Peripheral angioplasty refers to the use of a balloon to open a blood vessel outside the coronary arteries. It is most commonly done to treat atherosclerotic narrowings of the abdomen, leg and renal arteries caused by peripheral artery disease. Often, peripheral angioplasty is used in conjunction with guide wire, peripheral stenting and an ...
Angiography is also commonly performed to identify vessels narrowing in patients with leg claudication or cramps, caused by reduced blood flow down the legs and to the feet; in patients with renal stenosis (which commonly causes high blood pressure) and can be used in the head to find and repair stroke. These are all done routinely through the ...
Renal artery stenosis, or narrowing of one or both renal arteries will lead to hypertension as the affected kidneys release renin to increase blood pressure to preserve perfusion to the kidneys. RAS is typically diagnosed with duplex ultrasonography of the renal arteries. It is treated with the use of balloon angioplasty and stents, if necessary.
Renal artery stenosis (RAS) is the narrowing of one or both of the renal arteries, most often caused by atherosclerosis or fibromuscular dysplasia. This narrowing of the renal artery can impede blood flow to the target kidney , resulting in renovascular hypertension – a secondary type of high blood pressure .

Percutaneous transluminal renal angioplasty (PTRA) is considered the best treatment for renal-artery FMD. It is useful when hypertension is difficult to control, such as when the patient is intolerant to the anti-hypertensive medications, non-compliant to medication regime, or experiencing loss of renal volume due to ischemia.
Medical imaging may include ankle-brachial index, doppler ultrasonography and computed tomography angiography, among others. Treatments are individualized and may include medical therapy, endovascular intervention or open surgical options including angioplasty, stenting, atherectomy, endarterectomy and vascular bypass, among others.
Magnetic resonance angiography (MRA) is a group of techniques based on magnetic resonance imaging (MRI) to image blood vessels. Magnetic resonance angiography is used to generate images of arteries (and less commonly veins) in order to evaluate them for stenosis (abnormal narrowing), occlusions, aneurysms (vessel wall dilatations, at risk of rupture) or other abnormalities.
