Endovascular treatment of patients with renal artery stenosis: A case series

Renal artery stenosis (RAS) is the most common cause of secondary systemic hypertension. The efficacy of endovascular treatment
of patients with RAS, who achieved antihypertensive optimal medical treatment (OMT), is unclear. But it may be useful in some selected clinical scenarios, including cardiac disturbance, resistant hypertension and ischemic nephropathy.
Case Report: Our first patient suffered from resistant hypertension with end organ damages (EOD), due to significant bilateral RAS. In the second and third patients, the severe unilateral RAS was presented by resistant and malignant hypertension. In all three patients, hypertension had become under controll by medical treatment after renal artery stenting.
It seems that renal artery stenting is an effective and safe adjuvant approach in addition to the medical treatment of patients with RAS, in whom their hypertension is not only unversponsive to the OMT, but also causes EOD.
