Dural AVF Embolization-Tortuous Access: Wire Loop Technique
A 58-year-old male presented with sudden-onset weakness of the right lower limb. MRI revealed a small bleed adjacent to motor cortex. A large flow void was seen adjacent to the bleed along with multiple dilated serpiginous vessels in adjacent sulcal spaces (Fig. 65.1a). DSA revealed a dural arteriovenous fistula in the left frontoparietal region with feeders from bilateral middle meningeal and left superficial temporal arteries (Fig. 65.1b–f). Marked tortuosity of the feeder vessels and venous congestion was noticed. The case was planned for transarterial Onyx embolization.
