作者四年来曾对6例第三脑室扩展性病变,采用经丘脑穹窿间进路,显露良好,便於手术,特报导如下: 打开侧脑室采取的途径有二:1.于半球间经胼胝体进路,对大脑的损伤小,但需切断胼胝体间联合,且有在中央回区域发生皮质脑膜静脉输入阻断的意外危险,故不如下一途径奸。2.经一例大脑皮质凸面行皮质切开术——于右侧大脑半球,离内缘 The author of the past four years had 6 cases of third ventricle expansion lesions, the use of the interhemispheric intervertebral approach, showing good, easy to operate, especially reported as follows: open the lateral ventricle to take the two ways: 1. In the interhemispheric corpus callosum approach , The damage to the brain is small, but the need to cut off the corpus callosum joint, and in the central back-cortical venous occlusion occurred in the risk of accidental closure, it is not as bad as the next route. 2.
