[Arteriographic findings in bone tumors: experience with 170 cases].
From September 1978 to June 1987, arteriography was performed respectively in 62 cases of osteosarcoma, 21 cases of giant cell tumor and 87 cases of other benign or malignant of bone tumors. In 7 cases contrast medium was injected through indwelling catheter in all other cases it was injected by direct puncture which we think should be of first choice. Arteriographic findings in osteosarcoma were neovascularity and hypervascularity (98.5%), tumor staining (56.4%), early venous drainage (48.3%), arterial displacement (67.7%), and arterial caliber changes (50.1%). Some of the features were more prominent in certain types of osteosarcoma, such as tumor staining was mostly seen in osteolytic osteosarcoma. The arteriographic findings of other malignant bone tumors were similar to those of osteosarcoma. Malignant angioarchitecture usually was not found in benign tumors, but displacement of the artery may be occasionally seen. Extraskeletal part of osteosarcoma and giant cell tumor cannot be shown clearly in plain X-ray film, but it could be clearly seen in angiography. Usually, the extraskeletal part in osteosarcoma is larger than that in giant cell tumor.
