Angiography of Peripheral Tumors

Tumors vary widely in vascularity, most of them containing fewer but some, more blood vessels than the corresponding normal tissue. Some fifty years ago German pathologists found that the malignant mesenchymal tumors, or sarcomas, in particular, are highly vascular and the higher the malignancy the greater the vascularity. At the end of the 1920s the first radiologic examination of blood vessels involving injection ot contrast medium was performed in Portugal, and this technic was found to be a useful aid in study of the vascular supply of tumors. Dos Santos (9) proposed certain angiographic criteria of malignancy, notably the presence of numerous irregular vessels at the periphery of the tumor and a rapid transit of the contrast medium from the arteries to the veins. Material and Methods Angiography of peripheral tumors has been performed in our department since 1941, and the frequency of such examinations has increased in recent years. The material of tumor and/or tumor suspects submitted for angiograp...
