FINISH-trial is a prospective, randomized, controlled, parallel group non-inferiority trial comparing single burr-hole evacuation of chronic subdural hematoma (CSDH) with intraoperative irrigation (IR) and evacuation of CSDH without irrigation (N-IR). In both groups, a passive subdural drain is used for 48 hours as a standard of treatment. The study will be conducted in all five neurosurgical departments in Finland. To determine whether operation without irrigation results in non-inferior outcome to operation with irrigation, we will randomize 426 patients into two groups and follow them up for 6 months using recurrence rates as the primary outcome. Secondary outcomes in our study include mortality, neurological outcome and complications.
