 A 64-year-old woman with right subclavian artery injury by an inadvertent puncture. A Pre-treatment angiogram shows extravasation from the proximal site of the right subclavian artery (arrows). The right vertebral artery branches close to the extravasation (arrowheads). B After confirming that the contralateral vertebral artery is patent and joins the ipsilateral vertebral artery, the right vertebral artery is embolized by coils (arrows) to avoid type 2 endoleaks under balloon occlusion (arrowhead) of the right subclavian artery. C Angiogram after endovascular therapy with Viabahn stent grafts (8 mm × 5 cm and 8 mm × 10 cm) shows the disappearance of the extravasation without endoleak
