A case of successful intervention without a contrast agent for a chronic totally occlusive lesion of the superficial femoral artery

Peripheral artery disease (PAD) and chronic kidney disease (CKD) commonly occur together and are known to lead to poor long-term survival. Furthermore, it is not yet known whether percutaneous catheter intervention for PAD using contrast agents is beneficial or not for such patients. The risk of CKD patients contracting contrast-induced nephropathy due to the use of contrast agents is frequent. We report a patient with diabetes and CKD in whom a chronic total occlusion lesion of superficial femoral artery was successfully managed with catheter treatment without the use of contrast agents, using various modalities.
