Clinical value of pre-operative double embolization for nasopharyngeal angiofibroma / 介入放射学杂志

ABSTRACT

Objective To evaluate the clinical value of pre-operative double embolization for nasopharyngeal angiofibroma. Methods Digital subtraction angiography(DSA) was carried out in 7 cases of nasopharyngeal angiofibroma. In six cases,the supplying arteries originated from the maxillary artery and the branches arising from internal carotid artery underwent double embolization-direct percutaneous puncture embolization and selective embolization of blood supplying arteries. In another case,the supplying artery originated from maxillary artery was only undertaken selective embolization for the feeding arteries. Results All the tumor masses reduced in vonlume obviously or even disappeared on the angiography after embolization. Conclusions Pre-operative double embolization for nasopharyngeal angiofibroma could be a necessary additional treatment method. (J Intervent Radiol,2006,15: 342-344)
