定位的開頭術を応用した海綿状血管腫の1例

A Case Report of Stereotactic Craniotomy for the Cerebral Cavernous Angioma

Ⅰ．はじめに

　脳内占拠性病変を摘出する際に，いかに後遺症なく正確に摘出するかは大きな問題である．現在では術中エコー，術中モニタリング，手術ナビゲーション，手術シミュレーションなどの方法が主として用いられている．今回われわれは左側頭葉深部に発生し，出血を来した海綿状血管腫に対して駒井式定位脳手術装置を使用した定位的開頭術を行い，良好な結果を得た1例を経験したので，若干の文献的考察を加えて報告する．

　A 59-year-old woman presented with right sensory loss and right hemiparesis. In February 2013, she was admitted to Araki Neurosurgical Hospital. A magnetic resonance imaging was performed that revealed a left temporal lobe hemorrhage. The image also showed a chronic stereotype hematoma. After 14 days of hospitalization, she underwent a stereotactic craniotomy. Subsequently, by postoperative pathological evaluation, the hematoma was diagnosed as a cavernous angioma. She had no postoperative complications. She was provided rehabilitation support and was discharged 28 days after the admission following which she rejoined work. A stereotactic craniotomy device is very useful in surgeries involving deep lesions. We present a case of stereotactic craniotomy and a few investigation reports.
