When high-grade renal artery stenosis is documented and blood pressure cannot be controlled with medication, or if renal function deteriorates, surgery may be resorted to. The most commonly used procedure is a minimally-invasive angioplasty with or without stenting .
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.
Atherosclerotic obstruction of the renal artery can be treated with angioplasty with or without stenting of the renal artery. [10] There is a weak recommendation for renal artery angioplasty in patients with renal artery stenosis and flash edema or congestive heart failure. [10]
Carotid endarterectomy: A carotid endarterectomy is a minimally invasive procedure to remove plaque from within your carotid artery, the main blood vessel that carries blood to your brain.
In 1986, he classified TAAA open surgery cases into four types: [22] Extent I, extending from the left subclavian artery to just below the renal artery; Extent II, from the left subclavian to below the renal artery; Extent III, from the sixth intercostal space to below the renal artery; and Extent IV, from the twelfth intercostal space to the ...
The procedure involves endovascular access via the femoral artery with advancement of a catheter-mounted device into the renal artery. The device uses radiofrequency or ultrasound to ablate the renal nerves. Typically, numerous ablations are applied at a different longitudinal and rotational positions to ensure maximal denervation.

Radial access has also been used successfully to treat peripheral artery disease including bilateral iliac artery stenosis, renal artery stenosis and for carotid interventions. [ 10 ] [ 11 ] Due to rapid ambulation post procedure the radial interventions became particularly attractive for patients with back pain, chronic obstructive lung ...
