Clinical Outcomes in Elderly Patients with Chronic Subdural Hematoma: Validation of Irrigation Assignment Based on Hematoma Characteristics. Life (Basel) 2024; 14:518. [PMID: 38672788 PMCID: PMC11051316 DOI: 10.3390/life14040518] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/13/2024] [Revised: 04/13/2024] [Accepted: 04/14/2024] [Indexed: 04/28/2024] Open
Abstract
The number of elderly patients with chronic subdural hematomas (CSDH) is increasing worldwide; however, there is limited data regarding the clinical outcomes in this population. Our therapeutic method using burr hole evacuation for CSDH is based on the hematoma characteristics, using simple drainage for single-layer lesions and drainage with irrigation for multiple-layer lesions. This study aimed to compare the postoperative outcomes of elderly and younger patients, identify the predictors of outcomes in elderly patients, and verify the validity of our therapeutic methods. In total, we included 214 patients who underwent burr hole evacuation between April 2018 and March 2022. Baseline characteristics, hematoma characteristics, recurrence, and clinical outcomes were compared between the elderly and younger patients. Overall, 96 elderly patients (44.9%) were included in the study, and more elderly patients underwent antithrombotic therapy than younger patients (33.3% vs. 19.5%, p = 0.027). Moreover, elderly patients had significantly fewer favorable outcomes than younger patients (70.8% vs. 91.5%; p < 0.001); however, this was not significant after adjusting for the baseline modified Rankin Scale (mRS). Similarly, elderly patients had higher recurrence rates than younger patients (10.4% vs. 2.5%; p = 0.021). However, the baseline mRS score was the only predictor of unfavorable outcomes. In conclusion, although the clinical outcomes of elderly patients were comparable to those of younger patients, the higher rate of preoperative antithrombotic therapy in elderly patients may result in a higher rate of recurrence requiring a long-term follow-up.

Extreme-aged patients (≥ 85 years) experience similar outcomes as younger geriatric patients following chronic subdural hematoma evacuation: a matched cohort study. GeroScience 2024:10.1007/s11357-024-01081-8. [PMID: 38286851 DOI: 10.1007/s11357-024-01081-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/05/2023] [Accepted: 01/12/2024] [Indexed: 01/31/2024] Open
Abstract
Subdural hematoma (SDH) evacuation represents one of the most frequently performed neurosurgical procedures. Several reports cite a rise in both the age and number of patient's requiring treatment, due in part to an aging population and expanded anticoagulation use. However, limited data and conflicting conclusions exist on extreme-aged geriatric patients (≥ 85 years of age) after undergoing surgery. Patients undergoing SDH evacuation at a tertiary academic medical center between November 2013-December 2021 were retrospectively identified. The study group consisted of patients ≥ 85 years (Group 1) diagnosed with a chronic SDH surgically evacuated. A control group was created matching patients by 70-84 years of age, gender, and anticoagulation use (Group 2). Multiple metrics were evaluated between the two including length-of hospital-stay, tracheostomy/PEG placement, reoperation rate, complications, discharge location, neurological outcome at the time of discharge, and survival. A total of 130 patients were included; 65 in Group 1 and 65 in Group 2. Patient demographics, medical comorbidities, SDH characteristics, international normalized ratio, partial thromboplastin time, and use of blood thinning agents were similar between the two groups. Kaplan Meier survival analysis at one-year was 80% for Group 1 and 76% for Group 2. No significant difference was identified using the log-rank test for equality of survivor functions (p = 0.26). All measured outcomes including GCS at time of discharge, length of stay, rate of reoperations, and neurological outcome were statistically similar between the two groups. Backwards stepwise conditional logistic regression revealed no significant association between poor outcomes at the time of discharge and age. Alternatively, anticoagulation use was found to be associated with poor outcomes (OR 3.55, 95% CI 1.08-11.60; p = 0.036). Several outcome metrics and statistical analyses were used to compare patients ≥ 85 years of age to younger geriatric patients (70-84 years) in a matched cohort study. Adjusting for age group, gender, and anticoagulation use, no significant difference was found between the two groups including neurological outcome at discharge, reoperation rate, and survival.

The Utility of the 5 Factor Modified Frailty Index in Outcome Prediction for Patients with Chronic Subdural Hematoma Treated with Surgical Drainage. World Neurosurg 2023; 179:e328-e341. [PMID: 37634666 DOI: 10.1016/j.wneu.2023.08.085] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Accepted: 08/19/2023] [Indexed: 08/29/2023]
Abstract
OBJECTIVE Increasing frailty is a significant determinant of perioperative morbidity and mortality within neurosurgical literature. This study investigates the predictive value of the modified frailty index 5 (mFI-5) for postoperative morbidity and mortality following surgical drainage of chronic subdural hematoma (cSDH). METHODS A retrospective cohort study was performed on patients who underwent surgical evacuation of a cSDH. The mFI-5 score was calculated for each patient and used to stratify patients: prefrail (mFI-5<2), frail (mFI-5 = 2), and severely frail (mFI-5>2). Multivariate Cox proportional hazards (CPH) regression analysis were used to identify factors associated with our primary outcomes: overall survival and 30-day readmission. Secondary outcomes included nonhome discharge, length of stay, hematoma accumulation, development of new postoperative neurologic deficits, resolution of preoperative neurologic deficits, and a modified Rankin score >2 at discharge. RESULTS 118 patients with a mean age of 74.4 ± 11.9 years were analyzed. All baseline demographics were similar across the 3 groups. On multivariate analysis, severely frail patients (N = 24, 20.3%) had increased rates of 30-day readmission (hazard ratio [HR] 4.3, CPH regression P value<0.001) and postoperative mortality (HR 3.1, CPH regression P value<0.01) compared to the prefrail cohort. Severely frail patients had increased rates of nonhome disposition (HR 9.6, CPH regression P value< 0.001), development of new postoperative neurologic deficits (HR 2.75, CPH regression P value = 0.03), and hematoma reaccumulation (HR 4.07, CPH regression P value = 0.004). A novel scoring system accounting for patient age and frailty was predictive of 90-day mortality (area under the curve 0.77). CONCLUSIONS Frailty, measured by the mFI-5, and our novel scoring system hold a predictive value regarding outcomes for patients undergoing surgical drainage of a cSDH.

