The process of the “needle rendezvous” of the “needle re-entry” technique. A. The retrograde microcatheter in the distal lumen below the dilated antegrade 5.0-mm balloon in the subintimal plane was confirmed in ipsilateral view. B. These devices were overlapped in contralateral view. C. An 18-gauge needle was inserted from the distal thigh to the dilated balloon. After confirming a balloon rupture by the needle penetration, the needle was continued to advance to meet the retrograde guidewire tip. D. A retrograde 0.014-in. guidewire was carefully manipulated and successfully advanced into the needle hole
