RESUMO
Objective： To study the application of DSA in the diagnosis and treatment of ENT diseases. Methods： The diagnostic and therapeutic roles of DSA in ENT patients admitted from November 1995 to December 1999 were retrospectively studied. Results： Therapeutic vascular embolization using DSA was performed in 9/10 patients with severe epistaxis. The treatment was successful in 8/9 patients with a successful rate of 88.89%; embolization of tumor supplying vessels using DSA as a preoperative measure for reducing operative blood loss in 3 patients with nasopharyngeal fibrohemangioma obtained a total success; diagnosis was clarified in 2 patients using DSA. No patients were with severe complications. Conclusion： DSA is not only a safe and effective measure for diagnosis and therapy, but also effective in differential diagnosis of space occupying lesions. Preoperative selective embolization of tumor supplying arteries can reduce operative blood loss.
