Percutaneous recanalization of an occluded renal artery and delayed ethanol ablation of the kidney resulting in control of hypertension.

An elderly woman presented with severe hypertension related to a renin producing kidney supplied only by collaterals. Recanalization of the artery to this kidney leads to incomplete blood pressure control. Subsequently, percutaneous, selective ethanol infusion ablated the kidney and lead to good control. This two-step approach allowed both evaluation of function and definitive, non-surgical therapy.
