: To present a new and easy technique for performing endarterectomy in patients with peripheral arterial occlusive disease (PAD) having dollop calcification at the common femoral artery (CFA). : We developed a procedure for angioplasty for PAD using a supersonic surgical suction device, based on the new concept of "to create a new lumen to dig tunnel in calcification." Ultrasonic surgical aspiration device was inserted into the intravascular space from outside the area of the target lesion and only internal calcification was removed. : We performed this technique in three patients who had PAD with dollop calcification at CFA. We succeeded in performing endarterectomy easily and safely. This method does not require vascular wall closure suture at calcified lesion or intimal fixation suture of dollop calcification. : We address the technical difficulty in treating highly calcified lesions that could not be dealt with conventional endarterectomy. Our new method is one of the options for revascularization of heavily calcified lesions.
介绍一种针对外周动脉闭塞性疾病（PAD）患者，在股总动脉（CFA）存在团块状钙化时进行动脉内膜切除术的全新且简便的技术。
基于“在钙化灶中挖掘隧道以创建新腔隙”这一新概念，我们研发了一种使用超声外科吸引装置对PAD进行血管成形术的方法。将超声外科吸引装置从目标病变区域外插入血管腔内，仅去除内部钙化。
我们对3例在CFA处有团块状钙化的PAD患者实施了该技术。我们成功轻松且安全地完成了动脉内膜切除术。该方法在钙化病变处无需血管壁闭合缝合，也无需对团块状钙化进行内膜固定缝合。
我们解决了传统动脉内膜切除术无法处理的高度钙化病变的技术难题。我们的新方法是重度钙化病变血运重建的选择之一。
