Renal artery stenting

Renovascular hypertension due to renal artery stenosis can be cured or ameliorated with renal artery angioplasty. Accurate clinical evaluation of the patient is mandatory in putting an interventional therapy indication. Additional use of renal stent has been proven mandatory in renal artery ostial lesions and in suboptimal angioplasty of true renal artery stenosis. Renal stent should not be implanted in cases of fibromuscular dysplasia where its use is strictly limited to possible complications of percutaneous angioplasty. Accurate choice of vascular access and gentle negotiation of proper hardware are the keys to avoid damage by macro and microembolization to the kidneys. Possible complications should be recognized and promptly treated.
