ACUTE TRANSPLANT ARTERY THROMBOSIS INDUCED BY ANGIOTENSIN-CONVERTING INHIBITOR IN A PATIENT WITH RENOVASCULAR HYPERTENSION

Acute renal failure due to angiotensin-converting enzyme inhibitors (A CEI) usually results from a marked fall in renal perfusion pressure in patients with renovascular disease. We report herein one case of acut e kidney transplant artery thrombosis in a patient with renovascular h ypertension. The thrombosis occurred immediately after a single dose o f ACEI for evaluation of a renal transplant artery stenosis by renal s cintigraphy. The dramatic fall of arterial pressure observed in our pa tient probably played an important role in the thrombosis. The risk of the administration of a single dose of ACEI coupled with renal scinti graphy in diagnosing renovascular hypertension is stressed.