Surgical techniques for evacuation of chronic subdural hematoma: a mini-review. Front Neurol 2023; 14:1086645. [PMID: 37456631 PMCID: PMC10338715 DOI: 10.3389/fneur.2023.1086645] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/01/2022] [Accepted: 05/30/2023] [Indexed: 07/18/2023] Open
Abstract
Chronic subdural hematoma is one of the most common neurosurgical pathologies with over 160,000 cases in the United States and Europe each year. The current standard of care involves surgically evacuating the hematoma through a cranial opening, however, varied patient risk profiles, a significant recurrence rate, and increasing financial burden have sparked innovation in the field. This mini-review provides a brief overview of currently used evacuation techniques, including emerging adjuncts such as endoscopic assistance and middle meningeal artery embolization. This review synthesizes the body of available evidence on efficacy and risk profiles for each critical aspect of surgical technique in cSDH evacuation and provides insight into trends in the field and promising new technologies.

Subdural evacuating port system with subdural thrombolysis for the treatment of chronic subdural hematoma in patients older than 80 years. Front Neurol 2023; 14:1068829. [PMID: 36873430 PMCID: PMC9975157 DOI: 10.3389/fneur.2023.1068829] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/13/2022] [Accepted: 01/17/2023] [Indexed: 02/17/2023] Open
Abstract
Objective The subdural evacuating port system (SEPS) is a minimally invasive approach that can be performed under local anesthesia for the treatment of chronic subdural hematoma (CSDH). Subdural thrombolysis has been described as an exhaustive drainage strategy and found to be safe and effective for improving drainage. We aim to analyze the effectiveness of SEPS with subdural thrombolysis in patients older than 80 years. Method Consecutive patients aged ≥80 years old who presented with symptomatic CSDH and underwent SEPS followed by subdural thrombolysis between January 2014 and February 2021 were retrospectively studied. Outcome measures included complications, mortality, recurrence, and modified Rankin Scale (mRS) scores at discharge and 3 months. Results In total, 52 patients with CSDH in 57 hemispheres were operated on, with a mean age of 83.9 ± 3.3 years, and 40 (76.9%) patients were men. The preexisting medical comorbidities were observed in 39 patients (75.0%). Postoperative complications occurred in nine patients (17.3%), with two having significant complications (3.8%). The complications observed included pneumonia (11.5%), acute epidural hematoma (3.8%), and ischemic stroke (3.8%). One patient experienced contralateral malignant middle cerebral artery infarction and died of subsequent severe herniation, contributing to a perioperative mortality rate of 1.9%. Discharge and 3 months of favorable outcomes (mRS score 0-3) were achieved in 86.5% and 92.3% of patients, respectively. CSDH recurrence was observed in five patients (9.6%), and repeat SEPS was performed. Conclusion As an exhaustive drainage strategy, SEPS followed by thrombolysis is safe and effective with excellent outcomes among elderly patients. It is a technically easy and less invasive procedure with similar complications, mortality, and recurrence rates compared with burr-hole drainage in the literature.

Anti-Inflammatory Drug Therapy in Chronic Subdural Hematoma: A Systematic Review and Meta-Analysis of Prospective Randomized, Double-Blind and Placebo-Controlled Trials. Int J Mol Sci 2022; 23:ijms232416198. [PMID: 36555838 PMCID: PMC9784956 DOI: 10.3390/ijms232416198] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2022] [Revised: 12/12/2022] [Accepted: 12/16/2022] [Indexed: 12/23/2022] Open
Abstract
Althoughanti-inflammatory drug therapy has been identified as potentially beneficial for patients suffering from chronic subdural hematoma (cSDH), contemporary literature presents contradictory results. In this meta-analysis, we aimed to investigate the impact of anti-inflammatory drug therapy on mortality and outcome. We searched for eligible randomized, placebo-controlled prospective trials (RTCs) on PubMed, Embase and Medline until July 2022. From 97 initially identified articles, five RTCs met the criteria and were included in our meta-analysis. Our results illustrate significantly lower rates of recurrent cSDH (OR: 0.35; 95% CI: 0.21-0.58, p = 0.0001) in patients undergoing anti-inflammatory therapy. In the subgroup of patients undergoing primary conservative treatment, anti-inflammatory therapy was associated with lower rates of "switch to surgery" cases (OR: 0.30; 95% CI: 0.14-0.63, p = 0.002). Despite these findings, anti-inflammatory drugs seemed to be associated with higher mortality rates in patients undergoing surgery (OR: 1.76; 95% CI: 1.03-3.01, p = 0.04), although in the case of primary conservative treatment, no effect on mortality has been observed (OR: 2.45; 95% CI: 0.35-17.15, p = 0.37). Further multicentric prospective randomized trials are needed to evaluate anti-inflammatory drugs as potentially suitable therapy for asymptomatic patients with cSDH to avoid the necessity of surgical hematoma evacuation on what are predominantly elderly, vulnerable, patients.

