RESUMEN
Introducción: El hematoma subdural crónico es la complicación tardía más frecuente del trauma craneoencefálico. Su diagnóstico precoz y el tratamiento oportuno permiten la evolución favorable y curación de los pacientes. Objetivo: Sistematizar los diferentes ejes de clasificación del hematoma subdural crónico, que permitan la evaluación multimodal con una orientación más precisa de la técnica quirúrgica. Métodos: Se realizó una revisión bibliográfica en las principales bases de datos disponibles, centrada en las diferentes clasificaciones clínicas y radiológicas del hematoma subdural crónico y se seleccionaron 26 artículos. Se escogieron las principales clasificaciones y escalas y se aplicaron en 22 pacientes, obteniéndose resultados preliminares. Resultados: Las escalas de evaluación clínica de Bender, Marckwalder y la clasificación de Gordon Firing son las más conocidas, sin embargo, existen clasificaciones tomográficas que tienen en cuenta la densidad, la homogeneidad del hematoma que son de gran importancia en la selección de la técnica quirúrgica. La presencia de membranas y tabiques aparecen solo incluidas dentro de la valoración de la densidad del hematoma. Existen otras con valor predictivo que identifican aquellos factores relacionados con las recurrencias, desde antes de la cirugía, las mismas se consideran un factor de mal pronóstico para la evolución final de los pacientes con este tipo de hematomas. Conclusiones: La evaluación preoperatoria exige de la aplicación de múltiples escalas, la identificación y caracterización de las membranas es importante para personalizar la técnica quirúrgica, en busca de disminuir la morbilidad y mortalidad posoperatoria.
Introduction: Chronic subdural hematoma is the most frequent late complication of cranioencephalic trauma. The early diagnosis and correct treatment allow the recovery of patients. Objective: To systematize the different criteria of classification of chronic subdural hematoma that leads the multimodal evaluation for more effective selection of surgical technique. Methods: A review of literature about chronic subdural hematoma was done in the main database focused on different clinical and radiological classifications and 26 articles were selected. The main classifications and scales were chosen and applied to 22 patients, obtaining preliminary results. Results : Benders, Marckwalder and Gordon Firing scales are the most common, nevertheless there are tomographic classifications that include density, homogeneity of hematoma that are of great importance in the selection of the surgical technique. The presence of membranes and septum are only included in the evaluation of hematoma density. There are some others with predictive value that identify those factors related to recurrences before surgery that are considered a bad prognosis to the final evolution of these patients with this type of hematoma. Conclusions: The previous evaluation to surgery requires the use of different scales, the identification and characterization of membranes are important to select the optimum surgical technique to decrease morbidity and mortality after surgery.
RESUMEN
Objective:To investigate the clinical efficacy of neuroendoscopic hematoma removal versus soft channel drainage in the treatment of chronic subdural hematoma. Methods:The clinical data of 102 patients with chronic subdural hematoma who received treatment in Jincheng People's Hospital from May 2018 to May 2020 were retrospectively analyzed. They were divided into the neuroendoscopy group ( n = 50) and the soft channel group ( n = 52) according to different surgical methods. Perioperative indexes, hematoma clearance rate, China Stroke Scale score, the activity of daily living score, and oxidative stress indexes were compared between the two groups. All patients were followed up for 3 months. The incidence of complications during the follow-up period was calculated. Results:The retention time of the drainage tube in the neuroendoscopy group was shorter than that in the soft channel group [(2.45 ± 0.63) days vs. (3.30 ± 0.78) days, t = 6.06, P < 0.001]. The length of hospital stay in the neuroendoscopy group was shorter than that in the soft channel group [(7.14 ± 1.65) days vs. (9.07 ± 2.11) days, t = 5.15, P < 0.001]. The hematoma clearance rate at postoperative 7 days in