Treatment of the recanalization of maxillary and mandibular arteriovenous malformations in children.

OBJECTIVE

This study reviewed our experience in treating the recanalization of maxillary and mandibular arteriovenous malformations in children.

STUDY

DESIGN

Four patients with maxillary or mandibular arteriovenous malformations (AVMs) were included in this study. All the patients had undergone multidisciplinary treatment of AVM at least 26 months before our review, including superselective intra-arterial embolization combined with bone wax packing. Computed tomographic angiography and digital subtraction angiography were performed to confirm the presence of recanalization. Superselective intra-arterial embolization combined with bone wax packing and tooth extractions were performed in the patients with recanalization.

RESULTS

After confirmation of the recanalization of AVM by digital subtraction angiography, the patients were treated with superselective intra-arterial embolization combined with bone wax packing and tooth extractions (if necessary). All the patients were followed up for 5 to 14 months, with an average of 9.5 months. The outcome for all patients was good, and no patient complained of pulsatile sensation or hemorrhage after treatment.

CONCLUSIONS

In the treatment for recanalization of maxillary and mandibular AVMs, reapplication of the superselective intra-arterial embolization, combined with bone wax packing, remains necessary.
