Renal ostial angioplasty and stenting. Part 1: the routine procedure.

Renal ostial stenting (ROS) is the most common endovascular intervention for treatment of atherosclerotic renal artery stenosis. The two most common indications for ROS are refractory hypertension and progressive renal insufficiency. It is important to recognize that this intervention is most often done to mitigate either or both problems and will rarely “cure” either. ROS remains controversial with published data that both support and refute its utility. This article is the first in a two-part series dedicated to performing the “typical” procedure. The second part will deal with common problems and complications.