the neuroendoscopy group was higher than that in the soft channel group [(93.45 ± 5.50)% vs. (81.86 ± 7.24)%, χ2 = 9.12, P < 0.001]. There were no significant differences in operation time and intraoperative blood loss between the two groups (both P > 0.05). At postoperative 30 days, the China Stroke Scale score in the neuroendoscopy group was lower than that in the soft channel group [(12.74 ± 2.23) points vs. (18.67 ± 2.45) points, t = 12.79, P < 0.001]. The activity of daily life score in the neuroendoscopy group was significantly higher than that in the soft channel group [(77.69 ± 7.11) points vs. (91.35 ± 7.25) points, t = 9.60, P < 0.001]. At postoperative 7 days, glutathione peroxidase level in the neuroendoscopy group was significantly lower than that in the soft channel group [(130.75 ± 13.66) U/L vs. (148.60 ± 14.64) U/L, t = 6.37, P < 0.001]. Malondialdehyde level in the neuroendoscopy group was significantly lower than that in the soft channel group [(5.11 ± 0.65) nmol/L vs. (6.19 ± 0.74) nmol/L, t = 7.83, P < 0.001]. Superoxide dismutase level in the neuroendoscopy group was significantly higher than that in the soft channel group [(275.60 ± 22.33) U/L vs. (254.60 ± 18.55) U/L, t = 5.15, P < 0.001]. There was no significant difference in the incidence of complications between the two groups ( P > 0.05). Conclusion:Compared with soft channel drainage, neuroendoscopic hematoma removal can obtain better short-term curative effects and less oxidative stress response in the treatment of chronic subdural hematoma. Neuroendoscopic hematoma removal does not increase the incidence of postoperative complications and is highly safe.
RESUMEN
Objective:To investigate the clinical efficacy of neuroendoscopic hematoma removal versus soft channel drainage in the treatment of chronic subdural hematoma (CSDH) and their effects on neurological function and quality of life. Methods:The clinical data of 97 patients with CSDH who received treatment between February 2018 and December 2019 were retrospectively analyzed. These patients were divided into group A ( n = 48, soft channel drainage) and group B ( n = 49, neuroendoscopic hematoma removal) according to different surgical methods. Clinical indicators, neurological function, quality of life, and incidence of complications were compared between groups A and B. Results:Operative time, length of hospital stay, and latency to hematoma disappearance in group B were (31.3 ± 2.18) minutes, (8.16 ± 1.32) days, (7.45 ± 1.49) days, which were significantly shorter than those in group A [(35.15 ± 4.32) minutes, (13.18 ± 1.56) days, (11.32 ± 1.88) days, t = 5.53, 17.12, 11.25, all P < 0.001]. At 3 months after surgery, the score of each dimension of SF-36 in each group was increased. The scores of physiological functioning, bodily pain, mental health, general health perceptions, social role functioning, vitality, role limitations due to emotional health, role limitations due to physical health in group B were (84.94 ± 7.25) points, (84.02 ± 6.29) points, (82.85 ± 8.16) points, (84.36 ± 9.15) points, (83.51 ± 10.39) points, (82.68 ± 8.36) points, (84.93 ± 10.15) points, (86.12 ± 9.13) points, which were significantly higher than those in group A [(62.68 ± 5.47) points, (71.39 ± 7.42) points, (69.51 ± 6.39) points, (72.68 ± 7.36) points, (72.81 ± 8.15) points, (73.12 ± 10.13) points, (77.91 ± 9.52) points, (75.32 ± 7.51) points, t = 19.82, 18.34, 19.75, 16.71, 17.94, 20.57, 18.22, 16.44, all P < 0.001]. At 7 days after surgery, neurotrophic factor, neuron specific enolase, hydrogen sulfide and S100B protein levels in group B were (42.53 ± 6.09) μg/L, (6.52 ± 2.79) μg/L, (203.17 ± 15.03) μmol/L, (0.25 ± 0.05) μg/L, respectively, which were significantly lower than those in group A [(67.38 ± 7.42) μg/L, (9.18 ± 2.27) μg/L, (242.79 ± 14.08) μmol/L, (0.36 ± 0.07) μg/L, t = 17.94, 5.12, 13.33, 8.86, all P < 0.001]. There was no significant difference in the incidence of complications between group B and group A [8.16% (4/49) vs. 18.75% (9/48), χ2 = 2.22, P = 0.136]. Conclusion:Compared with soft channel drainage, neuroendoscopic hematoma removal can better improve clinical indicators, neurological function, and quality of life in patients with CSDH, and is highly safe Neuroendoscopic hematoma removal is of certain clinical application value and innovation.
