We report the success rate of endovascular therapy (EVT) using a hydrophilic-coated 4.5-Fr low-profile sheathless guiding catheter (Parent Plus45TM; Medikit, Tokyo, Japan) for the infrapopliteal artery by the cross-over approach. Between April 2009 and May 2010, we performed EVT using the Parent Plus45TM for infrapopliteal arteries in 22 lesions in 17 limbs for critical limb ischemia (CLI). This was performed in 15 patients using the cross-over approach. Delivery of the Parent Plus45TM to the popliteal artery of all the patients with CLI who underwent the procedure was successful. The lesion success rate was 95% and the initial success rate was 100%. There were no complications noted. EVT using a 4.5-Fr sheathless guiding catheter for the infrapopliteal artery by the cross-over approach has the potential for a less invasive strategy for the treatment of CLI.
