Clinical observation on 41 cases of threatened and habitual abortion treated by blood activation and stasis removal.

41 cases of pregnancy diagnosed as belonging to 4 subtypes of blood stasis, namely, qi stagnant, qi deficient, pernicious cold condensing and heat accumulating, suffering from womb leak, stirred fetus and fetal slip (threatened and habitual abortion) were treated by the method of blood activation and stasis removal in accordance with diagnostic typing. The treatment proved effective in 34 cases, the effective rate reaching 82.9%, with no significant differences either between threatened and habitual abortions or among the groups of cases with different syndromes. The treatment resulted in varying degrees of improvement in blood rheology and the level of serum (human) chorionic gonadotropin (HCG). Follow-up examination of 28 patients who had reacted favorably to the treatment and whose pregnancy had ended in normal deliveries revealed that none of the newborns differed significantly from the normal.