RESUMEN
Introducción: El hematoma subdural crónico es un hematoma encapsulado por dos membranas interna y externa. Existen diferentes clasificaciones imagenológicas que incluyen las características de estas lesiones, pero la presencia de las membranas y sus características es un aspecto poco descrito. Objetivo: Describir las características tomográficas de las membranas de los hematomas subdurales crónicos. Métodos: Se realizó un estudio descriptivo en el Servicio de Neurocirugía en conjunto con el Servicio de Imagenología, del Hospital Universitario Manuel Ascunce Domenech durante el año 2021. Se incluyeron 20 pacientes adultos que fueron operados con el diagnóstico de hematoma subdural crónico. Las membranas se caracterizaron de acuerdo con su densidad, grosor, número de capas, morfología y extensión. Resultados: Predominaron los pacientes de más de 65 años del sexo masculino, con hematomas unilaterales más frecuentes del lado izquierdo. El volumen promedio fue de 150 ml y el diámetro fue de 3 cm. Fueron más frecuentes las membranas finas, hiperdensas, incompletas, de una sola capa y la morfología fue variable. Conclusiones: Las membranas que conforman el hematoma subdural crónico pueden observarse en la tomografía axial computarizada. Se han encontrado diferentes tipos de membranas de acuerdo con su densidad, grosor, morfología, extensión y presencia de tabiques. La presencia de una membrana gruesa o fina con tabiques, puede tener indicación de una craneotomía que permita la resección cuidadosa de la membrana parietal y la apertura suficiente de la visceral para facilitar la re expansión cerebral y disminuir la incidencia de recolecciones.
Introduction: Chronic subdural hematoma is a hematoma encapsulated by two internal and external membranes. There are different imaging classifications that include the characteristics of these lesions, but the presence of the membranes and their characteristics is a little described aspect. Objective: To describe the tomographic characteristics of the membranes of chronic subdural hematomas. Methods: A descriptive study was carried out in the Neurosurgery service in conjunction with the Imaging service of the Manuel Ascunce Domenech University Hospital during the year 2021. 20 adult patients who underwent surgery with the diagnosis of chronic subdural hematoma were included. The membranes were characterized according to their density, thickness, number of layers, morphology and extension. Results: Male patients over 65 years of age predominated, with more frequent unilateral hematomas on the left side. The average volume was 150 ml and the diameter was 3 cm. Thin, hyperdense, incomplete, single-layer membranes were more frequent, and the morphology was variable. Conclusions: The membranes that make up the chronic subdural hematoma can be seen on computerized axial tomography. Different types of membranes have been found according to their density, thickness, morphology, extension and presence of septa. The presence of a thick or thin membrane with septa may indicate a craniotomy that allows careful resection of the parietal membrane and sufficient opening of the visceral membrane to facilitate brain re-expansion and reduce the incidence of recollections.
RESUMEN
Objective:To identify the effects of Xuefu Zhuyu Capsule (XZC) on the surgical treatment of patients with chronic subdural hematoma (CSDH).Methods:Retrospectively collected 96 pairs of patients who undergoing burr-hole craniotomy (BHC) for CSDH from January 2016 to December 2019 in Dalian Municipal Central Hospital. Clinical characteristics and imaging information of each patient were extracted, the follow-up period was six months. Differences in demographics and postoperative outcomes were compared between BHC+XZC group and BHC only group. Univariate analysis and multivariate analysis with Logistic regression model were performed to determine independent associations among the various probable effective factor. The relationship between related factors and effectiveness of CSDH was estimated with odds ratio ( OR) and 95% CI. Results:Effectiveness in 87 cases (90.6%) patients with surgery and received XZC postoperatively was significantly higher than 76 cases (79.2%) patients who underwent surgery alone. Multivariate Logistic regression analysis showed postoperative administration of XZC and preoperative Glasgow coma scale (GCS) score were independent protective factors for CSDH to improve therapeutic effect.Conclusions:This study suggested postoperative administration of XZC for CSDH patients can improve the therapeutic effect, a higher preoperative GCS score is contributed to the postoperative effect.
