Fig 1. A, Lateral view from a left internal carotid angiogram demonstrates rapid filling of a large pseudoaneurysm (arrows), with subsequent drainage into the ipsilateral sigmoid sinus (curved arrow) and retrograde opacification of the superior ophthalmic veins (arrowheads). Note the lack of any opacification of normal carotid artery distal to the site of the fistula.
B, Lateral view from left common carotid artery angiogram after treatment of the carotid cavernous fistula (data not shown) and after glue embolization of the distal cervical ICA demonstrates a small amount of residual filling of the pseudoaneurysm (arrows) from a branch of the left internal maxillary artery (arrowhead).
C, Lateral view, left common carotid angiogram after embolization of the internal maxillary artery branch demonstrates no further filling of the pseudoaneurysm or the fistula.
