Efficacy and safety of the needle rendezvous technique for infrainguinal arterial calcified lesions.

ABSTRACT:

Background

Lower extremity artery disease is increasingly prevalent, and complex lesions such as calcified chronic total occlusions pose significant challenges during endovascular therapy. The needle rendezvous technique, which involves puncturing a needle toward the guidewire within the lesion or lumen and advancing the guidewire into the needle lumen to achieve guidewire externalization, offers a potential solution. If device passage remains challenging, the Rendezvous-PIERCE technique can be subsequently employed by advancing the needle over the externalized guidewire to modify the lesion directly. This study aimed to evaluate the procedural outcomes of needle rendezvous in infrainguinal arterial occlusive lesions.
