Objective: To make a further understanding of the DSA features of the carotid body tumor (CBT) and to explore the clinical value of DSA diagnosis and interventional treatment for CBT. Methods: Twelve cases of CBT with DSA data were analyzed retrospectively. The DSA appearances in all of the patients were observed dynamically in a double blind manner by two experienced radiologists together and a consensus interpretation formed. Results: DSA could establish definitive diagnosis in all cases. The DSA features of the CBT were: the increase of bifurcation angles of internal and external carotid arteries in all cases; the CBT supplied by external carotid arteries in most cases and the significant increase of tumor vessels in bifurcation; invasion of internal or external carotid arteries in 6 cases. The tumor staining disappeared mostly after the supplying arteris were embolized in 2 cases, and the bleeding during the operation reduced significantly. Conclusion: The DSA is useful in the diagnosis of the CBT and for therapeutic planning. The pre-operation embolization of the CBT contributes to reduce the bleeding during operation.
