Procedure diagram of recanalization using the landmark-wire technique and a protective device in the vertebral artery via the brachial artery. We assumed that the stent covered the vertebral artery ostium because retrieval of the protection device would be difficult in a case of such jailing. The left subclavian artery occlusion (A) with patent vertebral artery lumen was probed using a stiff guidewire (B). Stenting was performed with a protective device in the vertebral artery. Note the retrieval catheter already positioned in the vertebral artery in order to smoothly remove the protective device (C, D).
