Objective: To evaluate the vascular architecture of AVM of jaws on DSA.
Methods: 12 cases of AVM of jaws comprised this study group, and 5 cases in maxilla and 7 cases in mandible, respectively. Seldinger technique was applied to carry out carotid angiography under the guidance of DSA machine (PHILIPS V3000).
Results: The DSA features of AVM of jaws included varix into the posterior area of jaws. The varix of the maxilla was supplied by the posterior superior alveolar artery and transversal facial artery when the soft tissue was involved, and the varix of the mandible was supplied by the inferior alveolar artery, maxillary and facial artery.
Conclusion: Angiography is considered necessary for the diagnosis and embolization of AVM of jaws, and the varix is the center of lesion.
