Endovascular Therapy Using a 4.5-Fr Sheathless Guiding Catheter for the Infrapopliteal Artery by the Cross-over Approach

Abstract

We report the success rate of endovascular therapy (EVT) using a hydrophilic-coated 4.5-Fr low-profile sheathless guiding catheter (Parent Plus45^TM; Medikit, Tokyo, Japan) for the infrapopliteal artery by the cross-over approach. Between April 2009 and May 2010, we performed EVT using the Parent Plus45^TM 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 Plus45^TM 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.
