CT-controlled stereotactic operationによる高血圧性脳内血腫除去術—その2：視床ならびに大脳基底核部の小血腫除去例

CT-controlled Stereotactic Operations for Hypertensive Intracerebral Hemorrhage:Part 2:Cases with small hematomas in the thalamus and the basal ganglia

I．はじめに

　われわれは最近，CT（computed tomography）装置に松本式定位脳手術装置を組み込み，術中CT scanを行って得られた画像から直接立体座標を得て，穿刺針の方向を修正し，またその深さを求めて，意図する手術目標点に達するという，いわば，"CT-controlled stereotactic　operation"とでもいうべき手術法を考案した．このための手術の理論と手術術式については前編で報告した^12）．これにひきつづき，本稿では，この手術を実際に行った9例の視床および大脳基底核部の小血腫例について，その臨床経験を報告するとともに，このような小血腫の手術適応，手術時期，機能予後などについて若干の検討と見解を加え報告する．

Theoretical principles and actual operative pro-cedures of "CT-controlled stereotactic operations," which was invented by us, have been reported in the previous paper of part 1.

In this paper, it is reported 9 cases, 5 of putaminal hemorrhage and 4 of thalamic hemorrhage, who underwent CT-controlled stereotactic operations for evacuation of their small hematomas. Eight patients were male and one patient was female. The age of patients ranged from 42 to 75 years, with a mean age of 62.7 years and there were 3 patients of over 70 yearsold.
