Chronic subdural hematoma (CSDH) is a relatively frequent problem in neurologic or neurosurgical practice [1]. The potential for recovery from the evacuation of a CSDH is relatively high. However, some postoperative complications may affect the postoperative course [2]. In this study, we report a rare complication of contralateral acute hematoma following the evacuation of a CSDH with burr-hole craniotomy and continuous closed system drainage. Chronic subdural hematoma (CSDH) is a relatively frequent problem in neurologic or neurosurgical practice. Treatments for CSDH are well established and provide positive postoperative outcome; however, some atypical postoperative complications can occur. This study reports a rare complication of delayed contralateral acute hematoma following the evacuation of a chronic subdural hematoma with burr-hole craniotomy and continuous closed system drainage. According to our research, our study is the first to report a delayed contralateral acute subdural hematoma following CSDH surgery.
