Arteriography was carried out in 64 cases of pathologically confirmed osteosarcoma to evaluate the angiographic features of this lesion. This investigation proved that a variety of angioarchitectures exist in osteosarcomas, mainly related to the histologic type of tissue as well as the degree of differentiation of a tumor. Fibroblastic and chondroblastic osteosarcomas proved to be less vascular than the osteoblastic type, while the most differentiated tumor appeared to be the least vascular. This technique proved useful in choosing the proper site, or sites, for biopsy as well as for determining the intra- and extraosseous extension of the tumor. Instances were also encountered in which it was of assistance in differentiating osteosarcoma from pathologically similar bone lesions.
对64例经病理证实的骨肉瘤患者进行了血管造影，以评估该病变的血管造影特征。这项研究证明，骨肉瘤存在多种血管结构，主要与组织学类型以及肿瘤的分化程度有关。纤维母细胞型和软骨母细胞型骨肉瘤的血管比成骨细胞型少，而分化程度最高的肿瘤似乎血管最少。这项技术被证明有助于选择合适的活检部位，以及确定肿瘤在骨内和骨外的扩展情况。也有一些情况，它有助于将骨肉瘤与病理上相似的骨病变区分开来。
