Editing Angiography (section)

===Peripheral angiography===
Angiography is also commonly performed to identify vessels [[stenosis|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 femoral artery, but can also be performed through the brachial or axillary (arm) artery.  Any stenoses found may be treated by the use of balloon angioplasty, stenting, or [[atherectomy]].
