Tip separation of a Crosser catheter is a serious complication; however, there is limited information on bailout methods. Here, we describe a case of successful retrieval of the separated tip of a Crosser catheter using a 2-wire technique with a gooseneck snare. A 76-year-old woman with a history of hemodialysis and diabetes mellitus who developed ulcers on her right toes was diagnosed as having critical limb ischemia and underwent transfemoral antegrade endovascular treatment of the anterior tibial artery (ATA). A 0.014-inch guidewire was passed through the ATA chronic total occlusion, and then a Crosser catheter was advanced along the wire. During catheter withdrawal, the tip completely detached from the shaft and remained in the ATA. We passed another 0.014-inch guidewire into the distal ATA through the small space beside the tip. A gooseneck snare catheter was advanced to the distal side of the tip along the new wire, and subsequently the 2 wires were entrapped by the snare. The detached tip was finally retrieved with the entire system as a unit and successfully withdrawn into the guiding sheath with no complications. Interventionists should be familiar with the bailout method of this unfavorable complication. Our technique may be widely adapted for various situations involving this complication.
