Treatment of mandibular arteriovenous malformation by transvenous embolization: A case report
1Department of Radiology, Oita Medical University, 1-1 Hasama, Oita, Japan.
Background:
Arteriovenous malformations (AVMs) of the mandible are relatively rare and potentially life-threatening lesions. Treatment is usually difficult. This study presents a case with high-flow AVM of the mandible in which most of the AVM were occluded by transvenous coil embolization.
Methods:
Transvenous embolization using several size 57 microcoils and 3 Gianturco coils was performed through a right femoral vein access. The small residual AVM was occluded by superselective transarterial injection of cyanoacrylate.
Results:
Angiography after embolization showed almost complete obliteration of AVM. Panoramic radiograph 2 years after treatment confirmed reossification. There was no recurrence of the symptoms in a follow-up evaluation 2 years later.
Conclusion:
Transvenous coil embolization may be a safer and more effective method in the treatment of mandibular AVM.
