The evidence-based evaluation of the safety of contrast media in patients with diabetes mellitus / 介入放射学杂志

ABSTRACT

Contrast-induced nephropathy (CIN) has now been the third most common cause of acquired renal failure. Diabetes mellitus (DM), the type of contrast agent used and the intra-arterial route of administration are three important risk factors inducing CIN. The incidence rate of CIN is very high in patients with DM or renal insufficiency after iodinated contrast was administered. Unfortunately, it has not yet attracted physicians’and radiologists’sufficient attention. This paper aims to make an evidence-based evaluation of the safety and rephrotoxicity of various contrast agents when they are used in patients with DM. Usually, intravenous administration of contrast media will not cause permanent damage to the kidney in highrisk patients. Low-osmolarity contrast media is relatively safe for patients with DM only, while it takes much risk of CIN when low-osmolarity contrast media is used in patients with diabetic nephropathy or in patients of DM accompanied with renal insufficiency, for such patients, the iso-osmolarity contrast media, iodixanol, can be used.