RESUMEN
RESUMEN Durante la pandemia COVID-19 se ha incrementado el uso de la telemedicina y de plataformas virtuales en el campo de la medicina, por ello, en nuestra institución contamos con un sistema multicámara que permite la visualización en vivo de procedimientos endovasculares. Se realizaron once casos de aneurismas, malformaciones arteriovenosas y hematomas subdurales crónicos que fueron tratados y transmitidos en vivo sin problemas técnicos a través de la plataforma Zoom®. El tiempo promedio de transmisión y del número de participantes fue de 2.5 horas y 6 participantes, respectivamente. En todos los casos se discutió la técnica empleada y las complicaciones ocurridas. El aprendizaje remoto con plataformas en línea es hoy en día una herramienta importante, pero no un sustituto del aprendizaje práctico para procedimientos endovasculares. Recomendamos su implementación durante la pandemia de COVID-19 como un sustituto temporal, especialmente para los médicos en entrenamiento que no tienen acceso a intervenciones endovasculares avanzadas.
ABSTRACT During the COVID-19 pandemics there has been a substantial increase in the use of telemedicine and virtual platforms in the medical field. For this reason, we have in our institution a multi- camera system that allows us live visualizing endovascular procedures. Eleven cases dealing with aneurysms, arteriovenous malformations and chronic subdural hematomas were treated and broadcasted live with no technical problems using the Zoomâ platform. The average time for transmissions was 2.5 hours, and the average number of participants was 6 persons. The used technique and occurring complications were discussed for all cases. Remote learning using online platforms is nowadays a very important tool, but it is not a substitute for practical learning when performing endovascular procedures. We recommend to implement such techniques during COVID-19 pandemics as a temporary substitute for live learning, particularly for young in-training physicians who may not have access to advanced endovascular interventions.
RESUMEN
RESUMEN El hematoma subdural crónico (HSDC) es una patología neuroquirúrgica frecuente, con una recurrencia de hasta el 30% de los casos. La embolización de la arteria meníngea media (AMM) es una estrategia de manejo adyuvante para disminuir la recidiva, especialmente en pacientes con factores de riesgo para recurrencia, y tiene una baja tasa de complicaciones. Presentamos el caso de un varón de 83 años con antecedente de anticoagulación, que es admitido en centro sanitario por presentar hemiparesia derecha, disartria y alteración de la marcha, con un tiempo de enfermedad de una semana. Se realizó trepanación y evacuación del HSDC sin complicaciones. Un mes después retornó por recidiva del HSDC, por lo que se realizó trepanación y evacuación adecuada del HSDC, seguida de embolización de la AMM ipsilateral. El control a los dos meses mostró ausencia de recidiva, con mejoría neurológica del paciente. Concluimos que la embolización de la AMM fue un tratamiento adyuvante eficaz para disminuir la recidiva del HSDC y podría estar indicada en pacientes con factores de riesgo asociados a la recurrencia.
ABSTRACT Chronic subdural hematoma (CSDH) is a frequent neurosurgical condition, which may develop recurrence in up to 30% of all cases. Embolization of the middle meningeal artery (MMA) is an adjuvant management strategy for reducing recurrence, especially in patients with risk factors, and it has a low complication rate. We present the case of an 83-year old male with history of anticoagulation, who was admitted in a healthcare facility because of right hemiparesis, dysarthria and gait impairment, and he had been sick for one week. A trepanation and CSDH evacuation were uneventfully performed. One month later, the patient was brought back because of CSDH recurrence, so another trepanation and adequate CSDH evacuation were performed, followed by embolization of the ipsilateral MMA. A control assessment after two months revealed absence of recurrence and neurological improvement. We conclude that MMA embolization was an efficacious adjuvant therapy aiming to reduce CSDH recurrence, and this procedure may be indicated in patients with risk factors for recurrence.
