Digital subtraction angiography and selective external carotid embolization in the diagnosis and treatment of maxillofacial tumor / 实用口腔医学杂志

ABSTRACT

Objective:To study the feasibility of digital subtraction angiography(DSA) and selective external carotid embolization(SECE) in the diagnosis and treatment of maxillofacial tumor. Methods: DSA features, embolotherapy, clinical treatment and complications were investigated retrospectively in 22 cases diagnozed by means of DSA and treated with SECE. Results: After embolization, the bleeding was completely stopped in two cases with emergent hemorrhage, the tumor was shrunk in one case with central hemangioma in maxilla three weeks later and the bleeding in operation was reduced significantly. The tumor boundary was clear for tumorectomy in all the other cases. No recurrence was observed in 3-year-follow up. Conclusion:DSA and SECE are safe, optimal and effective in the treatment of maxillofacial tumour and hemorrhage.
