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.
严重钙化的动脉病变对血管内治疗具有挑战性。即使导丝通过病变部位，钙化斑块也可能阻碍球囊导管的通过或扩张。我们开发了一种经皮直接穿刺钙化斑块的新技术（PIERCE），以允许随后球囊的通过和扩张。对3例股浅动脉（SFA）病变患者和1例胫动脉病变患者进行了PIERCE操作。在所有4例病例中，均实现了球囊通过和病变扩张。2例SFA病变患者穿刺部位出现轻微出血，放置支架后出血停止。
