Abstract
Radiocontrast-induced nephropathy (CIN) is one of the most serious complications of percutaneous coronary interventions (PCI). The prevention of PCI-related CIN for chronic kidney disease (CKD) patients has not been established yet. The intravascular ultrasound (IVUS) is commonly used as an imaging device during PCI. We performed IVUS-guided PCI while only using fluoroscopic imaging and without administering any routine contrast dye injection during the procedures. All patients underwent a baseline coronary angiography prior to the elective PCI. During the PCI, all the following procedures were done with X-ray fluoroscopic imaging without or with a minimized contrast dye injection: the engagement of the guiding catheter, insertion of the coronary guidewire, insertion of the IVUS catheter, the stent deployment and the post-dilatation. The diameter and the length of the balloon and the stent were determined according to the pre-procedural IVUS findings, and the end point of the stent dilatation was also judged according to the acquired minimal cross-sectional area of the stent. Here we report our findings from two cases representative of IVUS-guided minimum contrast PCI in which the volumes of contrast dye during the procedure were 5 and 4 ml, respectively. No CIN occurred after either procedure. The IVUS-guided minimum contrast PCI could be a promising option for the prevention of CIN after PCI.
