A case of a femoropopliteal recanalization procedure using a new bailout technical maneuver to aid reentry into the true lumen is described. After a failed standard reentry attempt, at the level of the vessel reconstitution in the subintimal space, the guidewire was exchanged for a GooseNeck Snare Kit. A needle was inserted across the target artery, piercing both arterial walls and passing through the snare loop. Once the needle had exited the artery, a wire was inserted and the needle withdrawn. The snare was closed, withdrawn, and the wire externalized through the femoral access. Finally, a catheter was advanced from the antegrade sheath up to the arterial reconstitution. Selective injection at the site of reentry confirmed the intraluminal position, and the procedure was successfully completed from the antegrade sheath.
