faciale arteriovenous malformations

The role of

combined computed tomographic angiography and digital subtraction angiography in the management of cervico-facial vascular lesions. Male patient presented by a pulsating left-sided upper oral cavity lesion. a A real photo showing bulging bluish lesion in the left side of the oral cavity. b Axial and sagittal (MIP image) sections of CTA revealing a left-sided buccal AVM. c DSA showing the palatine AVM using the macro-catheter in lateral and AP projections. d DSA showing the palatine AVM using the micro-catheter in lateral and AP projections. e DSA showing the glue material within the AVM which is apparently occluded at post-embolization angiogram super-selectively via the facial artery. f Another DSA image showed a reisdual active small component (red arrow) nearby the occluded component (green arrow). g The last post-embolization angiogram showing total obliteration of both components of the AVM after superselective catheterization of the feeding branch of the facial artery. h Non-contrast CT axial and sagittal images showing the retained glue material within the nidus of the AVM after successful embolization
