Imaging-guided percutaneous coronary intervention with ultra-low contrast angiographic control for patients at extreme risk of contrast induced nephropathy

摘要

The occurrence of contrast induced nephropathy (CIN) remains one of the gravest complications of percutaneous coronary intervention (PCI) and is related to increased morbidity and mortality [1, 2]. In select cases renal replacement therapy is required, increasing the rate of major adverse events [3]. Minimizing contrast administration and optimal fluid management are effective in prevention [4], but in select patients a minimal quantity of contrast may lead to CIN. Since indicated the first feasibility reports [5–7], the concept of intravascular ultrasound (IVUS) guided PCI has become appealing for patients at risk of CIN. Presented herein, is a series of IVUS-guided PCI cases with ultra-low contrast volume angiographic control.
