Recurrence of chronic subdural hematoma after surgery has not been eliminated. We sought to determine whether irrigation influences recurrence rate.
Patients who had undergone surgery for chronic subdural hematoma were reviewed retrospectively.
Between 1986 and 1993, 186 cases of chronic subdural hematoma were treated surgically at Mito National Hospital. Recurrence was limited to six cases (3.2%). A closed drainage system without irrigation has been used since 1988 in 119 patients. Before 1988, 67 cases were treated with single burr hole irrigation and drainage. The rate of recurrence with the closed drainage system was 3.4% (four cases), compared with 3.0% (two cases) for irrigation and drainage.
Compared with irrigation and drainage, the closed drainage system without irrigation was safe and effective, and recurrence of chronic subdural hematoma is not influenced by irrigation.
慢性硬膜下血肿术后复发问题尚未消除。我们试图确定冲洗是否会影响复发率。
对接受过慢性硬膜下血肿手术的患者进行回顾性研究。
1986年至1993年期间，水户国立医院对186例慢性硬膜下血肿患者进行了手术治疗。复发仅6例（3.2%）。自1988年起，119例患者采用了不冲洗的闭式引流系统。1988年以前，67例患者采用单钻孔冲洗引流治疗。闭式引流系统的复发率为3.4%（4例），而冲洗引流的复发率为3.0%（2例）。
与冲洗引流相比，不冲洗的闭式引流系统安全有效，慢性硬膜下血肿的复发不受冲洗影响。