RESUMEN
SUMMARY OBJECTIVES: To identify recurrence and its potential predisposing factors in a series of 595 patients with an initial diagnosis of Chronic Subdural Hematoma (CSDH) who underwent surgical treatment at a Reference Hospital of São Paulo. METHODS: A retrospective descriptive study, in which the medical records of all patients with a CSDH diagnosis submitted to surgical treatment from 2000 to 2014 were analyzed. RESULTS: The final study population consisted of 500 patients with a diagnosis of CSDH (95 patients with a diagnosis of Cystic Hygroma were excluded), of which 27 patients presented recurrence of the disease (5.4%). There were no statistically significant differences in relapses when cases were stratified by gender, laterality of the first episode or surgical procedure performed in the first episode (trepanning vs. craniotomy). It was possible to demonstrate an age-related protective factor, analyzed as a continuous variable, regarding the recurrence of the CSDH, with a lower rate of recurrence the higher the age. CONCLUSIONS: The results indicate that, among possible factors associated with recurrence, only age presented a protective factor with statistical significance. The fact that no significant difference between the patients submitted to trepanning or craniotomy was found favors the preferential use of burr-hole surgery as a procedure of choice due to its fast and less complex execution.
RESUMO OBJETIVOS: Identificar a taxa de recidiva e seus potenciais fatores predisponentes em série de 595 pacientes consecutivos com diagnóstico inicial de hematoma subdural crônico (HSDCr) submetidos a tratamento cirúrgico em hospital terciário de São Paulo nos últimos 14 anos. MÉTODOS: Estudo retrospectivo descritivo, no qual foram analisados os prontuários de todos os pacientes com diagnóstico de HSDCr submetidos a tratamento cirúrgico, no período de 2000 a 2014. RESULTADOS: A amostra final consistiu em 500 pacientes com diagnóstico de HSDCr — foram excluídos 95 pacientes com diagnóstico de higroma cístico —, dos quais 27 sujeitos apresentaram recidiva do quadro (5,4%). Não foram observadas diferenças estatisticamente significativas nas recidivas quando os casos foram estratificados por gênero, lateralidade do primeiro episódio ou procedimento cirúrgico executado no primeiro episódio (trepanação vs. craniotomia). Foi possível demonstrar um fator protetor relacionado à idade, analisado como variável contínua, no que diz respeito à recidiva do HSDCr, com menor taxa de recidiva com o avançar desta CONCLUSÕES: Os resultados indicam que, dentre os fatores possivelmente associados à recidiva, apenas a idade se apresentou como fator protetor com significância estatística. O fato de não ser demonstrada diferença significativa entre os pacientes submetidos a tratamentos cirúrgicos por trepanação ou por craniotomia favorece o uso preferencial da trepanação como procedimento de escolha, em virtude de apresentar execução rápida e menos complexa.

Most patients with chronic subdural hematoma (CSDH) have a history of craniocerebral trauma.Avulsion of intracranial pontine vein is the main pathogenesis after craniocerebral injury.CSDH drilling and drainage is the most widely used surgical method,with low recurrence and mortality rate.However,the postoperative complication of subdural pyometra is extremely rare,which leads to high mortality and disability rate and thus representing a very challenging disease in trauma surgery.Old age,diabetes mellitus,drainage with foreign body,craniocerebral surgery,open wound,chronic systemic infectious diseases (sinusitis,otitis media,abdominal abscess,lung infection,urinary tract infection),tumor or immune deficiency diseases are all the high risk factors.This paper reviews the pathogenesis,pathogenic bacteria,clinical manifestations,auxiliary examination,treatment and prognosis of subdural empyema after CSDH drilling and drainage in recent years,and provides suggestions for clinical management.
