Interest of Remote Ischemic Preconditioning for Prevention of Contrast Medium-induced Nephropathy in High Risk Patients

"RIPC is accomplished by performing 4 cycles of alternating 5-minute inflation and 5-minute deflation of a standard upper-arm blood pressure cuff, to induce transient and repetitive arm ischemia and reperfusion.~RIPC will be started just before the CTA, and the time between the last inflation cycle and the beginning of the CTA will be less than 45 minutes."

"The SHAM Remote Ischemic Preconditioning (SHAM RIPC) will be carried out with the same number of cycles that the RIPC but cuff will be inflated to the diastolic pressure of the subject and the cuff will be deflated to10 mmHg in order to maintain a non- ischemic compression (blind patient protocol)."
