Autor: Diasuke Ichinose, Yuzuru Hasegawa, Yohei Yamamoto, Jun Takei, Keisuke Hatano, Toshihide Tanaka, Satoru Tochigi, Fumiaki Maruyama, Yuichi Murayama

Publikováno v: Clinical neurology and neurosurgery. 202

The underlying mechanism of chronic subdural hematoma (CSDH) after minor head injury is complex, probably due to mechanical injury of the arachnoid membrane, hematological coagulopathy, and pathological angiogenesis in the dura caused by inflammatory