RESUMEN
Objective To investigate the clinical characteristics and surgical results of patients with chronic subdural hematoma (CSDH) in different age groups.Methods 150 CSDH patients admitted to our hospital from January 2014 to January 2019 were selected as the research objects,and their clinical data were reviewed and collected.According to different age,they were divided into three groups:the ＜ 55 year old group (n =46),the 55-70 year old group (n =62),and the ＞ 70 year old group (n =42).The imaging examination results and clinical manifestations of three groups of patients in different age groups were compared.Combined with patients'wishes and surgical indications,150 patients were treated with traditional burr hole and drainage and modified operation.The results of different operation methods in three groups were compared.Results The incidence of headache/dizziness in the 55-70 year old group was higher than that in ＞ 70 year old group (P ＜ 0.05).The incidence of language disorder in the 55-70 year old group and ＞ 70 year old group was higher than that in ＜ 55 year old group,with statistically significant difference (P ＜0.05).The incidence of limb paralysis in the 55-70 year old group and the ＞70 year old group was higher than that in ＜ 55 years old group,with statistically significant difference (P ＜ 0.05).The incidence of mental disorders in the ＞ 70 year old group was higher than that in 55-70 year old group and ＜ 55 year old group,with statistically significant difference (P ＜ 0.05).The incidence of fecal incontinence in the ＞ 70 year old group was higher than that in 55-70 year old group and ＜ 55 years old group,with statistically significant difference (P ＜ 0.05).The imaging examination results of the three groups showed significant differences (P ＜ 0.05).According to the estimation of the amount of hematoma by the Dutian (DOTA) formula,the amount of hematoma in the group of ＞70 years old was significantly higher than that in the group of ＜ 55 years old and 55-70 years old,with statistically significant difference (P ＜0.05).Among the three groups,the proportion of patients with good prognosis after modified operation was higher than that of traditional operation,and the recurrence rate was lower than that of traditional operation,with statistically significant difference (P ＜ 0.05).The proportion of good prognosis and recurrence rate in group ＞ 70 years old were lower than those in the group of ＜ 55 years old and 55-70 years old (P ＜0.05).Conclusions CSDH patients of different ages have different characteristics in imaging examination results and clinical manifestations.Traditional burr hole drainage and modified operation can achieve certain results,but modified operation is more effective and can reduce the incidence of postoperative complications,which is worth popularizing.
RESUMEN
Objective To investigate the effects of single-hole and double-hole drilling and closed drainage on the expression of Hypoxia inducible factor-1α (HIF-1α),Claudin-5,transforming growth factor-β (TGF-β) and Smad2/3 in the epidermis of patients with chronic subdural hematoma.Methods 100 patients with chronic subdural hematoma were randomly divided into single hole and double hole drainage group according to random number table.Immunohistochemical streptavidin-peroxidase (SP) was used to detect the expression of TGF-β protein,and Western blot was used to detect the expression of HIF-1α,Claudin-5 and Smad2/3 in the epihematoma of the two groups before and after operation.Results Compared with pre-operation,the expression of HIF-1 α,TGF-β and Smad2/3 protein in adventitia of hematoma in both groups decreased after operation,especially in the double-hole group (P ＜ 0.05).The expression of Claudin-5 protein in adventitia of hematoma was significantly increased in both groups,especially in the double-hole group,with statistically significant difference (P ＜ 0.05).Conclusions Single-hole and double-hole drilling and sealing drainage is an effective method to treat chronic subdural hematoma.It can reduce the expression of HIF-1α,TGF-β and Smad2/3 protein in the epidermis of hematoma,and significantly increase the expression of Claudin-5,and the effect of double-hole drilling and sealing drainage is more significant.
