  Fig. 1. A vertebro-vertebral fistula was detected on the preoperative coronal plane computed tomography angiography image in case 1 (arrows, A). This fistula was confirmed on digital subtraction angiography images (arrows in B and C). The fistula was closed with the Woven EndoBridge device (arrow, D). Preoperative (E, G, I) and postoperative (F, H, J) 3-tesla magnetic resonance angiography (time-of-flight, TOF) images of the case. The dilated venous drainage around the right V3 segment of the vertebral artery due to the fistula is depicted on preoperative TOF data. The fistula and enlarged veins are no longer observed after endovascular intervention. The final examination showed a normalized posterior circulation.
