title: [Angiographic study of osteosarcoma and fibrosarcoma of the jaw].
abstract: It has been well known that the sarcomas of jaw are very vascularized, but reports on the angiography of jaw sarcomas were very few. Based on the preoperative angiography of 3 cases of jaw bone sarcomas and arteriography of their specimens, it has been noticed that the supplying arteries of the mandible ramus sarcoma can be directly from the external carotid arteries; and the supplying arteries can be from inferior alveolar artery in sarcomas of the body of mandible. The tumors are more vascularized than the surrounding normal tissues, and the direction of the arteries can be from central to peripheral in the tumors, which are different from the long bone sarcomas. The vascularization and the retarded blood flow in the tumor are the significant anatomic bases for local perfusion chemotherapy of jaw sarcomas.
