The efficacy of the novel "wall pierce" technique for common femoral access in endovascular therapy.

Key Clinical Message: Under challenging common femoral artery access scenarios, the "wall PIERCE" technique, which utilizes a larger puncture needle to pierce the vessel wall along the guidewire, facilitates sheath insertion. This method proved successful in two cases without any complications, presenting a valuable addition to strategies for addressing challenging sheath insertion scenarios. [ABSTRACT FROM AUTHOR]