Expert consensus on drug treatment of chronic subdural hematoma. Chin Neurosurg J 2021; 7:47. [PMID: 34809712 PMCID: PMC8607705 DOI: 10.1186/s41016-021-00263-z] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/13/2021] [Accepted: 09/22/2021] [Indexed: 11/10/2022] Open
Abstract
Chronic subdural hematoma (CSDH) is a chronic space-occupying lesion formed by blood accumulation between arachnoid and dura mater, which is usually formed in the third week after traumatic brain injury. Surgical treatment is usually the first choice for patients with CSDH having a significant space-occupying effect. Most of the patients showed good results of surgical treatment, but still some patients had a postoperative recurrence (the recurrence rate was up to 33%). Because CSDH is often seen in the elderly, patients are weak and have many basic diseases. The risk of surgical treatment is high; serious complications and even death (the death rate is up to 32%) can often occur. The overall good prognosis rate of patients aged more than 90 years is 24%. The drug treatment can provide a safe and effective treatment for elderly patients who are weak, intolerable to surgery, or failed in surgery. Low-dose and long-term use of atorvastatin (20mg/d) is suggested for continuous treatment for at least 8 weeks, while low-dose and short-term use of dexamethasone can improve the therapeutic effect of atorvastatin on CSDH. Patients should undergo CT or MRI scanning at least one time within 2 weeks after the start of drug treatment.

Surgical Management of Chronic Subdural Hematoma in Older Adults: A Systematic Review. J Gerontol A Biol Sci Med Sci 2021; 76:1454-1462. [PMID: 33220683 DOI: 10.1093/gerona/glaa293] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Indexed: 02/05/2023] Open
Abstract
BACKGROUND Chronic subdural hematoma (cSDH) is a form of intracranial hemorrhage common in older adults. Optimal treatment remains controversial. We conducted a systematic review to identify surgical thresholds, characterize outcomes, and delineate critical considerations in the surgical management of older adults in order to summarize the evidence supporting the best contemporary management of cSDH. METHODS A systematic review exploring surgical management of cSDH among individuals aged 65 years and older was conducting by searching the PubMed, Embase, and Scopus databases for articles in English. Abstracts from articles were read and selected for full-text review according to a priori criteria. Relevant full-text articles were analyzed for bibliographic data, aim, study design, population, interventions, and outcomes. RESULTS Of 1473 resultant articles, 21 were included. Surgery rationale was case-by-case for symptomatic patients with cSDH. Surgery was superior to conservative management and promoted equivalent neurologic outcomes and rates of complications. Recurrence and reoperation rates in older adults were similar to younger individuals. Some studies reported higher mortality rates for older adults, while others reported no difference. Anticoagulation or antiplatelet agent use did not seem to be associated with poorer outcomes in older adults. CONCLUSIONS Surgery for cSDH in older adults leads to favorable neurologic outcomes without increased risk of overall complications, recurrence, or reoperation compared to younger patients. However, older adults may be at increased risk for mortality after surgery. It is important to determine use of anticoagulant or antiplatelet agents in older adults to optimally manage patients with cSDH.

Abstract
Antecedentes:
El hematoma subdural crónico (HSDC) es una patología ampliamente estudiada, muy frecuente, sobre todo en adultos mayores; su cuadro clínico tiene una apariencia benigna y suele ir acompañado de múltiples comorbilidades asociadas a la edad, lo que resulta en un aumento de las complicaciones e incluso la muerte. Con el incremento de la expectativa de vida a nivel mundial, el uso de medicamentos antitrombóticos es cada vez más frecuente. El papel de estos fármacos en la evolución de la enfermedad como en la recurrencia, sigue siendo motivo de discusión.
Métodos:
Los autores revisaron la fisiopatología y características clínicas del HSDC. El presente artículo discute acerca de las terapéuticas actuales y las nuevas opciones de tratamiento que podrían mejorar los resultados. Este manuscrito es susceptible de cambios en el tiempo, con el desarrollo científico y tecnológico.
Resultados:
El HSDC puede ser abordado por vía quirúrgica y farmacológica; no obstante, un manejo individualizado requiere la consideracion cuidadosa de diversos factores. A pesar de los avances en el campo de la neurocirugía, la clásica trepanación craneal sigue siendo el Gold estándar en el HSDC y sobre todo en pacientes con síntomas graves. Se debe resaltar que aún hay aspectos de este procedimiento (como la localización del dren, número de drenajes, el efecto de la irrigación, la temperatura de la solución con que se irriga, etc.) que siguen siendo materia de estudio.
Conclusiones:
Entender el mecanismo de la enfermedad ha permitido explicar su historia natural y a su vez proponer nuevas alternativas de tratamiento. El manejo médico (atorvastatina, corticoides) ha generado gran interés por sus alentadores resultados preliminares. Recientemente, se ha reportado la terapia endovascular como una alternativa segura y existe gran expectativa por confirmar su efecto en estudios más grandes.

