title: Influence of tranexamic acid on tumour vascularization. An experimental microangiographic study.
abstract: Administration of tranexamic acid given from tumour transplantation up to sacrifice 5 days later, inhibited the early vascularization of an intramuscularly transplanted rat sarcoma. A marked reduction of angiographically demonstrated vascular connections between tumour and normal muscle was observed. In older, larger tumours an increased frequency of small non-vascularized and probably necrotic tumour areas was suggested after administration of tranexamic acid. An inhibiting effect of tranexamic acid on tumour growth rate has been earlier reported in both experimental and clinical studies. This effect may be explained by an influence of tranexamic acid on tumour vascularization.
