Embolization and angioplasty to relieve malignant hypertension and azotemia in a renal transplant patient.

The case of a 23-year-old patient with malignant hypertension following a renal transplant illustrates the successful treatment of the hypertension with embolization of the native kidneys. Azotemia followed and was successfully treated with percutaneous transluminal angioplasty of high-grade stenosis at the anastomotic site of the allograft. Malignant hypertension redeveloped with the recanalization of the embolized native kidneys. This was successfully treated with contrast ablation.