Mortality and Outcome in Patients Older Than 80 Years of Age Undergoing Burr-Hole Drainage of Chronic Subdural Hematoma. World Neurosurg 2021; 150:e337-e346. [PMID: 33706018 DOI: 10.1016/j.wneu.2021.03.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2020] [Revised: 02/28/2021] [Accepted: 03/01/2021] [Indexed: 11/21/2022]
Abstract
OBJECTIVE Chronic subdural hematoma is frequently seen within the elderly population and neurosurgeons are confronted with patients older than 80 years presenting with symptomatic chronic subdural hematoma. However, data on surgical outcome are scarce. The aim of this study is to analyze the mortality and outcome after burr-hole drainage in patients older than 80 years. METHODS This is a single-center retrospective study including patients who underwent burr-hole drainage of chronic subdural hematoma between the years 2016 and 2019. The cohort was divided into 3 age groups (80-84 years; 85-89 years; >90 years). Primary outcome was 30-day and overall mortality, whereas secondary outcome measures were recurrence rates, postoperative bleeding rates, and outcome measured by the modified ranking scale. Uni- and multivariate analysis was conducted to assess for potential risk factors for mortality, recurrence and postoperative bleeding rates. RESULTS In total, 107 patients with a mean age of 85.5 ± 3.9 years were included. Mortality rate was less than 10% in each group, showing no significant difference between them (P = 0.455). No significant difference in recurrence and postoperative bleeding rates was seen (P = 0.491 and P = 0.532). Modified Ranking scale score differed significantly at release, whereas at follow-up no difference was seen. After uni- and multivariate analysis, age was not correlated with higher recurrence, postoperative bleeding, or mortality rates. Preoperative midline shift was found to be an independent risk factor for recurrence. CONCLUSIONS In patients older than 80 years undergoing burr-hole drainage for chronic subdural hematoma, age was not directly correlated with higher recurrence, postoperative bleeding, or mortality rates.

Functional recovery following surgery for chronic subdural hematoma. Surg Neurol Int 2020; 11:450. [PMID: 33408935 PMCID: PMC7771503 DOI: 10.25259/sni_689_2020] [Citation(s) in RCA: 3] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/01/2020] [Accepted: 11/21/2020] [Indexed: 01/08/2023] Open
Abstract
Background: Among the elderly, chronic subdural hematoma is a relatively common neurosurgical condition. Presenting symptoms range from headache and focal neurological deficits to seizure and coma depending on location and extent of brain compression. Functional recovery following surgery for chronic subdural hematoma is central to quality of life and ongoing health for elderly patients; however, there is a paucity of data regarding functional recovery in this population. Methods: In this study, the physical activity of patients who underwent surgical evacuation of chronic subdural hematoma was surveyed, as well as participation in physical therapy following surgery. In total, 38 patients completed the survey. Results: Of the 30 patients who exercised regularly before surgery, 28 (90.3%) returned to exercise within 1 year after surgery. Of 13 patients who reported playing hobby sports before surgery, 9 (69.2%) returned to those sports. 17/38 (44.7%) patients participated in physical therapy after surgery. 35/38 (92.1%) of patients reported that the surgery improved their quality of life. Conclusion: The majority of patients who underwent surgery for chronic subdural hematoma were able to return to exercise within 1 year. Participation in physical therapy was associated with return to exercise and sports. Further study is needed to determine which factors contribute to a return to baseline levels of physical activity following surgery for chronic subdural hematoma.

Surgical Treatment of Chronic Subdural Hematomas in Nonagenarians: Who to Treat? World Neurosurg 2020; 145:e274-e277.

Abstract
OBJECTIVE Although chronic subdural hematomas (cSDH) are often treated surgically it remains plausible that invasive treatment in elderly patients may have a negative effect on survival. The aim of this study was to characterize survival following neurosurgical intervention for cSDH in a selected cohort aged >90 years and to identify prognostic factors that may inform clinical decision-making. METHODS In total, we identified a cohort of 548 consecutive patients who had undergone burr hole drainage for cSDH in a 5-year period between 2009-2013. Of these patients, 41 were aged >90 years. For each patient, information was gathered from local hospital records, general practice records, and the patients directly. Long-term survival was compared with actuarial data obtained from the National Life Tables. RESULTS Overall mortality at the time of discharge was 2%. Mortality was 26.8% at 6 months, 36.8% at 1 year, and 47.9% at 2 years. Interestingly, there was no significant difference between the actuarial curve and the survival curve following surgery (hazard ratio, 1.17; confidence interval, 0.67-2.05; P = 0.57). Despite initially departing from the actuarial curve, the survival curve becomes parallel at approximately 1 year. Multivariate analysis showed that preadmission residence and the number of comorbid conditions were significant predictors of survival. CONCLUSIONS We advocate that neurosurgical intervention for cSDH in selected nonagenarians can be a safe and beneficial procedure. Patients living independently at home and with a limited past medical history were most likely to benefit from the surgery.

