Digital Variance Angiography (DVA) is a new tool in medical imaging with a proven image quality reserve (1, 2).
Previous studies have demonstrated the quality reserve of DVA in angiographic studies (1, 2), which allowed us to reduce contrast media use by 50% in carotid artery angiographic studies without affecting the image quality (3).
CAS is an alternative treatment option for carotid artery revascularization in selected patient groups. Similar to most of the minimally invasive endovascular interventions, CAS also carries the risk of contrast-induced acute kidney injury, which is considered to be an independent predictor of 30-day major adverse events (4).
The aim of this study is to apply DVA in patients undergoing carotid artery stenting (CAS) and utilize this technique to reduce contrast dose during the interventions, without affecting the intraprocedural radiation dose and the clinical outcome of the procedures. Investigators believe that the reduction in contrast media use and the associated image quality with the technique of DVA imaging can be incorporated into the everyday clinical practice, and will play an important role in improving the rate of contrast-induced acute kidney injury.
