title: [Chronic subdural hematomas treated by burr hole craniotomy with continuous drainage].
abstract: 60 cases of chronic subdural hematoma (CSDH) are reported in this paper. 59 cases were treated through burr holes, irrigation and drainage and 57 cases were completely cured after operation. The cure rate is 95%. In this group only three cases died due to neurological condition in grade III-IV (Stupor and Coma). The external membrane of hematoma is very rich in neocapillary and deposit with hemosiderin and exudate by fresh red blood cell. These findings support that the enlargement of a CSDH are not caused by hyperosmotic fluid within the hematoma but by continuous bleeding from the neocapillary of its outer membrane. The result of this surgical treatment is satisfactory, the operative procedure is safe and easy to perform, and there are no severe operative complications or accidents.
