likelihood of 90-day readmission (OR 1.07, 95% CI 1.03-1.11, p = 0.0008) after accounting for other patient-, disease-, and hospital-level factors in multivariate analysis. CONCLUSIONS: Tobacco use was associated with increased 90-day readmission in patients undergoing craniotomy. Recognizing tobacco use as a modifiable risk factor of readmission presents an opportunity to identify susceptible patients.

Transcranial approach for pituitary adenomas - An evaluation of surgical approaches over two decades and factors influencing peri-operative morbidity.

PURPOSE: Transcranial surgery(TCS) for pituitary adenoma(PA) is mostly reserved for lesions with widespread extensions. We sought to analyse the intraoperative challenges, morbidity and the factors associated with morbidity of transcranial approaches, in a large series from a tertiary neurosurgical institute. METHODS: We retrospectively evaluated 137 patients who underwent TCS for PA in our institute. The details of their clinical features, imaging, operative and peri-operative events and complications were collected and analysed. The factors associated with morbidity were evaluated. RESULTS: The mean age of the cohort was 40.86 ± 13.35 years. 21 (15.3%) patients developed significant post-operative hematoma, out of which 7 patients (5.1%) required re-exploration. Post-operative diabetes insipidus was noted in 45 patients (32.84%), while SIADH was noted in 10 patients (7.35%). Other complications were cranial nerve palsy in 14 patients (10.2%), visual deterioration in 7 patients (5.1%). Neither tumour characteristics nor the choice of approach was associated with occurrence of post op hematoma. SIADH was significantly associated with patients with tumours involving cavernous sinus (p = 0.019) and subfrontal extension (p = 0.031). Patients with post-operative hematoma had significantly higher incidence of post-op DI (57.1% vs 28.7%; p = 0.021), while similar correlation was not noticed with SIADH (4.7 vs 7.8%). CONCLUSION: TCS plays a distinct, albeit a small role in surgical management of pituitary adenoma. Tumour related or approach related factors are not significantly associated with the incidence of hematoma. Post-operative hematoma significantly influences the incidence of DI. A proper and judicious selection of approach and meticulous surgical technique should result in a reduction in associated morbidity and mortality.

The Glasgow Outcome Scale-Extended Pediatric Scores of Intracranial Bleeding Patients with Acquired Prothrombin Complex Deficiency Post Craniotomy and Duraplasty.

INTRODUCTION: Surgical evacuation of intracranial bleeding in pediatric patients due to acquired prothrombin complex deficiency (APCD) is a life-saving surgery when conservative treatment insufficient and impending brain herniation. This study aimed to evaluate the Glasgow outcome scale-extended pediatric (GOS-ePed) score of the pediatric intracranial bleeding patients with APCD after craniotomy and duraplasty. METHOD: This was a retrospective study in the last 5 years of our experience. All of the pediatric patients with intracranial bleeding due to APCD who needed surgery were investigated. The data were collected from medical records after their parents have given their written informed concern and approved by the Ethics Review Committee, Faculty of Medicine, Universitas Kristen Indonesia. The inclusion criteria were patients who operated on by craniotomy and duraplasty. The patient with a second disease was excluded. Blood tests include hemoglobin, prothrombin time, activated prothrombin time, and platelets were investigated before and after intravenous vitamin K injection, transfusion packed red cells (PRCs), and fresh frozen plasma (FFP) administration. The Glasgow coma scale (GCS) pre- and postoperatively was evaluated using a modified GCS for infants and children. The outcome was evaluated by the GOS-ePed score. All data were analyzed with the normality test and paired t test. RESULTS: There were 5 patients age between 37 and 60 days, and all patients did not get vitamin K prophylaxis after birth. The blood tests of all patients revealed anemia, prothrombin, and activated prothrombin time increased, but platelets were normal. All these values returned to normal after vitamin K injection, transfusion of PRCs, and FFP. The paired t tests were p < 0.05. The GCS of all patients before surgery was 8 or below. After surgery, the GCS of 4 patients was increased become 12 and 15. One patient did not change significantly. The GOS-ePed score showed 4 patients (80%) had upper or lower good recovery, and 1 patient (20%) was in a vegetative state. CONCLUSIONS: The GOS-ePed score of the pediatric intracranial bleeding with APCD after craniotomy and duraplasty was mostly in upper or lower good recovery.

Frailty and outcomes after craniotomy for brain tumor.

Frailty has been associated with increased morbidity and mortality in a variety of surgical disciplines. Few data exist regarding the relationship of frailty with adverse outcomes in craniotomy for brain tumor resection. We assessed the relationship between frailty and the incidence of major post-operative complication, discharge destination other than home, 30-day readmission, and 30-day mortality after elective craniotomy for brain tumor resection. A retrospective cohort study was conducted on 20,333 adult patients undergoing elective craniotomy for tumor resection in the 2012-2018 ACS-NSQIP Participant Use File. Multivariate logistic regression was performed using all covariates deemed eligible through clinical and statistical significance. 6,249 patients (30.7%) were low-frailty and 2,148 patients (10.6%) were medium-to-high frailty. In multivariate logistic regression adjusting for age, gender, BMI, ASA classification, smoking status, dyspnea, significant pre-operative weight loss, chronic steroid use, bleeding disorder, tumor type, and operative time, low frailty was associated with increased adjusted odds ratio of major complication (1.41, 95% CI: 1.23-1.60, p < 0.001), discharge destination other than home (1.32, 95% CI: 1.20-1.46, p < 0.001), 30-day readmission (1.29, 95% CI: 1.15-1.44, p < 0.001), and 30-day mortality (1.87, 95% CI: 1.41-2.47, p < 0.001). Moderate-to-high frailty was also associated with increased adjusted odds of major complication (1.61, 95% CI: 1.35-1.92, p < 0.001), discharge destination other than home (1.80, 95% CI: 1.58-2.05), 30-day readmission (1.39, 95% CI: 1.19-1.62, p < 0.001), and 30-day mortality (2.42, 95% CI: 1.74-3.38, p < 0.001). CONCLUSIONS: Frailty is associated with increased odds of major post-operative complication, discharge to destination other than home, 30-day readmission, and 30-day mortality.

Predictors of an Extended Length of Stay following an Elective Craniotomy in Children and Young Adults.

BACKGROUND: Length of stay (LOS) is now a generally accepted clinical metric within the USA. An extended LOS following an elective craniotomy can significantly impact overall costs. Few studies have evaluated predictors of an extended LOS in pediatric neurosurgical patients. OBJECTIVE: The aim of the study was to determine predictors of an extended hospital LOS following an elective craniotomy in children and young adults. METHODS: All pediatric patients and young adults undergoing an elective craniotomy between January 1, 2010, and April 1, 2019, were retrospectively identified using a prospectively maintained database. Demographic, clinical, radiological, and surgical data were collected. The primary outcome was extended LOS, defined as a postsurgical stay greater than 7 days. Bivariate and multivariable analyses were performed. RESULTS: A total of 1,498 patients underwent 1,720 elective craniotomies during the study period over the course of 1,698 hospitalizations with a median LOS of 4 days (interquartile range 3-6 days). Of these encounters, 218 (12.8%) had a prolonged LOS. Multivariable analysis demonstrated that non-Caucasian race (OR = 1.9 [African American]; OR = 1.6 [other]), the presence of an existing shunt (OR = 1.8), the type of craniotomy (OR = 0.3 [vascular relative to Chiari]), and the presence of a postoperative complication (OR = 14.7) were associated with an extended LOS. CONCLUSIONS: Inherent and modifiable factors predict a hospital stay of more than a week in children and young adults undergoing an elective craniotomy.
