ABSTRACT
I report two cases of subchorionic hematoma successfully treated with Tokishakuyakusan. They had genital bleeding due to subchorionic hematoma in the second trimester of pregnancy. I prescribed Tokishakuyakusan, and their genital bleeding improved within a week after the administration. The hematoma disappeared in less than two weeks after the administration, and they delivered infants of 2470g and 3324g respectively at 39 weeks pregnant by vaginal delivery. I found Ketsu stagnation, Sui disturbance and coldness of extremities in two cases. Although several studies suggested that the presence of subchorionic hematoma might be associated with adverse pregnancy outcome, there is no effective treatment for subchorionic hematoma in western medicine. The present cases suggest that Tokishakuyakusan may be useful in the treatment of subchorionic hematoma.
