外傷性基底核部出血の1例:超音波誘導穿頭血腫ドレナージ術による治療例

A case of traumatic hematoma in the basal ganglia:succesful drainage with ultrasound-guided aspiration surgery via burr hole

I．はじめに

　外傷性基底核部出血は，CT scan導入により報告例も増加しており，孤立性のもの^7,16,20）と他の部位の出血巣を随伴するものとがあり^4,9,10,16），臨床的には異なった像を呈する．本稿では外傷性基底核部出血に対し，穿頭用超音波プローベを用い，超音波ガイド下血腫吸引術を施行し，良好な経過をたどった症例を経験したので報告する．

A case was reported of massive traumatic hematoma of the basal ganglia which was treated succesfully by ultrasound-guided aspiration surgery.

A 8-year-old girl was transferred to our hosiptal 20 minutes after a traffic accident. She was in stupor and had right hemiplegia. A skull x-rays showed right tem-poral linear fracture and a head CT disclosed left mas-sive putaminal hematoma. Ultrasound-guided aspiration surgery via a burr hole was performed under general anesthesia and 30ml of hematoma was successfully evacuated. Her symptoms and signs improved gradually and she was discharged on foot 3 weeks after the acci-dent. The clinical feature and mechanism of develop-ment of the hematoma in this lesion, and usefullness of ultrasound-guicied aspiration surgery were also discuss-ed.
