Technique of Percutaneous Direct Needle Puncture of Calcified Plaque in the Superficial Femoral Artery or Tibial Artery to Facilitate Balloon Catheter Passage and Balloon Dilation of Calcified Lesions

Abstract

Heavy calcified arterial lesions are challenging to endovascular treatment. Even if a guide wire passes the lesion, calcified plaque can inhibit passage or dilation of the balloon catheter. We developed a novel technique of percutaneous direct needle puncture of calcified plaque (PIERCE) to allow subsequent passage and dilation of the balloon. PIERCE was performed in three patients with superficial femoral artery (SFA) lesions and one patient with a tibial artery lesion. In all four cases, balloon passage and lesion dilatation were achieved. Minor hemorrhage from the punctured site occurred in two patients with SFA lesions, which resolved with stent placement.
