ABSTRACT
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.
ABSTRACT
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.

OBJECTIVE: Chronic subdural hematoma drainage is one of the most common procedures performed in neurosurgical practice. Not only burr hole drainage but also small craniotomy (diameter 3–5 cm) is frequently used neurosurgical treatment of chronic subdural hematomas. We assessed to compare the postoperative recurrence rates between burr hole drainage versus small craniotomy with closed-system drainage for chronic subdural hematomas. METHODS: From January 2016 to December 2018, 75 patients who were treated with burr hole drainage and small craniotomy with closed system drainage for the symptomatic chronic subdural hematoma were enrolled. Pre and postoperative computed tomography (CT) were used for radiologic evaluation. The choice of procedure was decided by preoperative CT images. RESULTS: 60 patients out of 75 patients underwent burr hole drainage, whereas 15 patients underwent small craniotomy. The overall postoperative recurrence rate was 16%. The recurrence occurred in 8 patients out of 60 patients in burr hole drainage group (13.3%) and 7 patients out of 15 patients in small craniotomy group (46.7%). The number of days of hospitalization was 10.3 days in burr hole drainage group and 15.7 days in small craniotomy group. CONCLUSION: Burr hole drainage would be sufficient to evacuate chronic subdural hematoma with lower recurrence rate, but small craniotomy was also needed in some cases such as hematoma has solid portion or multiple septum.

OBJECTIVE: Burr hole craniostomy and closed-system drainage (BCD) is a common surgical procedure in the field of neurosurgery. However, complications following BCD have seldom been reported. The purpose of this study was to report our experiences regarding complications following BCD for subdural lesions. METHODS: A retrospective study of all consecutive patients who underwent BCD for presumed subdural lesions at one institute since the opening of the hospital was performed. RESULTS: Of the 395 patients who underwent BCD for presumed subdural lesions, 117 experienced surgical or nonsurgical complications. Acute intracranial hemorrhagic complications developed in 14 patients (3.5%). Among these, 1 patient died and 5 patients had major morbidities. Malposition of the drainage catheter in the brain parenchyma occurred in 4 patients, and opposite-side surgery occurred in 2 patients. Newly developed seizures after BCD occurred in 8 patients (2.0%), five of whom developed the seizures in relation to new brain lesions. Eighty-eight patients (22.3%) suffered from nonsurgical complications after BCD. Pulmonary problems (7.3%) were the most common nonsurgical complications, followed by urinary problems (5.8%), psychologic problems (4.3%), and cognitive impairments (3.8%). CONCLUSION: The incidence of complications after BCD for subdural lesions is higher than previously believed. In particular, catastrophic complications such as acute intracranial hematomas and surgical or management errors occur at rates that cannot be ignored, possibly causing medico-legal problems. Great caution must be taken during surgery and the postoperative period, and these complications should be listed on the informed consent form before surgery.

ABSTRACT Burr hole evacuation has been the most frequently-used procedure for the treatment of chronic subdural hematomas (CSDH). Objective: To evaluate whether the use of a drain and/or the number of burr holes for treatment of CSDH modifies the rates of recurrence and complications. Methods: A retrospective review of 142 patients operated on because of CSDH, between 2006 and 2015, analyzing recurrence and complications of the use of one or two burr holes with or without the use of a drain. Results: Thirty-seven patients had bilateral CSDH (26%) and 105 (73.9%) patients had unilateral CSDH. Twenty-two (59.4%) patients were given a drain and 15 (40.6%) were not. A total number of recurrences occurred in 22 (15.5%) patients and the total number of complications was in six (4.2%) patients. Mean follow-up time was 7.67 months. Conclusions: The number of burr holes and the use of the drain did not alter the rates of recurrence and complications in the treatment of CSDH.

ABSTRACT Trepanation has been performed by people interested in enhancing mental power and well-being since the early 1960s. The pioneers and main proponents of the procedure are described here. The phenomenon appeared in Europe after a Dutch former medical student published a psychoactive drug-friendly scroll suggesting trepanation as a form of permanently increasing cerebral blood volume and function. He trepanned himself in 1965. Three of his friends became enthusiasts. They also submitted themselves to the procedure and published films and books describing their experiences. Two of them coauthored papers, in collaboration with Russian researchers, and created institutions to promote discussion on trepanation. One of these institutions organized trips to Central and South America to get the operation done. Dozens of people nowadays look for trepanation as a method of spiritualization and increasing well-being and mental power. The phenomenon has an uncertain future, however, as the main proponents and supporters are aging.
RESUMO Trepanação vem sendo feita por pessoas em busca de aumento da capacidade mental e bem estar desde a década de 1960. Os pioneiros e maiores proponentes do procedimento são aqui descritos. O fenômeno surgiu na Europa estimulado pela publicação de um manuscrito psicodélico e pela auto-trepanação feita por um ex-aluno de Medicina holandês, já falecido. Três amigos se tornaram entusiastas e também se submeteram a trepanação, apresentando o procedimento e descrevendo seus efeitos em livros ou filmes de certa repercussão. Dois deles criaram organizações de difusão e discussão sobre o tema, e uma destas instituições agencia e organiza viagens a países da América Central e do Sul para interessados. Trepanação foi feita até aqui com estes propósitos em dúzias de pessoas. O fenômeno tem, porém, futuro incerto, dado o envelhecimento de seus principais entusiastas.