Risk-assessment in chronic subdural hematoma evaluated in 148 patients - A score for predicting recurrence. Clin Neurol Neurosurg 2020; 195:106020. [PMID: 32673990 DOI: 10.1016/j.clineuro.2020.106020] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2020] [Revised: 05/12/2020] [Accepted: 06/13/2020] [Indexed: 11/18/2022]
Abstract
BACKGROUND Chronic subdural hematoma (CSDH) is a frequent disease in neurosurgical practice. However, a considerable recurrence rate keeps this condition challenging to treat. We aimed to provide a simple tool for risk assessment in these patients. METHODS We conducted a retrospective analysis of surgically treated patients with chronic subdural hematomas. In addition to patients' demographics, radiological assessment included volume, thickness, midline shift and density of hematomas. Statistically significant variables in univariate analysis were further analyzed in a multivariate logistic regression model to create a risk score for recurrence of CSDH. RESULTS A total of 148 patients were identified and included for analysis. 50.7 % (n = 75) were older than 76 years of age. The overall hematoma recurrence rate requiring surgery was 23.6 % (n = 35). Preoperative thrombocytopenia, postoperative midline shift >6 mm, hematoma volume >80 mL and overall hematoma density >45 Hounsfield Units (HU), were significantly more frequent in the recurrence group. Furthermore, after multivariate assessment, postoperative hematoma density and volume were independent risk factors and included in the risk assessment tool. Patients were divided into 3 risk groups corresponding to the total scores. CONCLUSION We provide a risk-score assessment for predicting recurrence of subdural hematoma. The risk-score comprises postoperative hematoma volume and density. This tool could ease decision making in follow-up evaluation and indication for recurrence surgery. Yet, further prospective evaluation is required to assess the clinical value of this tool.

Abstract
OBJECTIVE The usefulness of endoscopic procedures for chronic subdural hematoma (CSDH) has been described, but the indications in patients of very advanced age have not been analyzed. The aim of this study was to evaluate the feasibility, safety, and usefulness of introduction of an endoscopic procedure for such patients. METHODS We retrospectively analyzed the data of 540 CSDHs treated by burr-hole surgery with endoscopic examination. The safety of the endoscopic procedure was assessed according to postoperative complications, morbidity, and mortality. The outcome was evaluated by statistical comparison among 4 different age-groups, and the recurrence rate and risk factors for recurrence was investigated in patients of very advanced age. RESULTS Postoperative complications occurred in 7 cases (1.5%). The 6-month morbidity and mortality were 13.5% and 4.5%. No complications, morbidity, or mortality associated with the additional endoscopic procedure occurred even in patients of very advanced age. The endoscopic features of trabecular structures and residual septa separating the cavity were also risk factors for recurrence in patients of very advanced age. Releasing of the septa showed the possibility of decreasing the risk of recurrence to 6.6% in patients aged ≥85 years as well as in younger patients. There were some inevitable problems such as prolongation of the surgical time and inadequate endoscopic surgical skill. CONCLUSIONS An endoscopic procedure for CSDH can be safely indicated and useful even in patients aged ≥85 years. However, clinicians should carefully select the patients based on clinical information associated with risk factors for recurrence.

Abstract
OBJECTIVE The purpose of this study was to describe the development of a novel prognostic score, the Subdural Hematoma in the Elderly (SHE) score. The SHE score is intended to predict 30-day mortality in elderly patients (those > 65 years of age) with an acute, chronic, or mixed-density subdural hematoma (SDH) after minor, or no, prior trauma. METHODS The authors used the Prognosis Research Strategy group methods to develop the clinical prediction model. The training data set included patients with acute, chronic, and mixed-density SDH. Based on multivariate analyses from a large data set, in addition to review of the extant literature, 3 components to the score were selected: age, admission Glasgow Coma Scale (GCS) score, and SDH volume. Patients are given 1 point if they are over 80 years old, 1 point for an admission GCS score of 5-12, 2 points for an admission GCS score of 3-4, and 1 point for SDH volume > 50 ml. The sum of points across all categories determines the SHE score. RESULTS The 30-day mortality rate steadily increased as the SHE score increased for all SDH acuities. For patients with an acute SDH, the 30-day mortality rate was 3.2% for SHE score of 0, and the rate increased to 13.1%, 32.7%, 95.7%, and 100% for SHE scores of 1, 2, 3, and 4, respectively. The model was most accurate for acute SDH (area under the curve [AUC] = 0.94), although it still performed well for chronic (AUC = 0.80) and mixed-density (AUC = 0.87) SDH. CONCLUSIONS The SHE score is a simple clinical grading scale that accurately stratifies patients' risk of mortality based on age, admission GCS score, and SDH volume. Use of the SHE score could improve counseling of patients and their families, allow for standardization of clinical treatment protocols, and facilitate clinical research studies in SDH.

Abstract
OBJECTIVE Chronic subdural hematoma (cSDH) is a prevalent condition often seen in the elderly, with surgery being the treatment of choice when symptomatic. So far, few have explored the surgical outcomes in patients 90 years or older. The aim of this study was to investigate outcome after cSDH surgery in nonagenarians (≥90 y/o group) compared to younger adult patients (<90 y/o group). MATERIALS In a Scandinavian population-based cohort we conducted a retrospective review of 1,254 patients undergoing primary burr-hole procedures for cSDH between January 1, 2005 and December 31, 2010 at three neurosurgical centers. In a comparative analysis, the primary end-point was difference in hematoma recurrence rates between the ≥90 y/o and <90 y/o groups. The secondary end-points were differences in perioperative morbidity and mortality between groups. RESULTS 75 patients were 90 years or older. There was no significant difference in recurrences resulting in reoperation between the age groups (10.7% vs 13.6%, P=.47). There was also no significant difference in overall complication rate (4.1% vs 8.1%, P=.21) or severe complications (1.4% vs 2.0%, P=.68). There were three (4.0%) perioperative deaths within 30 days in the ≥90 y/o group and 40 (3.4%) in the <90 y/o group (P=.78). CONCLUSION Patients 90 years or older had similar rates of recurrence, perioperative morbidity and perioperative mortality as compared to younger patients. Age alone should not be a contraindication for surgery in patients with cSDH.

