Superselective arterial embolization in otorhinolaryngology: Indications and complications in a 12-year experience

Abstract

Introduction. Arterial embolization is an invasive procedure that results beneficial in numerous otorhinolaryngological pathologies. It is mainly indicated as the primary therapy or as a presurgical adjuvant in vascular head and neck tumors . Its complications are not infrequent and require early assessment. Aim. To analyze the otorhinolaryngology superselective arterial embolization experience in our clinical department. Material and Method. This is a retrospective study. Procedures performed between 1995 and 2007 were analyzed. The group was characterized considering diagnosis, indications and complications derived from the procedure. Results. A total of 23 procedures performed in 18 patients was studied. 95.6% (n=22) were carried out as presurgical adjuvant therapy in the treatment of vascular tumors, and 4.4% (n=1) as primary treatment for intractable epistaxis. Complications were found in 21.7% of patients, with a general incidence of 17.4% (n=4) due to minor complications and 4.3% (n=1) due to major complications. Conclusion. Presurgical arterial embolization is recommended in highly vascular head and neck tumors because of the surgical benefits it reports. Complications are mostly minor; major complications being infrequent, but with high impact on the patient. It is thus a useful and safe tool in selected patients, when trained radiologists and adequate materials are available.