RESUMEN
Treatment of chronic subdural hematoma (CSDH) is relatively straightforward, however, there is still some debate regarding the best strategy for treatment. The most practical recommendations of up to date were identified by a review of literature. The author reviewed the literature on CSDH management from the past to now to identify the best methods. Till 1970s, craniotomy was the most commonly used method. Burr hole (BH) became the most preferred method from 1980s. In 1977, twist drill (TD) craniostomy was introduced. Closed system drainage after a BH or a TD became the most frequently used surgical method. Although nonsurgical treatment is often successful, trephination has more advantages, such as rapid resolution of the symptoms and short period of hospitalization. Nonsurgical treatment is possible in asymptomatic patients with a small CSDH. For the symptomatic patients with CSDH, trephination is the treatment of choice, either by BH or TD. In gray zone between surgery and medical treatment, shared decision making can be an ideal approach. For the recurrent CSDHs, repeated trephination is still effective for patients with a low risk of recurrence. If the risk of recurrence is high, additional management would be helpful. For the refractory CSDHs, it is necessary to obliterate the subdural space.

Most patients with chronic subdural hematoma (CSDH) have a history of craniocerebral trauma. Avulsion of intracranial pontine vein is the main pathogenesis after craniocerebral injury. CSDH drilling and drainage is the most widely used surgical method, with low recurrence and mortality rate. However, the postoperative complication of subdural pyometra is extremely rare, which leads to high mortality and disability rate and thus representing a very challenging disease in trauma surgery. Old age, diabetes mellitus, drainage with foreign body, craniocerebral surgery, open wound, chronic systemic infectious diseases (sinusitis, otitis media, abdominal abscess, lung infection, urinary tract infection), tumor or immune deficiency diseases are all the high risk factors. This paper reviews the pathogenesis, pathogenic bacteria, clinical manifestations, auxiliary examination, treatment and prognosis of subdural empyema after CSDH drilling and drainage in recent years, and provides suggestions for clinical management.

Although nonsurgical treatment is often successful, trephination has more advantages, such as rapid resolution of the symptoms and short period of hospitalization. Nonsurgical treatment is possible in asymptomatic patients with a small CSDH. For the symptomatic patients with CSDH, trephination is the treatment of choice, either by BH or TD. In gray zone between surgery and medical treatment, shared decision making can be an ideal approach. For the recurrent CSDHs, repeated trephination is still effective for patients with a low risk of recurrence. If the risk of recurrence is high, additional management would be helpful. For the refractory CSDHs, it is necessary to obliterate the subdural space.

OBJECTIVE: Diffusion-weighted magnetic resonance imaging (DW-MRI) has proven useful in the study of the natural history of ischemic stroke. However, the potential of DW-MRI for the evaluation of chronic subdural hematoma (CSDH) has not been established. In this study, we investigated DW-MRI findings of CSDH and evaluated the impact of the image findings on postoperative outcomes of CSDH. METHODS: We studied 131 CSDH patients who had undergone single burr hole drainage surgery. The images of the subdural hematomas on preoperative DW-MRI and computed tomography (CT) were divided into three groups based on their signal intensity and density: 1) homogeneous (iso or low) density on CT and homogeneous low signal intensity on DW-MRI; 2) homogeneous (iso or low) density on CT and mixed signal intensity on DW-MRI; and 3) heterogeneous density on CT and mixed signal intensity on DW-MRI. On the basis of postoperative CT, we also divided the patients into 3 groups of surgical outcomes according to residual hematoma and mass effect. RESULTS: Analysis showed statistically significant differences in surgical (A to B: p < 0.001, A to C: p < 0.001, B to C: p=0.129) and functional (A to B: p=0.039, A to C: p < 0.001, B to C: p=0.108) outcomes and treatment failure rates (A to B: p=0.037, A to C: p=0.03, B to C: p=1) between the study groups. In particular, group B and group C showed worse outcomes and higher treatment failure rates than group A. CONCLUSION: CSDH with homogeneous density on CT was characterized by signal intensity on DW-MRI. In CSDH patients, performing DW-MRI as well as CT helps to predict postoperative treatment failure or complications.

