急性硬膜下血腫の減圧開頭術後に合併した外傷性水頭症の1例

A Case of the Traumatic Hydrocephalus after Large Craniectomy for Acute Subdural Hematoma

Ⅰ．はじめに

　減圧開頭術後に神経症状の脱落が出現し，頭蓋形成術を行うことで症状が改善することは臨床上しばしば経験することであり，the syndrome ofthe sinking skin flap^15），やthe symptom of the tre-phined^1,3），などとして知られている．

Decompressive craniectomy sometimes causes neurological deficits known as 'the syndrome of the sinking skin flap' or 'the symptom of the trephined'. These disorders can be corrected with cranioplasty, but there is no consen-sus on appropriate treatments. We report a case of successful correction of traumatic hydrocephalus following crani-otomy.

A 50-year-old man was admitted to our hospital with disturbance of consciousness after a head injury. Decompres-sive craniectomy was performed for a right acute subdural hematoma.
