摘要: OBJECTIVE Burr hole drainage has been widely used to treat chronic subdural hematoma (CSDH). However, the incidence of recurrent CSDH varies from 3.7 30% after surgery. The authors attempted elucidate risk factors associated with recurrence in one burr technique. METHODS A total 255 consecutive cases who underwent for were included this study. Twenty-four patients (9.4%) a repeated operation because CSDH. We analyzed retrospectively demographic, clinical and radiologic RESULTS In study, two found be independently high- mixed-density groups was significantly higher than those low- iso-density (p<0.001). Bleeding tendency such as leukemia, liver disease renal failure also (p=0.037). CONCLUSION These results suggest that mixed- density shown on computed tomographic scan closely relates high recurrence. Therefore, could delayed unless severe symptoms or signs are present. Reoperation using previous site is preferred modality
