Embolization and sclerotherapy of maxillofacial arteriovenous malformations with the use of fibrin glue combined with pingyangmycin.

OBJECTIVE

The objectives of this study were to document the results of using fibrin glue (FG) combined with pingyangmycin (PYM) for the embolism and sclerotherapy of maxillofacial arteriovenous malformations (AVMs).

STUDY DESIGN

We reviewed the associated clinical data from December 2012 to June 2017 for 25 patients with maxillofacial AVMs. The major treatment method was direct percutaneous puncture and injection of FG combined with PYM. Treatment outcomes were assessed through physical examination, Doppler ultrasonography, computed tomography, and 3-dimensional computed tomography angiography scans. Follow-up time ranged from 12 months to 3 years after the last treatment (mean 21 months).

RESULTS

Of the 25 lesions, 80% showed greater than 90% reduction, 12% showed greater than 75% reduction, and 8% showed greater than 50% reduction. Superficial skin necrosis or mucous ulcer occurred in 3 patients and healed without intervention. Regrowth was observed in 3 patients with extensive lesions involving multiple anatomic regions.

CONCLUSIONS

These data suggest that embolization and sclerotherapy with the use of FG combined with PYM are safe and effective for the treatment of small- to medium-sized, locally dilated maxillofacial AVMs. For AVMs involving multiple anatomic regions, combined application of this approach with other options should be considered.
