Strategies to Minimize Iodinated Contrast Volume in Patients with Chronic Kidney Disease Undergoing Peripheral Vascular Interventions.

Peripheral vascular interventions (PVI) utilize iodinated contrast medium (ICM) to visualize intravascular lesions and guide therapy. The use of ICM carries a risk of postcontrast acute kidney injury (PC-AKI), which is increased in the elderly and in patients with chronic kidney disease (CKD). Furthermore, the risk of PC-AKI increases with the volume of ICM used. This paper reports a 94-year-old patient with CKD stage 4 who presented with chronic limb threatening ischemia. He underwent successful endovascular revascularization using a combination of CO and dilute ICM (total volume = 6.5 mL). The case demonstrates strategies to minimize ICM during PVIs.
