  • Title: Strategies to Minimize Iodinated Contrast Volume in Patients with Chronic Kidney Disease Undergoing Peripheral Vascular Interventions.
    Author: Lee SR, Dardik A, Chaar CIO.
    Journal: Ann Vasc Surg; 2021 May; 73():490-495. PubMed ID: 33556507.
    Abstract:
    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 CO2 and dilute ICM (total volume = 6.5 mL). The case demonstrates strategies to minimize ICM during PVIs.
