Today, lower limb arteriography with bilateral common iliac artery stenting was performed under local anesthesia. The patient was lying down and the left femoral artery was punctured. The intraoperative angiogram revealed no stenosis or torsion of the bilateral renal arteries, the right common iliac artery had a stenosis of about 55％ and a significant plaque was seen. The distal anterior tibial artery and the tibiofibular trunk were well visualized; it was decided to perform bilateral common iliac artery stenting: a right femoral artery puncture was also performed at the body projection of the right inguinofemoral artery, and after a successful procedure, a short 7F sheath was placed and a 0.018F guidewire was introduced through it, and a small intravenous pot was given 50 mg of heparin for systemic heparinization. After the imaging showed ROADMAP, a 10-40 mm self-expanding stent of Cordis PRECISETMNitinol Stent System was introduced through the guidewire, which was released smoothly and the stent completely covered the stenotic end, and then the stenosis was dilated with an 8-40 mm POWERFLEX P3 balloon, and the imaging showed that the stenosis disappeared. The left common iliac artery was stented in the same way, and the imaging showed good dilation of the left common iliac artery. A short sheath was left in place and the patient was returned to the ward. The operation went smoothly and the patient had no complaints of discomfort during the operation. Postoperative management: After the ACT was nearly normal, the short sheath was removed.
