[The value of intra-osseous angiography for primary, malignant bone tumours (author's transl)].

By means of intra-osseous angiography, it is possible to demonstrate abnormal vascularisation, the vascular pattern of osteolytic sarcomas differing markedly from that of osteoplastictumours. Important information can be obtained regarding the close relationship between tumour vessels and the parosteal soft tissue vessels. The close relationship between these provides ample explanation for the early occurrence of haematogenous metastases. The extent of the intramedullary tumour component of chondrosarcomas can also be demonstrated.
