Abstract
Embolization of end-stage kidneys using our own embolizing agent Vilanol (partially hydrolyzed polyvinyl acetate) was performed in 10 patients with hypertension refractory to conservative therapy. Native kidneys were embolized in 7 patients with chronic renal failure, nonfunctioning renal transplants in 2 patients, and a shrunken kidney in 1 patient. Five of the 10 patients had high (9.96–18.2 ng/ml/h) peripheral renin (PR) levels. The embolization was technically successful in 4 of these 5 patients and was immediately followed by a marked decrease in PR, and simultaneous improvement in blood pressure (BP). The other 5 patients had very low PR levels (0.07–0.65 ng/ml/h), and a reduction in BP was observed in 4 after embolization. One patient died following embolization from cardiac arrest due to hyperkalemia. Six patients (3 in each group) have been on follow-up for 2–5 years with sustained decrease in BP. We conclude that the new agent is effective for renal ablation and control of refractory hypertension.
