Subdural hematoma as a late complication of spinal anesthesia

Abstract

Subdural hematoma is a rare complication of spinal anesthesia. This patient underwent bilateral inguinal herniorrhaphy under spinal anesthesia 40 days prior to admission. Two days after spinal anesthesia, the patient described a typical postdural puncture headache. Oral analgesics, fluid therapy, and lying flat were recommended. Because of prolonged headache, computed tomography scan was performed and demonstrated chronic subdural hematoma in the left fronto-temporo-parietal region. After surgical drainage, the patient fully recovered. Prolonged headache should be regarded as a warning sign of subdural hematoma.
