11 cases of acute cerebral thrombosis were treated with a combination of venesection (400-800 ml of blood being let out at a time) and administration of an equal volume of low-molecular weight dextran solution Thereafter 500 ml of the dextran solution was given to each patient every day for 15 days. A comparison was made between this group and another group of patients who received just dextran. In the venesection group the mean value of hemoglobin was reduced from 15 g% to 13 g%, that of hematocrit from 44.6% to 40%, and that of the whole blood viscosity from 5.15 to 4.40. The neurological scores showed marked changes after three days of venesection. On the 21st day the scores in the venesection group increased by 31.6% (20.1 points) and that in the control group increased by 12.6% (7.7 points). Evidently the venesection group resulted in much better recovery (P less than 0.001).
11例急性脑血栓形成患者采用放血疗法（每次放血400 - 800毫升）并输注等量低分子右旋糖酐溶液进行治疗，之后每天给每位患者输注500毫升右旋糖酐溶液，持续15天。将该组患者与另一组仅接受右旋糖酐治疗的患者进行比较。放血组血红蛋白平均值从15克%降至13克%，红细胞压积从44.6%降至40%，全血粘度从5.15降至4.40。放血三天后神经功能评分出现明显变化。在第21天，放血组评分提高了31.6%（20.1分），而对照组提高了12.6%（7.7分）。显然，放血组的恢复情况要好得多（P小于0.001）。
