AbstractSubdural haematoma is a well-documented complication of accidental dural puncture, and is thought to be preventable by prompt treatment with an epidural blood patch. An accidental dural puncture occurred in a 39-yr-old primagravida during the siting of an epidural catheter for pain relief in labour. Twenty hours after the puncture, the mother developed a typical postdural puncture headache, which increased in severity over the subsequent 24 h. An epidural blood patch was performed at 48 h, and this initially relieved the headache. After discharge from hospital, and 14 days after the dural puncture, the headache recurred, together with expressive dysphasia, poor co-ordination and sensory loss in the right arm. A magnetic resonance imaging scan demonstrated a left sided subdural haematoma, which was drained successfully with complete recovery.