PURPOSE: This study investigated the surgical outcomes of canalicular trephination combined with endoscopic dacryocystorhinostomy (DCR) in patients with a distal or common canalicular obstruction. It also identified the factors affecting surgical success rates associated with this technique. METHODS: We retrospectively reviewed the medical records of 57 patients (59 eyes) in whom a canalicular obstruction was encountered during endoscopic DCR. All patients were treated with endoscopic DCR, followed by canalicular trephination and silicone tube placement. The surgical outcome was categorized as a functional success according to the patient's subjective assessment of symptoms, including epiphora, and as an anatomical success according to a postoperative nasolacrimal duct irrigation test. Surgical success rates were compared based on age, sex, location of the obstruction, number of silicone tubes, and experience of the surgeon. RESULTS: Functional success was achieved in 55 of 59 eyes (93%) at one month, 50 eyes (84%) at three months, and 46 eyes (78%) at six months. Anatomical success was achieved in 58 of 59 eyes (98%) at one month, 52 eyes (88%) at three months, and 50 eyes (84%) at six months. There was a statistically significant difference in surgical outcome according to the experience of the surgeon. The anatomical success rate at the six-month follow-up exam was 95.4% in the >5 years of experience group, and 53.3% in the <5 years of experience group (p = 0.008, Pearson chi-square test). CONCLUSIONS: The success rate of canalicular trephination combined with endoscopic DCR in patients with a distal or common canalicular obstruction decreased gradually during the six-month follow-up period. In particular, patients undergoing procedures with experienced surgeons tended to show excellent surgical outcomes at the six-month follow-up exam.

OBJECTIVE: Chronic subdural hematoma (CSDH), a disease commonly encountered by neurosurgeons, is treated by burr hole drainage (BHD). However, the optimal surgical technique among the three types of BHD has not been determined. METHODS: We conducted a retrospective study on BHD performed on 93 patients who were diagnosed with CSDH. The subjects were divided into three groups based on the surgical technique performed: single BHD without irrigation (Group A, n=31), double BHD without irrigation (Group B, n=32), and double BHD with irrigation (Group C, n=30). The clinical factors, radiological factors and recurrences were compared between the three groups. Moreover, independent factors affecting the recurrence were analyzed. RESULTS: The change in hematoma thickness was 29.77+/-7.94%, 49.73+/-12.87%, and 75.29+/-4.32% for Group A, B, and C, respectively, while the change in midline shift was 40.81+/-15.47%, 51.78+/-10.94%, and 56.16+/-16.16%, respectively. Thus, Group C showed the most effective for resolution of hematoma and midline shift (p<0.05). Group A, B, and C had 12 cases (38.7%), 8 cases (25.0%), and 3 cases (10.0%) of recurrences, respectively. Group C had a statistically significantly fewer recurrence rate than Group A (p<0.05). Double burr hole, irrigation, and coagulopathy were each identified as independent factors that reduce recurrence (p<0.05). CONCLUSION: Among the three techniques, the double BHD with saline irrigation resulted in the fewest recurrences. It is probably the most effective technique for preventing the recurrence of CSDH.

Objective To discuss a new effective method for treatment of chronic subdural hematoma in elderly patients. Methods Flush operation for elderly patients with chronic subdural hematoma(CSDH) by neuroendoscopy through burrhole approach were performed in 37 elderly patients. The mean age of the group was 68.5 years (60-86 years). 5 cases were recurrent after simple drainage. Thoroughly flushs the hematoma cavity under television monitor, removes the clot, coagulates the bleeding focus, break the septum of hematoma cavity to make it communicate with the normal subdural space. Results On following up 2-18 months, all the hematoma disappeared, 34 cases improved in clinic manifestation, no serious complications and death occurred. Conclusions Flush operation for elderly patients with chronic subdural hematoma by flexible neuroendoscopy through burrhole approach can improve the therapeutic effect and avoid the recurrence and the complilcations of the traditional drainage therapy.
ABSTRACT
Disminuir al máximo la mortalidad por hematoma subdural crónico (HSDC), es un reto que se debe alcanzar en todo centro neuroquirúrgico, en el que pueden influir el diagnóstico precoz y la adecuada selección del proceder quirúrgico. Se presentan 20 pacientes, 16 masculinos (80 %) y 4 femeninos (20 %), con una edad promedio para el grupo de 66,55 años, tratados quirúrgicamente por medio de la trepanación múltiple con lavado de la cavidad y drenaje cerrado al exterior. La angiografía carotídea constituyó el examen más utilizado para el diagnóstico 14 (70 %), seguida por la tomografía axial computadorizada (TAC) 8 (40 %). La escala de Bender se empleó para clasificar a los enfermos según el estado neurológico al ingreso, y se halló que el 80 % estaba en los grados I y II. Los resultados se evaluaron según la escala de resultados de Glasgow, y presentaron 17 (85 %), una buena recuperación.
To reduce as much as possible mortality from chronic subdural hematoma (CSDH) is a goal that should be attained by every neurosurgical center. An early diagnosis and an adequate selection of the surgical procedure may influence on it. 20 patients, 16 males (80 %) and 4 females (20 %) with an average age by group of 66.55 years of age were surgically treated by multiple trephining with lavage of the cavity and closed drainage. The carotid angiography was the most used test for the diagnosis with 14 (70 %), followed by computerized axial tomography (CAT) with 8 (40 %). Bender´s scale was utilized to classify the patients according to the neurological state at the time of admission . 80 % of them corresponded to degrees I and II. The results were evaluated by using the Glasgow´s scale. 17 (85 %) had a good recovery.
