Most chronic Subdural hematomas (CSH) are caused by trauma, but they sometimes occur nontraumatically or after surgery for nontraumatic intracranial disease. During the past 5 years, the author encountered 10 cases of postoperative CSH. They included five of 101 patients who had undergone extra-intracranial anastomosis (5.0%), four of 177 who had received ventriculoperitoneal shunts (2.3%), and one of 233 who had undergone aneurysmal repair (0.4%). Computerized tomographic, operative, and pathological findings were the same as in traumatic CSH. Four cases were resolved by surgery and two by blocking of the shunt system; four patients recovered without therapy. CSH appears to develop under specific conditions, namely, cerebrospinal fluid or a mixture of blood and cerebrospinal fluid remain in the subdural space for a long interval. Cerebral compliance may play an important role in the aggravation of nontraumatic CSH.
