The first experience of using carboxyangiography in renal denervation in a patient with resistant arterial hypertension, chronic kidney disease and iodine contrast allergy

Traditionally an iodine-containing contrast agent is used for renal arteries angiography. However, patients with chronic kidney disease (CKD) and allergic reaction to iodine, despite infusion and desensitization therapy, have a very high risk of developing complications after procedure. We present a clinical case of successful and safe use of carboxyangiography for renal artery denervation in a patient with resistant arterial hypertension (HTN) in combination with type 2 diabetes mellitus and CKD against the background of an allergic reaction to iodine contrast agents in the form of an anaphylactoid reaction in anamnesis (angioedema). An alternative type of angiography allowed us to carry out successful endovascular treatment of HTN resulting in the achievement of target blood pressure levels without intervention-related complications at early- and long-term follow-up.
