Diagnosis and management of arterial stenosis causing hypertension after successful renal transplantation.

Renal artery stenosis causing hypertension has been noted in 11 patients after successful renal transplantations. We believe that all patients with moderate to severe post-transplant hypertension should be evaluated with angiography and selective renin determinations. However, because of definite risk to the graft we believe that operative intervention should be undertaken only if hypertension is uncontrolled or if declining renal function is present and attributable to the stenosis.
