Chronic subdural hematomas (CSDHs) are common in neurosurgical practice. There are no publications that report large series of the epidemiological characteristics of this pathology in Brazil. The purpose is to describe a large series of surgical cases and analyze the epidemiological and clinical characteristics.
We retrospectively analyzed patients with CSDH admitted into Neurosurgical Services at the Hospital de Base do Distrito Federal, Brasília, Brazil from 2006 to 2011. Age, sex, clinical feature, etiology, surgical procedure, side, clinical outcome, and recurrence were reviewed. Statistical tests were used to analyze data, and P < 0.05 was considered statistically significant.
The series included 778 patients. There were 643 (82.6%) male patients with a mean age of 64.3 ± 15.9 (range, 14-93) years. The principal symptom was headache (58.9%). The most frequent origin was a fall (282 cases, 36.2%), but the origin remained unclear in 281 (36.1%) patients. Mild head injury occurred in 540 (69.4%) cases. Burr holes with drainage were used as the surgical procedure in 96.5% patients, and 687 (88.3%) patients had a positive outcome. Mortality was 0%. Recurrence was observed in 42 cases.
The occurrence of CSDHs is more common in elderly men. Treatment with burr holes and drainage is a simple and safe method for treatment. In our experience, CSDH presents decreased morbidity and mortality.
慢性硬膜下血肿（CSDHs）在神经外科实践中很常见。在巴西，尚无出版物报道关于这种病理的大量流行病学特征。目的是描述一系列外科病例，并分析其流行病学和临床特征。
我们回顾性分析了2006年至2011年期间巴西巴西利亚联邦区基础医院神经外科收治的CSDH患者。对年龄、性别、临床特征、病因、手术方式、血肿部位、临床结局和复发情况进行了回顾。使用统计检验分析数据，P < 0.05被认为具有统计学意义。
该系列包括778例患者。男性患者643例（82.6%），平均年龄64.3±15.9岁（范围14 - 93岁）。主要症状为头痛（58.9%）。最常见的病因是跌倒（282例，36.2%），但281例（36.1%）患者的病因仍不明确。540例（69.4%）患者发生轻度头部损伤。96.5%的患者采用钻孔引流术，687例（88.3%）患者预后良好。死亡率为0%。42例患者出现复发。
CSDHs在老年男性中更常见。钻孔引流术是一种简单安全的治疗方法。根据我们的经验，CSDH的发病率和死亡率较低。
