Abstract

To assess feasibility, efficacy and safety of carbon dioxide (CO2) digital subtraction angiography (DSA) to guide endovascular aneurysm repair (EVAR) in a cohort of patients with chronic kidney disease (CKD). After Ethical Committee approval, the records of 13 patients (all male, mean age 74.6 ± 8.0 years) with CKD, who underwent EVAR to exclude an abdominal aortic aneurysm (AAA) under CO2angiography guidance, were reviewed. The AAA to be excluded had a mean diameter of 52.0 ± 8.0 mm. CO2angiography was performed by automatic (n = 7) or hand (n = 6) injection. The endograft was correctly placed and the AAA was excluded in all cases, without any surgical conversions. Two patients (15.4%) had an endoleak: one type-Ia, detected by CO2-DSA and effectively treated with prosthesis dilatation; one type-III, detected by CO2-DSA, confirmed using 10 ml of ICM, and conservatively managed. In one patient, CO2angiograms were considered of too low quality for guiding the procedure and 200 ml of ICM were administered. Overall, 11 patients (84.6%) underwent a successful EVAR under the guidance of the sole CO2angiography. No patients suffered from major complications, including those typically CO2-related. Two patients suffered from abdominal pain during the procedure secondary to a transient splanchnic perfusion’s reduction due to CO2, and one patient had a worsening of renal function probably caused by a cholesterol embolization during the procedure. In patients with CKD, EVAR under CO2angiography guidance is feasible, effective, and safe.