Abstract
As the world population becomes progressively older, the overall incidence of chronic subdural hematoma (CSDH) is increasing. Peak age of onset for CSDH has also increased, and recently the 80-year-old level has a peak. Many patients with CSDH have had prior treatment with anticoagulants and antiplatelet drugs, which have an accompanying risk of CSDH. In elderly patients with CSDH, symptoms of cognitive change (memory disturbance, urinary incontinence, and decreased activity) and disturbance of consciousness at admission were more frequent compared to younger patients with CSDH. The literature actually offers conflicting advice regarding CSDH treatment; however, burr hole surgery with drainage under local anesthesia is the most common surgical procedure, even in elderly patients. The recurrence rate of CSDH has not decreased over recent decades, and it has ranged from 0.36-33.3%. Outcomes in patients over 75 years old was significantly worse than for those younger than 75. Moreover, long-term outcomes for elderly patients with CSDH are poor. CSDH in the elderly is no longer a benign disease. In the future, it will be important for us to understand the mechanisms of onset and recurrence of CSDH and to develop more effective medical treatments and noninvasive surgical techniques for elderly patients.

Abstract
Chronic subdural hematoma (cSDH) is a common condition, the frequency of which further increases due to an aging population and more frequent use of antithrombotic drugs. It leads to unspecific symptoms and neurological deficits and is usually treated surgically. Burr hole trepanation and twist drill craniostomy have become the therapeutic standards with craniotomy being rarely used for recurrent cases. Although recurrences are relatively common, in most cases a good outcome can be achieved even in the elderly; however, as cSDH is associated with other comorbidities, it is indicative of an increased morbidity and mortality. Controlled trials need to be carried out to determine whether pharmacological therapies can also be beneficial in addition to surgical treatment.

COXIBRAIN: results of the prospective, randomised, phase II/III study for the selective COX-2 inhibition in chronic subdural haematoma patients. Acta Neurochir (Wien) 2016; 158:2039-2044. [PMID: 27605230 DOI: 10.1007/s00701-016-2949-3] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/26/2016] [Accepted: 08/25/2016] [Indexed: 10/21/2022]
Abstract
BACKGROUND Chronic subdural haematomas (cSDHs) have shown an increasing incidence in an ageing population over the last 20 years, while unacceptable recurrence rates of up to 30 % persist. The recurrence rate of cSDH seems to be related to the excessive neoangiogenesis in the parietal membrane, which is mediated via vascular endothelial growth factor (VEGF). This is found to be elevated in the haematoma fluid and is dependent on eicosanoid/prostaglandin and thromboxane synthesis via cyclo-oxygenase-2 (COX-2). With this investigator-initiated trial (IIT) it was thought to diminish the recurrence rate of operated-on cSDHs by administering a selective COX-2 inhibitor (Celecoxib) over 4 weeks' time postoperatively in comparison to a control group. METHOD The thesis of risk reduction of cSDH recurrence in COX-2-inhibited patients was to be determined in a prospective, randomised, two-armed, open phase-II/III study with inclusion of 180 patients over a 2-year time period in four German university hospitals. The treated- and untreated-patient data were to be analysed by Fisher's exact test (significance level of alpha, 0.05 [two-sided]). RESULTS After screening of 246 patients from January 2009 to April 2010, the study had to be terminated prematurely as only 23 patients (9.3 %) could be enrolled because of on-going non-steroid anti-rheumatic (NSAR) drug treatment or contraindication to Celecoxib medication. In the study population, 13 patients were treated in the control group (six women, seven men; average age 66.8 years; one adverse event (AE)/serious adverse event (SAE) needing one re-operation because of progressive cSDH (7.7 %); ten patients were treated in the treatment group (one woman, nine men; average age 64.7 years; five AEs/SAEs needing two re-operations because of one progressive cSDH and one wound infection [20 %]). Significance levels are obsolete because of insufficient patient numbers. CONCLUSIONS The theoretical advantage of COX-2 inhibition in the recurrent cSDH could not be transferred into the treatment of German cSDH patients as 66.6 % of the patients showed strict contraindications for Celecoxib. Furthermore, 55 % of the patients were already treated with some kind of COX-2 inhibition and, nevertheless, developed cSDH. Thus, although conceptually appealing, an anti-angiogenic therapy with COX-2 inhibitors for cSDH could not be realised in this patient population due to the high prevalence of comorbidities excluding the administration of COX2 inhibitors.

Abstract
INTRODUCTION Chronic subdural haematoma (CSDH) is one of the most common neurosurgical conditions and is especially prevalent among elderly individuals. The objective of this study was to analyse the demographic, clinical and radiological findings, and surgical outcomes in a series of chronic subdural haematoma in patients older than 85 years. PATIENTS AND METHODS A review was carried out on all patients over 85 years with CSDH treated in our neurosurgical service from April 1986 to November 2015. A record was made of the baseline patient characteristics (age, sex, comorbidities, known risk factors, imaging characteristics, and number of burr-holes) and surgical outcomes (complications, especially recurrences and mortality). An analysis was carried out on the special characteristics of these patients, as well as the relationships between gender, clinical grade, anti-platelet or anticoagulant therapy, internal architecture of the haematoma, and midline shift, with mortality and recurrence of the haematoma. RESULTS A total of 200 patients were included, with a mean age of 88.5 (range 85-104) years, and the male: female sex ratio was 1:1.1. History of injury was reported in 114 (57%) cases. Anti-platelet or anticoagulant therapy was being used by 71 (35.5%) patients. On admission, 114 patients (57%) were in satisfactory condition (Markwalder grades 0-2). The main symptom was behavioural disturbance in 82 (41%) cases. CSDH was left-sided in 89 (44.5%) patients, right-sided in 78 (39%) cases (39%), and bilateral in the remaining 33 (16.5%) cases). Postoperative complications were observed in 59 cases (29 recurrences). Preoperative Markwalder grade correlated significantly with recurrence rate and mortality (P<.0001). CONCLUSIONS CSDH was a very common disease in very elderly patients. Behavioural disturbance and neurological deficits are the most common first symptom. Preoperative neurological status at admission is the most important factor in recurrences and mortality.

