Summary

Diagnostic imaging for vascular investigations and endovascular procedures frequently require the use of contrast medium. Besides contrast medium-induced hypersensitivity, an acute kidney injury can appear: the contrast-induced nephropathy (NPCI).

NPCI is associated with an increase of patients' morbidity and mortality. One of the conventional methods proposed to limit this NPCI is an oral administration of N-acetylcysteine (NAC) associated with hydration performed 12 hours before and 12 hours after the injection. However, in some patients this method cannot be performed due to a high risk of heart failure although they are generally at high risk of NPCI.

Recently, it has been shown, in a randomized trial, that remote ischemic preconditioning (several cycles of upper-arm ischemia-reperfusion with a pressure cuff inflator) associated with hydratation and NAC reduced the occurrence of NPCI after a coronary angiography as compared with NAC and hydration only. .

We hypothesized that the use of RIPC in patients at high risk of NPCI and who cannot receive NAC and hydratation (e.g. patients with aortic stenosis and eligible for Transcatheter Aortic Valve Implantation (TAVI)) could be promising.

Conditions

  • Nephropathy

Interventions

OTHER

Remote Ischemic Preconditioning (RIPC)

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.

OTHER

SHAM Remote Ischemic Preconditioning (SHAM RIPC)

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).
