C．T．による被殼出血の分類と外線状体動脈の動き

Classification of Intracerebral Hematoma (Lateral Type) on C.T. and its Relation to the Shift of the Lenticulostriate Arteries

Ⅰ．緒言

　高血圧性脳出血，特にその被殻出血の分類と診断についての報告は数多い^2，4，5）．しかし最近のC．T．（computed tolnography）による分類およびそれと脳血写所見との対比，および片麻痺の予後との相関を見た報告を著者はいまだ見ていない．

　一方，C．T．は高額のためいずれの施設でも備えるわけにはいかず，その意味で脳血写所見との相関々係を確立することは意味あることと老える．著者らは被殻出血では，これを外線状体動脈の変化に求め検討した結果，以下のごとき若干の知見を得たので報告し，諸賢の御批判をいただきたい．

Classification of intracerebral hematoma (lateral type) with C.T. was tried. And also, the relationship among the location of the hematoma, the shift of the lenticulostriate arteries and the prognosis of hemiparesis was verified.

The results were as follows;

1) The location of the hematoma was classified into four types:

1. anterior type (the hematoma mainly located in the anterior limb of internal capsula).

2. Posterior type (the hematoma mainly located in the posterior limb of internal capsula).

3. lateral type (the hematoma mainly located just below the insula).