Abstract
Background Chronic subdural hematoma (CSDH) is a common disease that is more prevalent in older people. Surgical intervention is a safe treatment of choice. However, the recurrence rate is relatively high and the outcome is not always satisfactory among surgically treated patients. It is believed that aberrant angiogenesis and intracapsular inflammation contribute to the development of CSDH. Atorvastatin is reported to promote angiogenesis and suppress inflammation. We have recently shown that atorvastatin is effective to non-surgically reduce and eliminate CSDH with minimal side effects. Here, we report a clinical research trial protocol that is designed to evaluate the therapeutic effects of atorvastatin on CSDH. Methods/Design We have designed a multi-center, randomized, placebo-controlled, double blind clinical trial for evaluating the efficacy of oral atorvastatin in reducing CSDH. We have so far recruited 96 patients with CT-confirmed or MRI-confirmed CSDHs from 16 medical centers in China. These patients were originally recruited for the Oriental Neurosurgical Evidence-based Study Team (ONET) study. After informed consent is provided, patients are randomized to receive either atorvastatin (oral 20 mg/night for 8 weeks) or placebo (dextrin for 8 weeks); and followed for 16 weeks after the treatment. The primary outcome is the change in hematoma volume at the end of 8-week treatment. Secondary outcomes include: changes in 1) the hematoma volume at the 4th, 12th, and 24th weeks; 2) Markwalder’s Grading Scale and Glasgow Coma Scale (MGS-GCS); 3) Glasgow Outcome Score (GOS) and 4) Activities of Daily Life – the Barthel Index scale (ADL-BI). Safety will be assessed during the study by monitoring adverse events, laboratory tests, electrocardiography (ECG), measurements of vital signs (temperature, pulse, and blood pressure) and body weight. Discussion Results of this trial will provide critical information regarding whether atorvastatin is an effective and safe alternative to surgical treatment of CSDH.

Abstract
OBJECTIVE Chronic subdural hemorrhage (SDH) or hematoma is a condition that affects elderly individuals. With advances in medical care, the number of nonagenarians and centenarians will increase. However, surgical treatments in this age group are associated with high rates of morbidity and mortality. Because no data are available on the rates of survival among elderly patients with chronic SDHs who undergo surgical drainage or receive only conservative care, the goal of this study was to determine survival rates in patients 90 years of age or older with symptomatic chronic SDHs. METHODS The authors conducted a retrospective analysis of patient data that were collected at 3 hospitals over a 13-year period (from January 2001 to June 2013). The data from patients 90 years or older with symptomatic chronic SDHs and who were offered surgical treatment were included in the analysis. Patients who underwent surgical treatment were included in the surgical group and patients who declined an operation were included in the conservative care group. The patients' Charlson Comorbidity Index score, Karnofsky Performance Scale score, dates of death, presenting symptoms, Glasgow Coma Scale score, length of stay in the hospital, discharge location, side of the SDH, and neurological improvements at 30-day and 6-month follow-ups were recorded. Data were statistically analyzed with Fisher exact test, Kaplan-Meier curves, and logistic regression. RESULTS In total, 101 patients met the inclusion criteria of this study; 70 of these patients underwent surgical drainage, and 31 received conservative care. Patients in the surgical group had statistically significantly (p < 0.001) higher survival at both the 30-day and 6-month follow-ups, with 92.9% and 81.4% of the patients in this group surviving for at least 30 days and 6 months, respectively, versus 58.1% and 41.9%, respectively, in the conservative care group. Moreover, the mean overall length of survival of 34.4 ± 28.7 months was longer in the surgical group than it was in the conservative care group (11.3 ± 16.6 months). Overall, 95.7% of patients in the surgical group exhibited an improvement in neurological status after the SDH drainage, whereas none of the patients in the conservative care group showed any neurological improvement during their hospital stay. The surgical complication rate was 11.4%, and the overall rate of chronic SDH recurrence after surgery was 12.9%. CONCLUSIONS Surgical drainage of chronic SDHs in nonagenarians and centenarians is associated with lower incidence of inpatient death and higher 30-day and 6-month survival rates.

Abstract
Chronic subdural haematoma (CSDH) is one of the most common neurological disorders, and is especially prevalent among elderly individuals. Surgical evacuation is the mainstay of management for symptomatic patients or haematomas exerting significant mass effect. Although burr hole craniostomy is the most widely practised technique worldwide, approximately 10-20% of surgically treated patients experience postoperative recurrence necessitating reoperation. Given the increasing incidence of CSDH in a growing elderly population, a need exists for refined techniques that combine a minimally invasive approach with clinical efficacy and cost-effectiveness. In addition, nonsurgical treatment modalities, such as steroids, are attracting considerable interest, as they have the potential to reduce postoperative recurrence or even replace the need for surgery in selected patients. This Review provides an overview of the contemporary management of CSDH and presents considerations regarding future approaches that could further optimize patient care and outcomes.

