Effect analysis of interventional therapy for hemorrhage of mandibular arteriovenous malformations / 中华放射学杂志

ABSTRACT

Objective@#To explore the therapeutic value of interventional methods for hemorrhage caused by mandibular arteriovenous malformations.@*Methods@#The clinical data of 7 patients (3 males and 4 females) with mandibular arteriovenous malformations treated by interventional therapy from January 2012 to January 2018 in the First Affiliated Hospital, Zhengzhou University were retrospectively analyzed. Of all patients, 4 patients suffered from sudden massive hemorrhage and 3 patients suffered from spontaneous repeated bleeding. The age ranged from 8.0 to 13.0 (10.6±1.7) years. Of the 7 patients, 3 underwent interventional embolization via arteries and veins, and 4 underwent embolization only via arteries. The embolic materials were polyvinyl alcohol granules and coils. The follow-up period was 9—18 months and the curative effect was observed.@*Results@#Among the 7 patients, 4 cases of acute massive hemorrhage were effectively controlled after interventional operation, 3 cases of chronic bleeding disappeared after interventional operation. No recurrence of bleeding occurred during the follow-up period, only 1 patient presented with oral infection and gingival swelling and hyperplasia. The symptoms were effectively controlled after anti-infection and debridement. No severe complications occurred in all patients.@*Conclusion@#Interventional therapy for ateriovenous malformation with hemorrhage is effective, safe and feasible, which is worthy of clinical application.
