The novel YL-1 hollow needle aspiration drainage system is an effective minimally invasive treatment in chronic subdural hematoma (CSDH). In order to find the risk prognosis factors of chronic subdural hematoma (CSDH) performed by the novel YL-1 hollow needle aspiration drainage system, a logistic analysis of postoperative results was performed. ⋯ We used logistic regression analysis to identify the risk prognosis factors of chronic subdural hematoma (CSDH) performed by a novel YL-1 hollow needle aspiration drainage systems, and found that high preoperative Markwalder's gradie, male, coagulopathy, bilateral hematoma, senior citizens will poorly affect prognosis in CSDH.