Abstract
Background Chronic subdural hematoma (CSDH) is one of the most common diseases in neurosurgical practice, particularly among aged patients. With the continuing increase in the aged population, further increases in incidence are expected. However, few studies have focused on CSDH in super-aged patients over 90 years old. Methods We retrospectively reviewed medical records for 20 consecutive patients over 90 years old with CSDH treated in our department between 2007 and 2013. The diagnosis of CSDH was confirmed by computed tomography (CT). Patients were divided into a surgery group and a conservative group. Surgical procedures included burr-hole surgery followed by insertion of a subdural drain under local anesthesia. Clinical data were compared and analyzed. Neurological status was evaluated according to the modified Rankin Scale at three time points: before suffering from CSDH; at the time of referral or admission to our department; and at discharge or 1 month after the first referral. Statistical tests were used to analyze data and values of P < 0.05 were considered significant. Results Mean age for the 20 cases was 92.6 years (range, 90 - 96 years). The leading symptoms in this population were hemiparesis and gait disturbance, followed by disturbance of consciousness and speech disturbance. Twelve patients underwent burr-hole surgery. Mean maximum thickness of subdural hematoma as measured on CT was significantly higher in the surgery group (28.2 ± 5.4 mm) than in the conservative group (17.0 ± 3.8 mm; P < 0.01). Postoperatively, mean neurological status was significantly improved in the surgery group (P < 0.01). After surgery, 66.7% of patients could return home directly from hospital. No significant perioperative complications directly related to surgery were encountered in the surgery group, except for transient postoperative restlessness and bruising of extremities due to falls. Conclusions Surgery for CSDH is safe and positively recommended even in super-aged patients over 90 years old if the patient’s physical status is fair. Pre-illness status is the most important factor for considering operative indications and represents a limiting factor for postoperative outcomes in this age population.

Mini-craniotomy as the primary surgical intervention for the treatment of chronic subdural hematoma--a retrospective analysis. Acta Neurochir (Wien) 2014; 156:981-7.

Abstract
BACKGROUND The incidence of chronic subdural hematoma (CSDH) is increasing, but optimal treatment remains controversial. Recent meta-analyses suggest burr hole (BH) drainage is the best treatment because it provides optimal balance between recurrence and morbidity. Mini-craniotomy may offer supplementary technical advantages while maintaining equal or better outcomes. This study investigates the outcome of mini-craniotomy as the sole treatment in patients with CSDH. METHOD We analyzed all patients operated on for CSDH with mini-craniotomy in our neurosurgical center between 2005-2010. Baseline patient characteristics (age, sex, comorbidities, imaging characteristics, known risk factors for development of CSDH and neurological examination at presentation) and outcomes (mortality, complications, recurrence and neurological examination at discharge) were recorded. RESULTS One hundred twenty-six adult patients were included, mean age was 73.9 (range 18 to 95) years old, and the sex ratio (M:F) was 2:1. Eighty-four percent of the patients showed clinical improvement at discharge, as shown by a decrease in the Markwalder score postoperatively (with 57 % Markwalder 0 and 23 % Markwalder 1). Recurrence rate was 8.7 %. Overall complication rate was 34.1 % (27.8 % medical complications and 6.3 % surgical complications). In-hospital mortality was 13.5 % (8.7 % due to pulmonary infections and 1.6 % to surgical complications). Preoperative Markwalder grade correlated significantly with complication rate, as did the presence of a neurodegenerative disease (p = 0.018). Factors significantly related to mortality in univariate analysis were arterial hypertension (p = 0.038), heart failure (p = 0.02), renal failure (p = 0.017), neurodegenerative disease (p = 0.001), cerebrovascular accident (p = 0.008) and coagulopathy (p = 0.019). Multivariate analysis was not able to confirm any significant relationship. CONCLUSION This is the first published series of CSDH in which all consecutive patients were operated on by mini-craniotomy. The invasiveness and complication rate of mini-craniotomy are equal to those of burr hole treatment, but visualization is superior, resulting in lower recurrences. A randomized controlled trial is indicated to identify the best surgical strategy for the treatment of CSDH.

Abstract
Aim We evaluated the relation between general status on arrival and prognosis in patients aged 90 years and older who were admitted to our department through the emergency room, with the aim of assisting the development of a treatment policy for elderly people. Methods We retrospectively analyzed patients aged 90 years and older who were admitted to our department from January 2006 to September 2013. Patients were divided into two groups, patients who were discharged from our hospital or transferred to another hospital, and patients who died in our hospital. Comparisons of the patients' general status and the results of blood examinations were carried out between the two groups. Independent parameters to predict prognosis were also evaluated. Results Fifty-eight patients were enrolled in this study. The mean age was 93.2 ± 3.4 years (range, 90-106 years). Forty-five patients (77.6%) were discharged from our hospital (group A), and 13 patients (22.4%) died (group B). The percentage of patients with the inability to walk independently was significantly higher in group B. Mean arterial pressure, Glasgow Coma Scale (GCS), PaO2/FiO2 ratio, and serum albumin level on arrival were significantly better in group A. Multivariate logistic regression analysis indicated that the inability to walk independently (odds ratio, 22.4; 95% confidence interval, 4.4-113.1; P < 0.0001) and GCS (odds ratio, 7.0; 95% confidence interval, 1.8-27.7; P = 0.003) were the parameters to predict prognosis. Conclusion The inability to walk independently and GCS (consciousness status) are the most sensitive predictors of prognosis in emergency patients aged 90 years and older.
