[Clinical analysis of selected transarterial embolization in treating uncontrolled epistaxis].

OBJECTIVE

To learn the effects and the correlative factors of selected transarterial embolization in treatment of uncontrolled epistaxis.

METHOD

The abnormal ends of internal maxillary artery were selected embolized in 23 patient of uncontrolled epistaxis by digital subtraction angiography (DSA) of carotid, meanwhile the facial artery were also embolized in 5 patients.

RESULT

It was confirmed that hypogenesis and malformation in the ends of internal maxillary artery were existed in all 23 cases during DSA. There was evidence of bleeding in 15 patients, and facial artery with abnormal shape was found in 6 patients. Nose-bleeding was stopped in 22 cases (95.6%) after embolized, including one had a recurrence of bleeding in 24 hours because of the foundation of new abnormal communications. The fail in one case might be related with taking out all the stuff in noses before embolization and/or bleeding facial artery.

CONCLUSION

Uncontrolled epistaxis in this report might be caused by hypogenesis and malformation of internal maxillary artery. The effects of selected transarterial embolization were rapid and satisfactory. The fail in treatment might be related to foundation of new abnormal communications and bleed from facial artery. Taking out all the stuff in noses too early might also influence the effects of embolization.
