[Classification of intracerebral hematoma (lateral type) on C.T. and its relation to the shift of the lenticulostriate arteries (author's transl)].
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). 4. spread to the all direction type. 2) The lenticulostriate arteries was divided into three portions: L1 portion is the part from the origin at the middle cerebral artery to the knee point, L3 is the part of the distal portion of the lenticulostriate arteries, and L2 portion in the part between L1 and L3 portions. L1 portion was mainly shifted medially in the anterior type of the hematoma. L2 portion was mainly shifted medially in the lateral type of the hematoma. L3 portion was mainly shifted in the posterior type of the hematoma. L1, L2, L3, all portions were shifted medially in the type in which the hematoma spread to all directions 3) The prognosis of the hemiparesis was best in the lateral type of the hematoma, and next in the anterior type. In the posterior type and all spread type, it was worst.
