A, Lateral projection of the left superficial temporal arteriogram demonstrates a fistulous CHVM; there is attenuated opacification of the draining vein, which projects in between the 2 branches of the artery.
B, Floroscopic image captured during percutaneous embolization shows impediment of venous filling by the external compression over the vein with a hemostatic clamp; retrograde filling in numerous arterial pedicles is also noted.
C, Postprocedure external carotid injection in lateral projection demonstrated no evidence of a residual lesion.
D, Postembolization photograph demonstrates blackish discoloration at the injection site.
E, Photograph after resection of the cast on postoperative day 5 shows residual discoloration at the margins of the incision.
