To evaluate the traditional chinese medicinal agent Bletilla Striata used as arterial embolizing agent for treatment of bony neoplasma.Materials and methods:6 patients with osteoblastoma,chondroblastoma,fibrosarcoma with bony metastasis,bronchial carcinoma with pelvic metastasis,chordoma,and fibrous dysplasia respectively were treated by arterial embolization using Bletilla Striata. The follow-up controll was made by angiography,clinical examination,X-ray film and pathological study after operation. Results:Serious pain was reduced significantly in 3 patients;Calcification was noted in the lesions in 2 cases;Pathological examination showed large area of necroses in tumor after embolization;Angiograms showed obliteration of supplying vessels in the tumor in 1 month.The patient with fibrosarcoma,who had been operated on before embolization but it was failed because of incontrallable bleeding,has been operated successfully after embolization.
