Current Status of Renal Arterial Endovascular Interventions

Endovascular renal arterial interventions remain important treatment strategies for symptomatic renal artery stenoses causing either renovascular hypertension, renal insufficiency, or cardiac disturbance syndromes. Since endovascular intervention has not been shown to be efficacious over optimal medical therapy, it should be reserved for certain specific indications, as well as whenever medical therapy has failed. This review will discuss the current indications, patient selection methods, technique, imaging follow up, adjunctive revascularization techniques,and complications of endovascular treatment of renal artery stenoses, as well as the current trials comparing endovascular treatment to medical therapy.
