Diagnosis and Management of Arterial Stenosis Causing Hypertension after Successful Renal Transplantation

Abstract

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.

Peripheral vascular disease and renal transplant artery stenosis: a reappraisal of transplant renovascular disease

“…These signs and symptoms, when they characterize RTAS, usually occur between 3 months and 2 yr post‐transplantation. Our retrospective single‐center review identified RTAS in 3.7% of all studied kidney transplant recipients, a value similar to other reports of RTAS in the literature [1,2,10,11].…”

Renal Artery Stenosis in Transplanted Kidney: Management and Results in Six Patients

“…Nevertheless, of the 24-60% HT appearing in trans planted patients, only 10-12% seem to be renovascular HT [2][3][4][5], Thus between 4 and 6% of transplanted kid neys have HT caused by RAS. Clinically it resembles severe HT with a reduction of renal function with or without oliguria and, in the area of the graft, an arterial bruise appears.…”

Renal allograft artery stenosis: results of medical treatment and intervention. A retrospective analysis

“…Management of this cause of hypertension consists of either pharmacological treatment or correction of the stenosis. Correction may be attempted by percutaneous transluminal angioplasty (PTA) [I, 121 or by surgical repair [15,16]. The choice between these three treatment modalities is often difficult since data on the early and long-term results of these treatments are limited.…”
