Refractory Hypertension Due To Renal Artery Stenosis In A Solitary Kidney: Case Report And Literature Review

In this article we reported a patient with the refractory hypertension which attribute to the severe atherosclerotic renal artery stenosis (ARAS) in a solitary kidney. The percutaneous transluminal renal angioplasty with stent (PTRAS) was proved to be an effective method in refractory hypertension. Then we systematically reviewed related articles to evaluate the benefit of PTRAS on patients with ARAS, especially those who combined with other certain clinical conditions. Although several clinical trials failed to show that stenting has any significant benefit over medical therapy in ARAS, we propose that the procedure should be considered as a viable option for acute critical cases.
