- Fig 1.
Preoperative angiogram with LECA and LVA injections showing a posterior fossa DAVF with feeders from the left occipital artery and the muscular/meningeal branches of the LVA, with a single large draining cortical vein. The patient underwent partial embolization of the fistula, and it was decided to treat the remaining portion of the fistula with surgery.

IA (left) showing no residual fistula. Postoperative angiogram, LECA and LVA injections, shows no residual fistula.

Preoperative left ICA injection, lateral projection showing a CCF. Following an unsuccessful attempt at endovascular treatment, it was treated surgically. The first IA shows evidence of residual fistula, after which the surgeon further packed the cavernous sinus. The second intraoperative angiogram and a postoperative angiogram show no evidence of residual fistula.
