Intracranial subdural hematoma is an exceptionally rare complication of spinal anesthesia. An 88-year-old female patient diagnosed with grade Ⅴ uterine prolapse with rectocystocele received a vaginal hysterectomy and anteroposterior repair under spinal anesthesia. At 4 days postoperatively, she appeared to have decreased orientation, inappropriate behavior, and right side weakness grade Ⅲ. Brain MR diffusion and CT revealed a bilateral subdural hematoma. She was improved after burr hole drainage. We report a case of intracranial subdural hematoma developing after spinal anesthesia, a rare complication.

A new surgical method for the treatment of chronic subdural haematoma is presented. A small craniostomy is made on the superior lateral angle of the forehead just beneath the hair line without hair removal using a high-speed drill. Through this aperture, evacuation and irrigation of the haematoma can be carried out safely. No infections occurred in a series of patients treated in this way, and the recurrence rate was 10% (2/20). The surgical wound was negligible. Because of its simplicity, and the lack of a need for hair removal, the procedure appears to be acceptable as an optional therapeutic modality.
