ANGIOTENSIN-CONVERTING ENZYME (ACE) INHIBITORS ISOTOPE RENOGRAM

CAPTOPRIL TEST

DESCRIPTION

The Captopril test is performed as part of the differential diagnosis test for vasculorenal high blood pressure, and for the evaluation of a possible renal uni or bilateral artery stenosis. It implies two procedures: abase study and a Captopril study, for the evaluation of the function of the kidneys, renal perfusion and glomerular filtration in both situations.

PREPARATION

  • The patient must hydrate with 200-250 ml of liquid and pee before the scan.
  • In infants, the renogram is made just at the end of breastfeeding. Older children don’t need to fast and hydration varies according to age (50-250 ml).
  • After consultation with the prescribing physician, ACE medication must be withdrawn  6 days before the procedure.
  • It is also advisable to stop other medications:

    • Beta blockers: 2 days before.
    • Limit antagonists: 24 hours before.
    • Diuretics: 2 days before.

INDICATIONS

Diagnosis of vasculorenal arterial hypertension.
