The ratio of contrast medium volume to estimated glomerular filtration rate as a predictor of contrast‐induced nephropathy after endovascular aortic repair

Abstract

The CV/eGFR ratio was a useful predictor of contrast medium-induced nephropathy after EVAR. It is possible that the score can be used in patients when managing the EVAR techniques and contrast medium volume. J. Med. Invest. 65:116-121, February, 2018.

Incidence of Contrast-Induced Nephropathy and Post-Operative Outcomes in Patients Undergoing Chimney Endovascular Aortic Aneurysm Repair

“…Several pre-operative risk factors of CI-AKI have been identified including the age of the patients and baseline kidney function. [14][15][16][17]44 Although they are well-established risk factors of CI-AKI, we did not observe a significant difference regarding these two factors in our cohort between patients who developed CI-AKI and those who did not. However, it is possible that the distribution of age in our cohort may not have allowed to identify a significant difference.…”

“…12,13 Previous studies reported an incidence of CI-AKI in patients undergoing EVAR between 6.9 and 28%. 12,[14][15][16][17][18][19][20] In the present cohort of 102 patients, we report for the first time, the incidence of CI-AKI specifically in patients who underwent ch-EVAR, with a rate of 13.7%, which is within the low range compared with other EVAR procedures. In our center, we applied an "as low as reasonably achievable" approach and the median of CM used was low (85 mL), which could partly explain a relatively low rate of incidence of CI-AKI.…”

“…In a cohort of 203 patients who underwent EVAR, others found that the volume of CM administered was significantly higher in patients who developed contrast-induced nephropathy compared with those who did not (104.4 vs 85.5 mL, P = .019). 15 However, in another cohort including 214 patients treated with EVAR, no correlation was found between CM volume and the final eGFR. 20 In our cohort, we did not find a significant difference in the amount of CM used between the patients who developed CI-AKI and those who did not (90.0 vs 84 mL, P = .583).…”

“…[9][10][11] The occurrence of CI-AKI has been reported during diagnostic or therapeutic procedures in patients with vascular diseases, including aortic aneurysms. 12,13 While several studies reported its incidence in patients undergoing EVAR, [14][15][16][17][18][19][20] none of them has specifically addressed this issue in the context of ch-EVAR. This study aims to report the occurrence of CI-AKI in patients undergoing ch-EVAR and to investigate its association with post-operative outcomes.…”

The Ratio of Fibrinogen to Albumin as a Predictor of Contrast-Induced Nephropathy After Carotid Angiography

“…31 Furthermore, the ratio of contrast media volume to GFR was demonstrated to predict CIN after endovascular aortic repair. 32 A relationship has also been established between increased baseline proteinuria and CIN in patients undergoing renal artery stent placement. 33 C-reactive protein was found to be an independent predictor of CIN after coronary angiography.…”