Objective To evaluate the clinical effect of chronic subdual hematoma between surgical procedure twist drill craniostomy with injecting urokinase into hematoma space and only with twist drill craniostomy.Methods Two hundred and twenty-five patients with chronic subdual hematoma patients who were admitted in the Affiliated Hospital of Yangzhou University from January 2011 to April 2017 were retrospectively analyzed.They were divided into two groups according to the different surgical methods,group A for twist drill craniostomy with injecting urokinase into hematoma space (n =116),group B only for twist drill craniostomy (n =109).Then the postoperative drainage volume and residual hematoma was analyzed by repeated measures,while radiographic grading system and recurrence rates after operation were compared between groups with statistical analysis which was done by ANOVA analysis or non-parametric rank sum test.Results The drainage volume 48 hours after surgery was(52.41 ± 7.86) ml in group A,(28.42 ± 4.46) ml in group B as well.The residual volumes which were calculated at 1 month,3 months after surgery was (23.35 ±4.18) ml and (15.31 ±6.15) ml in group A,comparing the volumes of (46.07 ± 5.96) ml and (25.60 ± 5.03) ml in group B.The radiographic grading system was evaluated by grade 1-4.There were 75(64.7％) cases in grade 1,32(27.6％) cases in grade 2,8(6.9％) cases in grade 3,1 (0.9％) cases in grade 4 of group A,as well as 42(38.5％) cases in grade 1,55(50.5％) cases in grade 2,11 (10.1％) cases in grade 3,1 (0.9％) cases in grade 4 of group B.The rate of recurrence for chronic subdural hematoma was 6.0％ in group A,while it was 15.6％ in group B.These data all had significant statistical difference between the two groups (P ＜ 0.05).Conclusion Twist drill craniostomy might be a safe,effective and mini-massive method for treating chronic subdual hematoma,while injecting urokinase into the hematoma space could significantly reduce the rate of recurrence and decrease the volume of hematoma.
RESUMEN
Objective To analyze the incidence and predictors of chronic subdural hematoma (CSDH) after surgical clipping between unruptured intracranial aneurysms (UIAs) and ruptured intracranial aneurysms (RIAs).Methods A retrospective cohort study was adopted to collect 486 cases of aneurysm patients (102 cases of UIAs patients and 384 RIAs patients) closed by aneurysm surgery who were admitted to the department of neurosurgery of The Fifth People's Hospital of Chengdu from October 2009 to December 2017.The clinical data,preoperative and postoperative imaging data and postoperative follow-up results were collected.The incidence of CSDH after operation in UIAs patients and RIAs patients was compared.The risk factors of CSDH after UIAs and RIAs patients were analyzed by multivariate Logistic regression model.Results The incidence of CSDH in UIAs and RIAs patients (10.78％ vs 3.13％,x2 =10.487,P =0.001) and the reoperation rate after CSDH (3.92％ vs 0.78％;x2 =5.599,P =0.018) were all statistically different,all of which showed that the patients with UIAs were higher than those of the patients with RIAs.Brain atrophy of grade 3-4 (OR =1.978,95％ CI:1.939-2.030,P ＜ 0.001),subdural effusion CT value ≥40 (OR =3.394,95％ CI:2.908-3.867,P ＜ 0.001) and subdural effusion (OR =2.872,95％ CI:2.648-3.019,P ＜0.001 grade) of Ⅰ B are independent risk factors of CSDH in patients with UIAs after aneurysm clipping (P ＜0.05).Subdural effusion CT value ≥ 40 (OR =3.442,95％ CI:2.918-3.8769,P ＜ 0.001) and grade Ⅰ B subdural effusion (OR =2.329,95％ CI:2.011-2.564,P ＜ 0.001) are independent risk factors for CSDH in patients with RIAs after aneurysm clipping (P ＜0.05).Conclusions The incidence of CSDH after aneurysm clipping in UIAs patients was significantly higher than that of RIAs patients.The risk factors for CSDH in the two groups were not the same.
